(update 11/07/15: added a map and some comments to the third section below.)

if you’re a wise person who doesn’t fritter away their time on twitter, then you will have missed the short discussion the week before last about communism and east germany which was prompted by this tweet…

as in the convos regarding russia and eastern europe in general which i mentioned in my last post, many tweeps attributed the very high rates of non-religious people in eastern germany versus western to that region’s years under communism. it was, in fact, this debate about east germany which reminded me that i had intended to post about the case of russia and civicness and corruption, etc. (which i then did!), but i wanted to address the matter of eastern germany in a separate post since there are several interesting nuances related to the question of europe’s east-west divide to be uncovered here which are particular to germany/central europe. (or at least i think they’re interesting!). so, here we go…eastern germany, medieval manorialism, and (yes) the hajnal line…

again, just as in the case of russia, in order to try to settle the debate about whether or not communism left any long-lasting effects on the behavioral patterns (and beliefs, in this case) of east germans, i think we should start by asking if there were any similar such differences between east and west germans before the gdr existed. if yes, then i’d say we could pretty quickly rule out the communist state as having been much of an influencing force. at the very least, that premise would start to look pretty shaky. another approach might be to check the actual history: did the powers that be of the gdr actually suppress religious belief during the forty or so years of its existence? let’s look at the latter question first.

the consensus among historians (as much as such a thing can ever exist) appears to be, no — for most of time that the gdr was in existence, the communist authorities were fairly tolerant of christianity under a system known as “church in socialism” (“kirche im sozialismus”). here from Eastern Germany: the most godless place on Earth by peter thompson:

“Different reasons are adduced for the absence of religion in the east. The first one that is usually brought out is the fact that that area was run by the Communist party from 1945 to 1990 and that its explicit hostility to religion meant that it was largely stamped out. However, this is not entirely the case. In fact, after initial hostilities in the first years of the GDR, the SED came to a relatively comfortable accommodation with what was called the Church in Socialism. The churches in the GDR were given a high degree of autonomy by SED standards and indeed became the organisational focus of the dissident movement of the 1990s, which was to some extent led by Protestant pastors.”

while it’s true that religious education was banned in schools, theology faculties remained open at the major universities — although spies were deployed into those departments (like everywhere else, i suppose). but, also…

“…the Protestant Youth Committees, with their open-minded and different approach, attracted large numbers of young people from outside the church as well as from within it. The ‘Open Youth Work’ carried on by some pastors was an especially powerful draw for disaffected youths.” [pg. 51]


“Throughout its existence, there was a continuity in the basic policy of the GDR *Kirchenbund* towards the GDR authorities, summed up by the phrase ‘church within socialism’, avoiding the extremes of total assimilation or outright resistance to the policies of the SED [socialist unity party of germany]. The policy was only possible, however, because the GDR authorities themselves were prepared to tolerate the existence of a church which was not fully integrated into the SED dominated system of ‘democratic centralism’…. This created a space for the development of a limited ‘civil society’ and the growth of political disaffection….” [pg. 100]


“[I]n the early years of the GDR the state had made moves to diminish the importance of church festivals by turning days such as Christmas Day and Good Friday into ordinary work days. This meant that only Christians who were prepared to declare their faith in public by asking for special permission for leave could take time off to go to church. The Christmas holidays were turned into ‘New Year holidays’, but more fanciful attempts to blot out Christmas by calling Christmas trees ‘end of year trees’ and the Christ Child the ‘Solidarity Child’ seem to have fallen by the wayside.

“At their midnight services on Christmas Eve, churches were always full. Werner Krusche says he will never forget the cathedral in Magdeburg overflowing, with around 5,000 people coming to the different services, despite the icy cold. Many among them were not even members of the church. ‘Why did they come?’, he asks. ‘Perhaps they themselves didn’t exactly know. Enough that they were there and joined the celebration.'” [pg. 74]

so although the state did exercise a lot of control over the churches in east germany, it didn’t impact much on the religiosity of the populace — