Selection against Neandertal deleterious alleles“‘Approximately 2-4% of the human genome is in non-Africans comprised of DNA intro- gressed from Neanderthals. Recent studies have shown that there is a paucity of introgressed DNA around functional regions, presumably caused by selection after introgression. [U]sing previously published estimates of inbreeding in Neanderthals, and of the distribution of fitness effects from human protein coding genes, we show that the average Neanderthal would have had at least 40% lower fitness than the average human due to higher levels of inbreeding and an increased mutational load, regardless of the dominance coefficients of new mutations. Using simulations, we show that under the assumption of additive dominance effects, early Neanderthal/human hybrids would have experienced strong negative selection, though not so strong that it would prevent Neanderthal DNA from entering the human population.'” – @dienekes’…

…but see greg cochran: Degenerate Neanderthals“Part of the problem is that the model is probably too simple. There is an argument, which makes sense to me, that suggest that small-N populations do better than you would think, because as the average population fitness gets farther from the optimum, strongly beneficial compensatory mutations become more and more possible.”

A Few Months of Evolutionary Change Reshapes a Whole Community“The overall lesson is that evolutionary change is constant, and that evolving populations can change the very environments to which they’re adapting. Natural selection isn’t shaping species to achieve some single ideal version of themselves, but in pursuit of constantly moving targets — and that’s worth keeping in mind no matter we’re talking about Daphnia magna or Homo sapiens.”

Size (Population) Matters for Inbreeding“Presumably, in large populations there will be many low frequency variants of weak deleterious effect and recessive expression. In contrast, in small populations the power of drift is such that even rather deleterious alleles can be fixed against the gradient of selection. At cross-purposes with this is the idea that because inbreeding populations tend to ‘expose’ alleles which express recessively to selection they can ‘purge’ the genetic load which drags on fitness…. What [the researchers] found is that in line with theoretical prediction those sampled from large populations had lots of segregating deleterious alleles, which manifested in strong inbreeding effect when individuals were purposely crossed with those genetically similar. In contrast, those from small populations did not exhibit so much inbreeding effect, indicating that a lot of the deleterious alleles were already fixed and so exposed. These individuals from small populations also exhibited lower fitness than those from large populations, reflecting in all likelihood their genetic load. Crossing individuals from different small populations resulted in immediately hybrid vigor, as the fixed variants differed across lineages.” – from razib.

Fires in the Forest: The Revolution in Human Evolution“On top of the story of migrations of whole peoples, and the extinction and absorption of others, is the story of bands of men operating as units, related either in truth or fictively, which extract rents across a thickly populated landscape of human cattle.” – also from razib.

The Correlation Between g Loadings and Heritability in Russia“Data from 402 twins aged 13 and 296 twins aged 16 showed correlations of r=−0.45 and r=−0.60, respectively. It is concluded that the two data points are clearly not in line with established findings. It may be that the link between g loadings and heritabilities is more complex than previously thought.” – h/t sketchy person!

Are CEOs Born Leaders? Lessons from Traits of a Million Individuals“CEOs have higher cognitive and non-cognitive ability scores and are taller than typical members of the population.

The Quantitative Genetics of Disgust Sensitivity“Twin modeling revealed that approximately half of the variation in pathogen, sexual, and moral disgust is due to genetic effects. An independent pathways twin model also revealed that sexual and pathogen disgust sensitivity were influenced by unique sources of genetic variation, while also being significantly affected by a general genetic factor underlying all 3 disgust domains. Moral disgust sensitivity, in contrast, did not exhibit domain-specific genetic variation.” – h/t erwin schmidt!

Can intelligence explain the overrepresentation of liberals and leftists in American academia?“Liberals and leftists are overrepresented in American academia. One explanation is that liberals and leftists have higher intelligence. This hypothesis is tested. Intelligence accounts for some but not all of the overrepresentation.”

Inter-group conflict and cooperation: field experiments before, during and after sectarian riots in Northern Ireland“The idea that cooperative groups out-compete less cooperative groups has been proposed as a theoretical possibility for the evolution of cooperation through cultural group selection…. In this study we test the hypothesis that inter-group conflict promotes parochial altruism (i.e. in-group altruism and out-group hostility) by using longitudinal data of a real-world measure of cooperation – charity and school donations – sampled before, during and after violent sectarian riots between Catholics and Protestants in Belfast, Northern Ireland. We find that conflict is associated with reductions in all types of cooperation, with reduced donations to a neutral charity, and both in-group and out-group primary schools. After the conflict, both in-group and out-group donations increased again. In this context we find no evidence that inter-group conflict promotes parochial altruism.”

Interactions between personality and institutions in cooperative behaviour in humans“We investigate interactions between personality and a punishment situation via two versions of a public goods game. We find that, even in a strong situation, personality matters and, moreover, it is related to strategic shifts in cooperation. Extraversion is associated with a shift from free-riding to cooperation in the presence of punishment, agreeableness is associated with initially higher contributions regardless of game, and, contrary to our predictions, neuroticism is associated with lower contributions regardless of game. Results should lead to new hypotheses that relate variation in biological functioning to individual differences in cooperative behaviour and that consider three-way interactions among personality, institutional context and sociocultural background.” – h/t andrew sabisky!

Nonreligious children are more generous“Religious doctrines typically urge the faithful to treat others with compassion and to put the greater good before selfish interests. But when it comes to generosity, nonreligious kids seem to be more giving, according to a new study of 1170 children from around the world. Children from religious homes — particularly Muslims — also showed a greater inclination to judge someone’s misdeeds as wrong and punish the perpetrators…. Muslim children on average gave the highest rankings and sought harsher punishments than either their Christian or secular counterparts. Decety says he is unsure why this is the case.” – h/t jayman! see also staffan who tweeted: “Religious or not often coincide with Clannish and WEIRDO.

Sex and STEM Occupation Predict Autism-Spectrum Quotient (AQ) Scores in Half a Million People“As predicted, sex and occupation differences were observed: on average, males (m = 21.55, SD = 8.82) scored higher than females (m = 18.95; SD = 8.52), and individuals working in a STEM career (m = 21.92, SD = 8.92) scored higher than individuals non-STEM careers (m = 18.92, SD = 8.48). Also as predicted, age and geographic region were not meaningfully correlated with AQ. These results support previous findings relating to sex and STEM careers in the largest set of individuals for which AQ scores have been reported and suggest the AQ is a useful self-report measure of autistic traits.”

Seven Dimensions Of Personality Pathology Are Under Sexual Selection In Modern Spain“In a sample of 959 outpatients, we examine whether, and how, sexual selection acts on seven main dimensions of personality pathology, taking into account mating success, reproductive success, and the mediating role of status. We find that, to varying extents, all personality dimensions are under sexual selection. Far from being predominantly purifying, selective forces push traits in diverging, often pathological, directions. These pressures differ moderately between the sexes. Sexual selection largely acts in males through the acquisition of wealth, and through the duration (rather than the number) of mates. This gives a reproductive advantage to males high in Persistence-Compulsivity. Conversely, because of the decoupling between the number of mates and offspring, the promiscuous strategy of psychopaths is not so successful. Negative Emotionality, the most clinically detrimental trait, is slightly deleterious in males but is positively selected in females, which can help to preserve variation…. An evolutionary perspective on PDs can provide a better understanding of their nature and causes than we have achieved to date by considering them as illnesses.” – h/t siberian fox!

No evidence that polygynous marriage is a harmful cultural practice in northern Tanzania“We present counterevidence that polygyny is often positively associated with food security and child health within communities and that, although polygyny and health are negatively associated at the group level, such differences are accounted for by alternative socioecological factors. These results support models of polygyny based on female choice and suggest that, in some contexts, prohibiting polygyny could be costly for women and children by restricting marital options.” – h/t sergey gavrilets!

The missing hour of sleep“In reality, there is no single human nature. Genetic evolution didn’t slow down when humans began to split up and settle the different continents. It accelerated. And not just because our ancestors were adapting to different natural environments. Most of the acceleration took place long after the globe had been settled from the equator to the arctic. It happened when humans began to adapt to an increasingly diverse range of cultural environments. And those adaptations were mostly behavioral and psychological. One of them is the way we sleep. The African sleep pattern is normal in its native environment. It is simply an adaptation to a particular set of circumstances, just as the northern European sleep pattern is an adaptation to another set of circumstances.” – also from peter frost.

cpi 2014 - europe

…on twitter, that a chorus of people will respond: oh, just look at the terrible effects communism had on eastern europe! for no good reason really because, as we all know, correlation does not equal causation — although it does “waggle its eyebrows suggestively and gesture furtively while mouthing ‘look over there.'”

just because soviet regimes were present in the past in the same areas of europe where there are high corruption levels today does not mean the one is the cause of the other. (and anyway…look at the regions beyond europe! or southern europe, for that matter.) the relationship is certainly suspicious though, and it wouldn’t be surprising if the two were somehow connected.

one way to try to settle this debate would be to look at pre-soviet corruption rates in eastern europe versus the west to see if the situation was any different beforehand.

i have not done that in this post, in large part because i don’t speak any slavic or other eastern european languages, but primarily because it seemed like way too much work. instead, i’m going to take a look a civicness, a set of behaviors — along with things like intelligence, low amounts of corruption, and low levels of violence — that many researchers reckon are necessary in order to have western-style liberal democracies and economies, if that’s what you want in life. i’ll be focusing on russia, again just to kept this little project manageable. but first, italy.

in Making Democracy Work: Civic Traditions in Modern Italy, robert putnam (yes, that robert putnam) concluded that democracy in northern italy functions better than in the south because the north has had a longer tradition — stretching back to the middle ages — of civicness or of having a civic community. (see previous post: democracy in italy.) according to putnam [pgs. 88-89, 91]:

“Citizenship in the civic community entails equal rights and obligations for all. Such a community is bound together by horizontal relations of reciprocity and cooperation, not by vertical relations of authority and dependency. Citizens interact as equals, not as patrons and clients nor as governors and petitioners….

“Citizens in a civic community, on most accounts, are more than merely active, public-spirited, and equal. Virtuous citizens are helpful, respectful, and trustful towards one another, even when they differ on matters of substance….

“One key indicator of civic sociability must be the vibrancy of associational life.”

in civic societies and civic societies ii, i looked at (self-reported) participation rates in voluntary associations across the world as found in the 2005-2008 wave of the world values survey. specifically, i tallied up the number of individuals who responded that, yes, they were ACTIVE members of the following voluntary associations (thus giving some indication of how civic-minded each of the populations is):

– Church or religious organization
– Sport or recreation organization
– Art, music or educational organization
– Labour union
– Political party
– Environmental organization
– Professional association
– Charitable organization
– Any other voluntary organization

the response rates for eastern europe were abysmal, often vying for last place with the middle east (see previous post for more):

wvs - membership voluntary organizations - totals

not much has changed in the latest wave (2010-2014). here, for example, are the active membership rates for the russian federation for each of the organization types — the first figure is from the 2005-2008 wave, the second from 2010-2014:

– Church or religious organization = 2.60% – 2.00%
– Sport or recreation organization = 5.90% – 2.40%
– Art, music or educational organization = 4.20% – 1.50%
– Labour union = 3.40% – 2.00%
– Political party = 0.80% – 0.50%
– Environmental organization = 0.40% – 0.40%
– Professional association = 1.60% – 1.40%
– Charitable organization = 1.10% – 0.6%
– Any other voluntary organization = n/a – 1.4%

as joseph bradley says in Voluntary Associations in Tsarist Russia: Science, Patriotism, and Civil Society (2009), russia is “not known as a nation of joiners.” apparently not! (mind you, i am not in a position to cast any stones on this account. *ahem*)

but were the russians more civic-minded before the revolution?

unfortunately, i don’t have any figures which can be directly compared to our modern world values surveys, but, yes, there was some amount of participation in voluntary civic institutions in russia in the two hundred years or so preceding 1917. however, civic participation didn’t begin in russia until the mid-1700s (and that is a key point to which i’ll return), and for most of that period, it occurred mostly among the upper classes. participation rates did grow across the nation and classes over the next century and a half, until just after the revolution of 1905 when there was a rapid rise in one sort of voluntary association — consumer cooperatives — among all classes of russians. however, civil society was still comparatively shallow in early-twentieth century russia — it hadn’t fully penetrated the whole of society by that point yet because the concept was so relatively new to the populace. here is laura engelstein in “The Dream of Civil Society in Tsarist Russia: Law, State, and Religion” (2000) quoting the sardinian antonio gramsci on the matter [pg. 23]:

“On the margins of the European state system, sharing but not fully integrating the Western cultural heritage, Russia, it is said, has always lacked just these civic and political traits. Antonio Gramsci provides the classic statement of this contrast: ‘In Russia,’ he wrote in the 1920s, ‘the state was everything, civil society was primordial and gelatinous; in the West there was a proper relation between state and civil society, and when the state trembled a sturdy structure of civil society was at once revealed.’ When in 1917 the Russian autocracy not only trembled but tumbled to the ground, there was no ‘powerful system of fortresses and earthworks,’ in Gramsci’s phrase, to prevent the Bolsheviks from erecting another absolutist regime in its place.”

civic society in russia first came to life under catherine the great (1729-1796), who did go some way to promote enlightenment ideals in the empire; perhaps more so when it came to the arts rather than politics, but still…it was a start, albeit one restricted in extent. from engelstein again [pg. 26 – my emphasis]:

“Eighteenth-century Russia had a lively public life. Private presses, a market in print, debating societies, literary salons, private theaters, public lectures, Masonic lodges — all linked inhabitants of the capitals and provincial centers in something of an empirewide conversation. Yet this world was limited in scope, audience, and resources and was fatally dependent on the autocrat’s good will. Catherine, when it pleased her, cracked down on independent publishers.”

this public life did continue to grow, however, although in fits and starts. nicholas i (1796-1855) was not too thrilled by it all, and alexander i (1777-1825) actually banned the freemasons, but by the nineteenth century, alexander ii (1818-1881) was, for a tsar, positively a radical when it came to permitting and promoting civic society as was evident in his great reforms. by the late nineteenth century then [pg. 16]:

“…an increasingly active public sphere of debate that included advocacy and representation was no longer in doubt in tsarist Russia. Thus well before the Revolution of 1905, the groundwork was laid for the participation of private associations in the public arena.”

the practice of joining voluntary organizations came later to the russian lower classes. consumer cooperatives began to appear in russia and the empire in the 1860s, but these first cooperatives were organized and run by the upper classes. peasants and workers would’ve been customers only. cooperatives among middle class professionals in towns and cities appear in the early-1890s. the idea spread to villages in 1900 via proselytizing intellectuals (also worth noting), and after 1905, the cooperative movement exploded right across the country. from The Co-operative Movement in Russia: Its History, Signficance, and Character (1917) by j.b. bubnoff — delightfully published in manchester by the co-operative printing society limited (so the work could be a bit biased) [pg. 49]:

“In 1891 consumers’ societies were formed in towns among the lower-grade officials, various classes of employees, teachers, members of liberal professions, and other sections of the population. These societies were of two types. One open only to members of a particular class of officials or to employees of a particular firm or institution; the other was open to all. These latter societies were already marked by the spirit of independence.

“Throughout this period the number of consumers’ societies was not large, and their output was small…. In 1900 the position was the same. Beginning from 1900, the Co-operative Movement spread in the villages…. [T]he first consumers’ societies in the villages were initiated by the intellectuals and by the authorities and were not the outcome of free enterprise on the part of the peasants themselves. At the end of the last century, and particularly at the beginning of the present one, an agrarian movement spread among the peasantry and ended in the revolution of 1905.”

by 1917, provided bubnoff wasn’t exaggerating, there were ca. 20,000 consumer cooperatives in russia (bubnoff notes that the other organizations listed in the table below — credit and loan savings associations, agricultural societies, and the artels — were all either government run or arranged by the large landowners, so they weren’t really voluntary associations in the sense of being organized by the members.):

Russia - The co-operative movement in Russia - table

again, though, this is late for finally getting around to launching civic institutions in your country. nineteen hundred and seventeen (1917) is very, very late compared to what happened in northwestern europe. even compared to what happened in northern italy. as valerie bunce says in “The Historical Origins of the East-West Divide: Civil Society, Politcal Society, and Democracy in Europe” [pg. 222]:

“By the end of the nineteenth century, then, it was evident that there were two Europes, long separated by their histories and, thus, by their politics, economics, social structure, and culture.”

not to mention their evolutionary histories.

so how did northwestern “core” europe (including northern italy) differ from russia historically as far as participation in civic institutions goes? the short answer is: civicness in “core” europe began centuries before it did in russia or the rest of eastern europe, at least 500-600, if not 800-900, years earlier.

here is putnam on the formation and functioning of communes in northern italy beginning in the 1000s [pg. 124-126]:

“[I]n the towns of northern and central Italy…an unprecedented form of self-government was emerging….

“Like the autocratic regime of Frederick II, the new republican regime was a response to the violence and anarchy endemic in medieval Europe, for savage vendettas among aristocratic clans had laid waste to the towns and countryside in the North as in the South. The solution invented in the North, however, was quite different, relying less on vertical hierarchy and more on horizontal collaboration. The communes sprang originally from voluntary associations, formed when groups of neighbors swore personal oaths to render one another mutual assistance, to provide for common defense and economic cooperation…. By the twelfth century communes had been established in Florence, Venice, Bologna, Genoa, Milan, and virtually all the other major towns of northern and central Italy, rooted historically in these primordial social contracts.

“The emerging communes were not democratic in our modern sense, for only a minority of the population were full members…. However, the extent of popular participation in government affairs was extraordinary by any standard: Daniel Waley describes the communes as ‘the paradise of the committee-man’ and reports that Siena, a town with roughly 5000 adult males, had 860 part-time city posts, while in larger towns the city council might have several thousand members, many of them active participants in the deliberations….

“As communal life progressed, guilds were formed by craftsmen and tradesmen to provide self-help and mutual assistance, for social as well as for strictly occupational purposes. ‘The oldest guild-statute is that of Verona, dating from 1303, but evidently copied from some much older statute. “Fraternal assistance in necessity of whatever kind,” “hospitality towards strangers, when passing through the town”…and “obligation of offering comfort in the case of debility” are among the obligations of the members.’ ‘Violation of statutes was met by boycott and social ostracism….’

“Beyond the guilds, local organizations, such as *vicinanze* (neighborhood associations), the *populus* (parish organizations that administered the goods of the local church and elected its priest), confraternities (religious societies for mutual assistance), politico-religious parties bound together by solemn oath-takings, and *consorterie* (‘tower societies’) formed to provide mutual security, were dominant in local affairs.”

in general, nothing like this existed in medieval russia (or eastern europe) — not on this scale anyway — the novgorod republic, which lasted for three centuries and came to an end in 1478, probably being the most notable exception. eastern european society was still very much founded upon the extended family for much of the period (although, again, in certain times and locales that was not the case — russia’s a big place). only a handful of merchants’ guilds were given permission to exist in russia between the fourteenth and eighteenth centuries, and the powers that be (including the orthodox church) regularly suppressed craftsmen’s guilds [pg. 13]. by contrast, northern italy was full of civic-mindedness already by the high middle ages.

meanwhile, in england (and other parts of northwestern europe) [pgs. 3-4]:

“As a form of voluntary association, bound by oath and by a (usually modest) material subscription, the fraternity or guild was widespread in late-medieval England and continental Europe. Both the ubiquity and the frequency of the form have been underlined by recent historical case-studies. While the particular purpose and activities of a fraternity might be infinitely various, the organization may be characterized in general as combining pious with social, economic, and political purposes. Its declared aims invariably included important religious functions, expressed in the invocation of a saintly patron and an annual mass with prayers for deceased members. With equal certainty, the annual feast day would bring the members together for a drink or a meal to celebrate their community. The overwhelming majority of English guilds admitted women alongside men: a feature generally characteristic of guilds of medieval northern Europe, although not so prevalent in the Mediterranean world. Sometimes described in modern English accounts as ‘parish fraternities’, these clubs indeed were often founded by groups of parishioners and regularly made use of an altar in a parish church as a devotional focus; yet they as often drew their memberships from a wider field than that of the parish, whose bounds they readily transcended…. An individual might join more than one guild, thereby extending still futher the range of his or her contacts. A significant minority of fraternities crystallized around a particular trade…. The overwhelming majority of guilds, however, were not tied by such association to a single craft, but brought together representatives of various trades and professions.”

extraordinarily, one type of fraternity — of non-kin remember (the whole point of voluntary associations is that they’re made up of non-kin) — appeared in england as early as the late-800s. from a previous post, the importance of the kindred in anglo-saxon society:

“the *gegildan* appears in some of the anglo-saxon laws in the late-800s as an alternative group of people to whom wergeld might be paid if the wronged individual had no kin. by the 900s, though, in southern england, the gegildan might be the only group that received wergeld, bypassing kin altogether. from Wage Labor and Guilds in Medieval Europe [pgs. 39-42]:

“‘The laws of King Alfred of Wessex, dated to 892-893 or a few years earlier, are more informative about the *gegildan*. Again, the context is murder and the wergild — the compensation required for the crime. By Alfred’s time, if not during Ine’s, the *gegildan* is clearly a group of associates who were not related by blood. The clearest example of this is in chapter 31 of the laws: ‘If a man in this position is slain — if he has no relatives (maternal or paternal) — half the wergild shall be paid to the king, and half to the *gegildan*.’ No information exists on the purpose of the *gegildan* other than its role as a substitute for kinship ties for those without any relatives. These associates, who presumably were bound together by an oath for mutual protection, if only to identify who was responsible, would benefit anyone, whether the person had relatives or not…. Although the evidence from the laws of Ine may be read either way, the *gegildan* seems to be an old social institution. As seen more clearly in the tenth and eleventh centuries, it acquired additional functions — a policing role and a religious character.

“‘The nobles, clergy, and commoners of London agreed upon a series of regulations for the city, with the encouragement and approval of King Athelstan, who caused the rules to be set down some time in the late 920s or 930s. The primary purpose of these ordinances was to maintain peace and security in the city, and all those supporting these goals had solemnly pledged themselves to this *gegildan*. This type of inclusive guild, sometimes referred to as a peace guild, was an attempt to create one more additional level of social responsibility to support the king and his officials in keeping the peaces. This social group of every responsible person in London is a broad one, and the law does not use the term *gegildan* to describe the association in general….

“‘The idea of a guild to keep the peace was not limited to London, and a document from the late tenth century contains the rules and duties of the thegn‘s guild in Cambridge. This guild appears to have been a private association, and no king or noble is mentioned as assenting to or encouraging this group. Most of the rules concern the principle purposes of this guild — the security of the members, which receives the most attention, and the spiritual benefits of membership itself. The guild performed the tasks of the old *gegildan*: the members were obliged to defend one another, collect the wergild, and take up vengeance against anyone refusing to pay compensation. The members also swore an oath of loyalty to each other, promising to bring the body of a deceased member to a chosen burial site and supply half the food for the funeral feast. For the first time, another category of help was made explicit — the guild bound itself to common almsgiving for departed members — and the oath of loyalty the members swore included both religious and secular affairs. Although in many respects this guild resembles a confraternity along the lines Hincmar established for the archdiocese of Rheims, the older purpose of the group — mutual protection with its necessary threat of vengeance — makes the Anglo-Saxon guild something more than a prayer meeting. To include almsgiving to members in distress would be a small step, given the scope of activities this guild established. There is no sign that the thegns cooperated in any economic endeavors, but older rules of rural society had already determined methods of sharing responsibility in the villages, and the thegns cooperated on everything that was important in their lives. The thegns of Cambridge had a guild that resembles in some important ways the communal oath, that will be discussed below, of some Italian cities in the next century.'”

the gegildan of early medieval england, then — a voluntary association, a fraternity — appeared on the scene something like two hundred years before the communes of northern italy arose, three hundred plus years before the novgorod republic was formed, and nearly nine hundred years before the russians gave civiness another shot (after novgorod). i’m not aware of any earlier such associations in western medieval europe, although they may have existed. it appears, too, that the gegildan appeared in situ in england, a newly developed social structure to take over some of the earlier functions of the rapidly disappearing kindred (including feuding and protection), although maybe the concept was imported from the carolingians — the heart of the preceding frankish kingdoms, austrasia, was where manorialism had begun, which was then imported across the channel, so perhaps the gegildan concept was as well.

whatever the case, it’s in the core of “core” europe, once again, that we find the earliest evidence for behavioral patterns that are now the hallmarks of western civilization: late marriage and nuclear families, lowest levels of cousin marriage for the longest period of time, low levels of violence, high levels of civic-mindedness (see above), universalism, unparalleled accomplishment — they all appear earliest (in medieval europe), and are still the strongest, in this central area (very roughly the area indicated by the green oval on this map).

so, now we come to it: why? why was it “evident” by the end of the nineteenth century that there were two europes, and what do all these long-standing historical differences have to do with it?

the ultimate cause must lie in our biologies. humans are biological creatures, so there’s no way around it. we know that all behavioral traits are heritable, so we have to look to differences in the populations’ genetics and evolutionary histories.

as i wrote recently: evolution in humans is ongoing, recent, can be pretty rapid (within some constraints), and has been/is localized (as well as global). in fact, human evolution has sped up since the agricultural revolution since the number of individuals, and therefore mutations, on which natural selection might work skyrocketed in post-agricultural societies. remember, too, that “every society selects for something,” and that we’re talking about frequencies of genes in populations and that those frequencies can fluctuate up and down over time.

so there is NO reason NOT to suppose that the differences in behavioral traits that we see between european sub-populations today — including those between western and eastern europe — aren’t genetic and the result of differing evolutionary histories or pathways.

even rapid evolution takes time, though. we’re not talking one or two generations, but more like thirty or forty — fifty’s even better. point is, evolutionary changes don’t only occur on the scale of eons. they can also happen over the course of centuries (again, multiples of centuries, not just one or two). the circa eleven to twelve hundred years since the major restructuring of society that occurred in “core” europe in the early medieval period — i.e. the beginnings of manorialism, the start of consistent and sustained outbreeding (i.e. the avoidance of close cousin marriage), and the appearance of voluntary associations — is ample time for northwestern europeans to have gone down a unique evolutionary pathway and to acquire behavioral traits quite different from those of other europeans — including eastern europeans — who did not go down the same pathway (but who would’ve gone down their own evolutionary pathways, btw).

what i think happened was that the newly created socioeconomic structures and cultural (in this case largely religious) practices of the early medieval period in northwest “core” europe introduced a whole new set of selective pressures on northwest europeans compared to those which had existed previously. rather than a suite of traits connected to familial or nepostic altruism (or clannishness) being selected for, the new society selected for traits more connected to reciprocal altruism.

before the early medieval period, northwest europeans — looking away from the urbanized gallo-romans who may have been something of a special case (more on them another day) — had been kin-based populations of agri-pastoralists whose societies were characterized by inter-clan feuding, honor/shame (vs. integrity/guilt), and particularism (vs. universalism). i think these traits were under constant selection in those populations because: reproductive success in those societies was dependent upon one’s connection to, and one’s standing within, the extended kin-group, so, thanks to being tied to kin rather than non-kin, nepotistic altruism genes would’ve been favored over reciprocal altruism ones; the extended kin-group was the element within which most individuals would’ve interacted with others, those others being related individuals who would’ve been likely to share the same nepotistic altruism genes (alleles) [see here for more]; and cousin marriage was rife, which again would’ve further fuelled the selection for these genes, since members of the same kin-group would’ve had an even greater likelihood of sharing the same versions of their nepotistic altruism genes.

pretty much the opposite happened during the early and high middle ages in “core” europe. manorialism pushed for nuclear families rather than extended family groupings, and so people began to interact more with non-kin rather than kin, enabling the selection for more traits related to reciprocal altruism. the avoidance of close cousin marriage meant that family members would’ve shared fewer altruism genes in common, so any selection for nepotistic altruism would’ve slowed down. and once voluntary associations of non-kin appeared, the selection for reciprocal altruism really would’ve (or, at least, could’ve) taken off. reproductive success was no longer dependent upon connections to the extended family group, but, rather, unrelated individuals living with the community.

the manor system developed in the 500s in “core” europe (austrasia), but did not arrive in russia (and much of eastern europe) until the late medieval/early modern period. (it never got to the balkans.) the extended family was most likely gone on the manors in the west by the 800s (see mitterauer), although it is conceivable that the nuclear families found on the manors in the earliest days were residential nuclear familes rather than the fully atomized ones that we see in the west today. certainly by the 1500s, there are no longer any traces of the extended family among “core” europeans (although there are still some pockets). the avoidance of cousin marriage was underway in earnest by the 800s (possibly earlier, but definitely by the 800s). it was still on shaky ground as late as the 1400s in russia. and, as we’ve seen, voluntary associations appeared very early in “core” western europe, but only very recently in russia (and, presumably, other areas of eastern europe).

most of you will recognize this as the hajnal line story (yet again!) with a few new nuances thrown in. manorialism, outbreeding, and voluntary associations all began in “core” europe — again very roughly the area outlined by the green oval on the map below (the other lines indicate, again roughly the extent of the hajnal line) — and they spread outwards from there over time, eventually reaching russia and other parts of eastern europe, but not until very late. (and the manor system in russia, once it was adopted there, was of a very different form than what had existed in western europe.)

hajnal line - core europe

inside the hajnal line, which (imo) reflects the extent of the strongest selection for behavioral traits related to reciprocal altruism over nepotistic altruism, the populations have stronger democratic traditions, are more civic-minded, are less corrupt, and score higher on individualism (vs. collectivism) on hofstede’s idv dimension than the populations outside the hajnal line. (please, see my big summary post on the hajnal line for more details.) all of these behavioral patterns “fit” better with the idea that these populations are characterized by innate reciprocal altruism tendencies rather than more nepotistic altruism ones. the populations outside the hajnal line seem to be more oppositely inclined.

there is no doubt that soviet communism wreaked havoc on eastern european populations. some untold millions died in the gulags, families and towns and villages were ripped apart, political repression was beyond belief. but smart money says that, along with civicness, many of the “non-western” features of contemporary eastern europe — high corruption rates, etc. — have deeper roots, and are not the consequences of communism, but rather of recent evolution by natural selection.

(note: comments do not require an email. sorry there’s no tl;dr summary!)

i’ve been trying to think through polygamy and if there’s any potential there for the selection for clannishness like i think there is with long-term cousin marriage. (i think i might have sprained a parietal lobe while doing so. (*^_^*) ) i very much have subsaharan african societies in mind here, but, of course, polygamy occurs elsewhere, too.

on the surface it seems obvious that long-term polygamy ought to set the stage for the possible selection for clannish behaviors like cousin marriage (imho) does. like repeated cousin marriage, strict polygamy ought to narrow the relatedness within a population — the result of strict polygamy should be a greater number of half-siblings in a population than in a randomly-mating population, and, of course, half-siblings are more closely related to one another than non-siblings, so a society full of half-siblings could potentially lead to an accelerated selection for nepotistic altruism in a way similar to cousin marrying societies.

however, one big difference is that in polygamous societies generally — even in subsaharan african societies (where there’s a lot of polygamy) — people do not marry/mate with their half-siblings. (it does occasionally happen in some subsaharan societies, but only occasionally.) so, unlike in cousin-marriage societies, “genes for nepostistic altruism” (whatever they might be) might *not* become concentrated in family lineages. yes, there are a lot of half-siblings in polygamous societies, but any particular nepostistic altruism (“clannishness”) genes they might have (gotten from their fathers) will get diluted as they move out into the general population and marry non-relatives. if polygamy isn’t a driver of accelerated selection for nepotistic altruism (and i’ve rather persuaded myself that it isn’t), that could explain why subsaharan africans are generally pretty civic-minded, comparatively speaking. (the poor outcomes seen in african nations are perhaps more the result of other factors like low iq, high disease rates, etc., rather than clannishness. dunno. Further Research is RequiredTM.)

i should note here that polygamy in subsaharan africa is extremely variegated — in some societies, it’s typical for the first wife to actually be a cousin, and then the rest not. so there can be a layer of cousin marriage in amongst the polygamy. in other societies, cousin marriage is completely avoided. in yet other societies, the series of wives might be sisters (sororal polygyny), which makes all the offspring not only half-siblings (because they have the same father) but also cousins (because their mothers are sisters). here you would think that any selection for nepotistic altruism should very much be amplified. of course, in many subsaharan african societies — especially the polygamous ones — there’s often a lot of hanky-panky going on, so not all of the siblings will truly be half-siblings, etc. that’ll dilute your genes for nepotistic altruism right there.

another thing i also thought of regarding subsaharan and/or polygamous societies is the fact that all of the half-siblings don’t always grow up together. in patrifocal polygamous societies, yes — there you’ll have one man living with all of his wives (poor fellow!) and all of his kids, so all the half-siblings will be raised in the same place and interact with one another — and, presumably, continue to do so as adults. in matrifocal societies, a mother and her children reside with the mother’s family, not her husband and his family. this occurs in some polygamous societies, too.

it seems to me that, even if polygamy was a driver of accelerated selection for nepotistic altruism, such selection couldn’t possibly happen if the carriers of the clannishness genes don’t interact. if the half-siblings from polygamous unions don’t grow up together, or don’t interact much as adults, but rather with their (ordinary, i.e. not inbred) cousins, how would clannishness be selected for? it wouldn’t, i don’t think. or it wouldn’t be selected for in an amplified, accelerated way (which is what i think happens in the long-term cousin marriage scenario).

and that’s as far as i got with thinking through polygamy (i shall return to this topic, i’m sure). but thinking about the patrifocal vs. matrifocal family types got me to thinking about something else.

thought experiment: let’s say you eliminate cousin marriage from a population, but don’t eliminate the extended family. say you get rid of the inbreeding, but individuals continue to interact mostly with their close (extended) family members — more so than with the other members of society who are unrelated to them. you would think that it would take longer for clannishness to disappear — for “genes for nepostistic altruism” to get diluted in the population — than in a society where both cousin marriage AND the extended family were simultaneously eliminated.

i am, of course, talking about medieval western versus eastern europe here. the extended family was eliminated quite early in the middle ages in western europe via manorialism along with cousin marriage (serious changes to both were well underway in western europe by the 800s). in eastern europe, the cousin marriage bans appeared later simply because christianity had arrived later. and, especially the further east one goes (like into russia), the fewer pressures there were to eliminate the extended family. quite the opposite, really. for example, this was the situation in the baltic regions, including belorussia, in ca. the fifteenth century [pg. 440]:

a “…’kinship holding’, was collectively held by the extended family. Rural settlements often contained more than one kinship holding, and each holding was in turn subdivided among smaller households within the extended family….”

and in russia as late as the late seventeenth and early eighteenth centuries [pg. 444]:

“Russian manorialism was distinctive in several important ways…. In Russia…it was the peasant commune that allocated these taxes and obligations among the households. The village commune in Russia had emerged in the late seventeenth or early eighteenth centuries in response to increasing demands from the state and the landowning elite; peasant communes not only allocated obligations, but also chose their officials, held court, selected recruits for conscription levies, and kept written records of their activities. The communal clerk was sometimes the only member of his commune who could read and write….

“[O]n Russian manors, where hired labour was often not available, the peasant family had to personally perform labour obligations at the same time that it worked its own farm. This required large, often multi-generational, households with enough labour capacity to serve the simultaneous needs of both the manorial economy and the family farm…. As Steven Hoch has shown, however, life in the large household was hardly a rural idyll; household patriarchs formed a communal elite that ruled with despotic brutality, ruthlessly exploiting their families and denying any autonomy to the adults under them. At the same time, however, the large household also protected the peasant family from ruin.”

(hmmm. ever wonder where the russian love for [left-wing] authoritarianism comes from?)

even if eastern europeans/russians began to avoid cousin marriage around, say, 1000 (conversion to christianity), they didn’t quit residing in extended families and mostly interacting with their extended family members until, like, yesterday. (again, this pattern appears to be more pronounced the further east one travels.) so the dilution of nepotistic altruism genes in eastern european populations — via nepotistic behaviors being misapplied to individuals not sharing the same altruism genes (i.e. unrelated individuals) — didn’t happen as quickly as it did in western europe where people began regularly interacting with non-kin much earlier in the middle ages.

family types matter.

that’s all i’ve got for you for now. more soon! (^_^)

oooooooohhhhhhhh! from Reimagining Europe: Kievan Rus’ in the Medieval World, 988-1146 [pgs. 58-60]:

“The medieval period pre-1215 was an especially interesting time in the history of consanguinity legislation because during this era the church stretched consanguinity to seven degrees, an increase from the four that was common in the late Roman world, and the degrees were calculated in a new manner. Instead of siblings being related in two degrees, as was held previously, the new method of calculation made siblings related in the first degree. This may at first appear to be a small change, but in fact it was enormous. The original method, and the one returned to after the Fourth Lateran Council in 1215, was to count connections between people; thus, for siblings, one degree up to the shared parent, and one degree down to the sibling, for a total of two degrees. For first cousins, a more likely target for marriage than siblngs, it was one degree up to your parent, another degree up to your grandparent, a degree down to your uncle/aunt, and a degree down to your cousins, resulting in a relationship of four degrees.

“The new method of calculating consanguinity was based on degrees to a common ancestor, which resulted in a one-degree relationship for siblings (a common ancestor is one generation back) and two degrees for a cousin (a common ancestor is two generations back). When this concept was applied to seven generations of ancestors, it expanded the pool of consanguineous relations to anyone with whom one shared a great-great-great-great-great-grandparent….

“The Orthodox Church, like the church in Rome, also maintained a policy against consanguineous marriages. Marriages were also forbidden in the seventh degree, but the Orthodox Church never changed its method of calculating degrees, which created a much smaller pool of consanguineous relations.”

oooooooohhhhhhhh! why didn’t they say so in the first place?! =P

so, what this means is, all those cousin marriage regulations out to the “seventh degree” which we hear about from eastern europe (re. orthodox populations)…they’re just referring to SECOND cousins, not SIXTH the way that western european experienced it for a couple hundred years in the medieval period (from about 1000 to 1215). that’s not to say that most medieval western europeans somehow managed to obey the bans out to sixth cousins, but just that there’s apparently never been the same extreme push against close kin marriage in eastern europe. interesting.

from “Marriage Causes in Late Medieval Sweden: The Evidence of Bishop Hans Brask’s Register (1522-27)” in Regional Variations in Matrimonial Law and Custom in Europe, 1150-1600 [pg. 240], on consanguineous marriage in sweden in the sixteenth century:

“Considering the number and type of cases, the Swedish may have been somewhere in between the ‘incestuous’ late-medieval Netherlands, discussed by Vleeschouwers-Van Melkebeek, the carefree Poles described by Brozyna and the English and Parisians who, according to the of Helmholz and Donaghue, had internalized the rules of incest better and did avoid matrimony with relatives. Perhaps ordinary Swedish peasants in the see of Linköping had easier access to dispensations. Possibly the control of the impediment of consanguinity before the voluntary ecclesiastical solemnization also managed to unearth the ties of kinship between fiances. Moreover, the children’s later loss of inheritance rights may have been a risk some couples were unwilling to take if they were discovered to have known about the impediement prior to their marriage. Swedish synodal statues stressed that children born to couples whose marriage was later discovered to be incestuous would only be considered legitimate if their parents had solemnized *in facie ecclesiae* and the banns had been read without opposition.”

most of this picture fits what i’ve been saying: that (some of) the french and english were the earliest adopters of outbreeding in europe (i posted about donahue’s studies here), the scandinavians came to the party a bit later, and eastern europeans (the example in the excerpt above, the poles) much later. i don’t know who these “‘incestuous’ late-medieval” netherlanders were — i’ve been under the impression that the dutch (minus the frisians) are some of the long-term outbreeders along with the french and english. the source for this is: “Incestuous Marriages: Formal Rules and Social Practice in the Southern Burgundian Netherlands” by monique vleeschouwers-van melkebeek in Love, Marriage, and Family Ties in the Later Middle Ages, which is not available on google books at the moment. (dr*t!) what’s not clear to me is whether vleeschouwers-van melkebeek looked at netherlanders in general or just the aristocracy (which these studies often do). i shall have to find out!

from Jews Against Zionism: The American Council for Judaism, 1942-1948 [pg. 23]:

“Antagonism between the established, well-to-do German Jews and the new, working-class East European immigrants was unavoidable. To the East Europeans, the German Jews, whom they called *Yahudim*, were not authentic Jews; their Reform Judaism was a sham. They seemed to lack a feeling of closeness to fellow Jews. The native German Jews, on the other hand, frightened by the ‘Russian invasion,’ tended to regard the new immigrants as primitive, ‘medieval,’ clannish, Asiatic, unrefined, and radical. German Jews even coined the word *kikes* for the Eastern Europeans.”

from The Jews of Chicago: From Shtetl to Suburb [pgs. 95-96]:

“The German Jews…embarked on an extensive program of financing and running a number of educational, health, and social-service institutions, mostly in the Maxwell Street areas. These proved very helpful to the poorer Eastern European immigrants. Socially, the German Jews kept apart from the newer immigrants, living separately and maintaining their own clubs, synagogues, fraternal organizations, and community centers, at which the Eastern European Jews were not welcomed. Later, as the Eastern European Jews progressed, they built a parallel set of their own institutions, such as a hospital, old peoples’ homes, charities, and orphanages. Although the distinction between the two groups was gradually blurred, for decades the social distance between the groups remained great. The German Jews, for example,

“‘did not wish to have these Jews to close to them. These Russians were all right — of that they were quite certain — but, like the southern Negro, they had to keep their place. All sorts of philanthropic enterprises were undertaken in their behalf, but in the management of these enterprises the beneficiaries were given no voice. Charity balls by the debutantes of the German-Jewish elite in behalf of the wretched West Side Jews were held at the splendid clubs of the German Jews, which by this time had increased to four, and charitably inclined young Jewish men and ladies-bountiful spent their leisure hours in alleviating the hardships of the Jewish slum dwellers.

‘But the Russians did not take altogether willingly to the American ways of dispensing *zdoko* (charity). They were accustomed to assisting one another in the Old Country in much more informal style. The Jewish communities they had known in Russia were self-sufficient large families. These German Jews of the ‘societies’ asked all sorts of embarassing questions before they dispensed their financial and other aid. They made investigations and kept records. Most of all, they did not understand — they did not know — their own people; in fact, they were only halfway Jews; they did not even understand *mama loshon* (the mother-tongue), or Yiddish.'”

Quick Questions for Peter and Rosemary Grant“There is widespread misunderstanding about evolution; that it occurs extremely slowly and therefore cannot be studied in a person’s lifetime. This was the view of Charles Darwin. Many biologists and others now know that this is not correct…. The idea that animals as large as birds might evolve before our eyes is not so well known, yet our study in the entirely natural world of Daphne Major island has revealed this does in fact happen when there is a change in the environment, and it takes place over a period as short as a year, and repeatedly.” – h/t billare!

Natural selection and infectious disease in human populations“The ancient biological ‘arms race’ between microbial pathogens and humans has shaped genetic variation in modern populations, and this has important implications for the growing field of medical genomics. As humans migrated throughout the world, populations encountered distinct pathogens, and natural selection increased the prevalence of alleles that are advantageous in the new ecosystems in both host and pathogens. This ancient history now influences human infectious disease susceptibility and microbiome homeostasis, and contributes to common diseases that show geographical disparities, such as autoimmune and metabolic disorders.”

High genetic differentiation between populations often driven by classic selective sweeps“‘We demonstrate that while sites of low differentiation represent sampling effects rather than balancing selection, sites showing extremely high population differentiation are enriched for positive selection events and that one half may be the result of classic selective sweeps. Among these, we rediscover known examples, where we actually identify the established functional SNP, and discover novel examples including the genes ABCA12, CALD1 and ZNF804, which we speculate may be linked to adaptations in skin, calcium metabolism and defense, respectively. Conclusions: We have identified known and many novel candidate regions for geographically restricted positive selection, and suggest several directions for further research.'” – @dienekes’.

The mutation, called A111T, is found in virtually everyone of European ancestry. A111T is also found in populations in the Middle East and Indian subcontinent, but not in high numbers in Africans.

Good Fences: The Importance of Setting Boundaries for Peaceful Coexistence“Switzerland is recognized as a country of peace, stability and prosperity. This is surprising because of its linguistic and religious diversity that in other parts of the world lead to conflict and violence. Here we analyze how peaceful stability is maintained. Our analysis shows that peace does not depend on integrated coexistence, but rather on well defined topographical and political boundaries separating groups, allowing for partial autonomy within a single country. In Switzerland, mountains and lakes are an important part of the boundaries between sharply defined linguistic areas. Political canton and circle (sub-canton) boundaries often separate religious groups. Where such boundaries do not appear to be sufficient, we find that specific aspects of the population distribution guarantee either sufficient separation or sufficient mixing to inhibit intergroup violence according to the quantitative theory of conflict. In exactly one region, a porous mountain range does not adequately separate linguistic groups and that region has experienced significant violent conflict, leading to the recent creation of the canton of Jura.”

How a Protestant spin machine hid the truth about the English Reformation“It seems that in 1533, the year of Henry’s break from Rome, traditional Catholicism was the religion of the vast majority of the country. And in most places it was absolutely thriving. It had developed a particularly English flavour, with a focus on the involvement of ordinary people in parish churches, village greens, plays, and pageants – much of which seemed to involve a good deal of community parties, dancing, and drinking. It is true that English religion in the early 1500s was not especially studious or erudite. The people did not spend hours a day in biblical studies, contemplation, and moralising in the manner of the more intense European reformers. But England had a nationally cohesive spirituality that was alive and exuberant, with a distinctly community feel…. The conclusion of this modern grassroots scholarship is that bulldozing the Catholic Church off the face of medieval England was not a ‘bottom up’ revolution in which Henry merely acquiesced to his people’s wishes by throwing off a widely hated foreign domination. To the contrary, it looks increasingly like Henry and his circle imposed the Reformation ‘top down’, unleashing 100 years of deep anger and alienation that was only overcome by sustained politicking and ruthless force.” – h/t william briggs!

Svante Paabo talk at NIH“According to Dr. Paabo, Ust-Ishim has longer Neandertal chunks than modern humans and this can be used to estimate that the admixture with Neandertals happened 331+/-99 generations before its time of 45,000y BP, or around 50-60,000y BP…. This pretty much proves that there were modern humans in Eurasia before the Upper Paleolithic revolution and disproves Richard Klein’s theory that modern humans together with UP technologies spread Out-of-Africa only after 50,000 years ago.” – from dienekes.

Europeans have three times more Neanderthal genes for lipid catabolism than Asians or Africans“Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans.

The really old Europe is mostly in Eastern Europe“‘These results confirm Sardinia as a refuge area where ancestry related to Early European Farmers has been best preserved, and also the greater persistence of WHG-related ancestry in present-day Eastern European populations.

More on Deafness“Seems to me that limited verbal stimulation is not a very plausible primary cause of low test scores and low academic achievement in blacks, because the degree of deprivation needed to cause a 1-standard deviation decline is extreme (deafness), and because there is an even greater depression of nonverbal scores, which, judging from the results in deaf children, should not be affected at all by limited verbal stimulation.” – from greg cochran.

Whole genome sequencing of six dog breeds from continuous altitudes reveals adaption to high-altitude hypoxia“To understand the genetic bases of adaption to high altitude in dogs, we performed whole-genome sequencing of 60 dogs including five breeds living at continuous altitudes along the Tibetan plateau from 800 to 5,100 m as well as one European breed…. Comparison of the breeds from different altitudes reveals strong signals of population differentiation at the locus of hypoxia-related genes including endothelial Per-Arnt-Sim (PAS) domain protein 1 (EPAS1) and beta hemoglobin cluster. Especially, four novel non-synonymous mutations specific to high-altitude dogs are identified at EPAS1, one of which occurred at a quite conserved site in the PAS domain. The association testing between EPAS1 genotypes and blood-related phenotypes on additional high-altitude dogs reveals that the homozygous mutation is associated with the decreased blood flow resistance, which may help to improve hemorheologic fitness. Interestingly, EPAS1 was also identified as a selective target in Tibetan highlanders, though no amino acid changes were found. Thus, our results not only indicate parallel evolution of humans and dogs in adaption to high-altitude hypoxia, but also provide a new opportunity to study the role of EPAS1 in the adaptive processes.” – h/t joe pickerell!

The relationship between Microcephalin, ASPM and intelligence: A reconsideration“Microcephalin is strongly associated with DNA repair, which indicates a special role for this allele in the intrinsic anti-viral immune response.

Life on Earth may have developed below rather than above ground, reveal scientists“Scientists have now discovered microbes living and reproducing as deep as 5km (3.1 miles) below ground and studies have shown that they are likely to have survived in complete isolation from the surface biosphere for millions and perhaps even billions of years. One of the latest studies into the deep biosphere has found that these microbes form a distinct subsurface community of genetically similar individuals despite living on opposite sides of the world. This global similarity of such an isolated life-form suggests that they may have evolved directly from a common ancestor that lived as long ago at the period when life on earth originated, some 3.5 billion years ago.”

Western scrub-jays allocate longer observation time to more valuable information“When humans mentally reconstruct past events and imagine future scenarios, their subjective experience of mentally time travelling is accompanied by the awareness of doing so.

Thus, the jays can collect information to solve a future problem. Moreover, they can differentiate sources of information according to their potential value and modify behaviour to efficiently collect important, usable information. This is the first evidence of metacognition in a species that passes the behavioural criteria for both retrospective and prospective mental time travel.”

Diet rapidly and reproducibly alters the human gut microbiome“[S]hort-term consumption of diets composed entirely of animal or plant products alters microbial community structure and overwhelms inter-individual differences in microbial gene expression. The animal-based diet increased the abundance of bile-tolerant microorganisms (Alistipes, Bilophila and Bacteroides) and decreased the levels of Firmicutes that metabolize dietary plant polysaccharides (Roseburia, Eubacterium rectale and Ruminococcus bromii). Microbial activity mirrored differences between herbivorous and carnivorous mammals, reflecting trade-offs between carbohydrate and protein fermentation. Foodborne microbes from both diets transiently colonized the gut, including bacteria, fungi and even viruses. Finally, increases in the abundance and activity of Bilophila wadsworthia on the animal-based diet support a link between dietary fat, bile acids and the outgrowth of microorganisms capable of triggering inflammatory bowel disease. In concert, these results demonstrate that the gut microbiome can rapidly respond to altered diet, potentially facilitating the diversity of human dietary lifestyles.”

well! i’m making progress on reading avi tuschman‘s very interesting Our Political Nature: The Evolutionary Origins of What Divides Us [see previous post] — ’bout halfway through now (on chapter 11 out of 23). it’s not actually a difficult book to read, it’s just that real life keeps getting in the way of my virtual one (d*mnit, i hate when that happens!).

tuschman is interested in finding out the personality and behavioral traits underlying liberal and conservative political orientations AND the evolutionary bases for those traits. i’m all for that!

while he does draw on all sorts of research into the differing personality/behavioral traits of liberals and conservatives — and those interested in hbd will be familiar with most of them, like for instance that conservatives tend to be more religious — the main framework that tuschman bases his ideas upon is robert altman’s bob altemeyer‘s “right-wing authoritarianism (RWA)” personality theory, a whole construct that, up until the other day, i knew nothing about. you can read all about the RWA scale on wikipedia.

here from tuschman [chapter 5 – my emphases]:

“Altemeyer’s test consists of thirty controversial statements. Figure 10 breaks down the content of these statements into six categories. Each bar represents one of these content categories and shows the percentage of the thirty statements that makes reference to it.

tuschman - figure 10

“The six content categories, in turn, can be lumped into three larger groups: the grey cluster, the black cluster, and the white cluster. The three categories within the grey cluster are ethnocentrism, religiosity/group morality, and sexual tolerance. These are the three elements that comprise the ‘tribalism‘ cluster of personality traits.

“The two categories in the black cluster measure tolerance of inequality: the first concerns attitudes toward inequality and authority in society, while the second category pertains to inequality and authority within the family.

“The white personality cluster has only one category, which measures perceptions of human nature.”

these three larger groups — tribalism, tolerance of inequality, and perceptions of human nature — are the foundations of tushman’s “personality argument”:

“Human political orientation across space and time has an underlying logic defined by three clusters of measurable personality traits. These three clusters consist of varying attitudes toward tribalism, inequality, and different perceptions of human nature.

“These three factors correspond, of course, to the grey, black, and white color groups in figure 10. To go into slightly greater detail:

– Tribalism. Tribalism breaks down into ethnocentrism (vs. the opposite force, xenophilia, which means an attraction to other groups), religiosity (vs. secularism), and different levels of tolerance toward nonreproductive sexuality.

– Tolerance of Inequality. There are two opposing moral worldviews toward inequality; one is based on the principle of egalitarianism, and the other is based on hierarchy.

– Perceptions of Human Nature. Some people see human nature as more cooperative, while others see it as more competitive.”

most of the book is devoted to looking in depth at these three factors and how their various facets correspond to either liberal or conservative personalities. tuschman’s approach is very systematic (i like it a lot!): one section (containing several chapters), for instance, deals with how the different feelings of tribalism play out in human societies, and then the following section (also containing several chapters) deals with the likely/possible evolutionary underpinnings of those feelings/behaviors. this format is repeated for all three factors.

i’ll probably discuss some of these factors — and what tuschman has to say about them — individually in later posts (don’t want to discuss them all, though — mustn’t give away the plot of the book! (~_^) ). but first i want to back up for a sec and discuss altemeyer’s right-wing authoritarianism stuff, since tuschman’s framework is primarily based upon that — although, as i said, he does draw a LOT of evidence from other sources as well.

altemeyer’s RWA work (and this is just a hoot to read about!) is based upon the previous work of theodor adorno (frankfurt school), et al., who wanted to find out why some people became nazis (real nazis in wwii). they devised an “f(ascist)-scale” and everything. their work was later heavily criticized. (see also “The Authoritarian Personality.”)


altemeyer’s new-and-improved authoritarianism scale — which, like its predecessor, only focuses on conservatives — apparently has three “clusters” of personality traits which are summarized thusly [chapter 4 — tuschman references altemeyer’s Enemies of Freedom: Understanding Right-Wing Authoritarianism]:

(1) Authoritarian Submission — a high degree of submission to the authorities who are perceived to be established and legitimate in the society in which one lives;

(2) Authoritarian Aggression — a general aggressiveness, directed against various persons, that is perceived to be sanctioned by established authorities; and

(3) Conventionalism — a high degree of adherence to the social conventions that are perceived to be endorsed by society and its established authorities.

heh! well, i’m sorry, but — and this, no doubt, reflects my own somewhat conservative personality and biases — but the first group of people that i thought of on reading that description was today’s politically correct liberals! the militant ones, i mean.

“high degree of submission to authorities who are perceived to be established/legitimate?” who? like st. stephen jay gould? or jared diamond? or richard dawkins? (pardon my focus on academics there, but that is the universe that i inhabit. well, one of them!)

“general aggressiveness, directed against various persons, perceived to be sanctioned by est. authorities?” what? like watsonings? or richwinings? or derbyshearings?

“high degree of adherence to the social conventions?” all of political correctness!

and if we are to think about authoritarianism and politics and the sorts of political regimes that are authoritarian in nature — and supported by the hordes — sure there are right-wing examples like nazi germany and franco’s spain, but what about stalin’s russia and mao’s china?! not to mention east germany (where the stasi chief even had an actual room 101!).

i’m sorry, but i can’t help but think that authoritarianism — including personality types that favor authoritarianism — also occurs on the left. a ten-second google search shows me that left-wing authoritarianism has both been researched and found to exist — something which tuschman, unfortunately, doesn’t mention in the book.

the authors of The Presence of Left-Wing Authoritarianism in Western Europe and Its Relationship with Conservative Ideology found authoritarian traits — measured by willingness to use violence (aggression) and needing to obey left-wing leaders (submission) — in extremist left-wingers in belgium (flemish belgium) in the country’s communist party, but especially in the country’s stalinist(!) party. (interestingly, the members of an anarchist movement in the nation who were studied were not authoritarian in nature.) from the paper:

“The present results suggest the presence of authoritarianism among Western European adherents of extreme left-wing parties. Particularly the adherents of the Stalinist party obtained high LWA scores. So, it seems that we achieved in finding ‘the Loch Ness Monster of political psychology.’ The LWA scale not only proved to be successful in distinguishing anarchists and extreme left-wingers from the other ideological groups (the authoritarian aggression facet is most fruitful for this purpose), but also in distinguishing extreme left-wingers from anarchists (the authoritarian submission facet is most fruitful for this purpose). The discriminatory power to distinguish between left-wing extremists, anarchists, and other ideological groups underscores the validity of the aggression and submission facet scales. However, these results also make it clear that the presence of LWA in Western societies seems to be limited to very specific political movements that do not elicit much support in the mass public.”

the presence of left-wing authoritarianism might be limited in western european societies, but you find much more of it in eastern europe! from Left-wing authoritarianism is not a myth, but a worrisome reality. Evidence from 13 Eastern European countries:

“Using representative samples the relationship between authoritarianism and political preferences was examined in 13 excommunist Eastern European countries. Employing six different indicators of left-wing/communist political orientations made clear that, despite cross-national differences, left-wing authoritarianism is definitely not a myth in Eastern Europe….

“Interesting is also the intra-regional variation regarding the relation between authoritarianism and political ideology.”

i feel a hajnal line map coming on. (~_^)

“In Bulgaria and Russia, for example, authoritarianism is consequently linked with communist/political left-wing preferences regardless of which indicator is used; while in a country like Hungary almost no evidence was found for left-wing authoritarianism. This is in line with Todosijevic and Enyedi’s (2008a) conclusion that leftist authoritarians do exist in Hungary, but they are few and their presence is overshadowed by the authoritarianism of the anticommunist right. Also Enyedi et al. (1997) conclude that the phenomenon of left-wing authoritarianism, though present in Hungary, is less significant than its rightist counterpart….

“[A]uthoritarians in Central and Eastern European countries embrace communist principles and that they hold negative attitudes towards democracy….

“The existence of left-wing authoritarianism has been debated for about six decades. Many authors believed that authoritarianism is essentially a right-wing phenomenon. Most of the evidence comes from studies conducted in Western countries; while the members of the American Communist Part have always been treated as highly deviant (Krugman, 1952). Also Altemeyer (1981) described radical leftists in countries like Canada and the United States as not submissive to established authorities and not conventional. Therefore we believe that the fact that thus far not a lot of evidence is found for left-wing authoritarianism is not due to nonexistence of left-wing authoritarianism, but is due to the fact that we have not looked at the right places.

i’m not sure, yet, what the existence of left-wing authoritarianism — and the fact that tuschman didn’t include it in his book — means for tuschman’s model of our political natures. i need to finish reading the book first — and to think more about it all, too. one thing is certain: i’m more than a bit dubious about using the right-wing authoritarianism model as a basis for looking at the differences between liberals and conservatives. i fear too many things might be missing from that picture, as is evidenced by the two random studies on left-wing authoritarianism that i pulled off the internet.

previously: our political nature and human biodiversity and well this sounds familiar…
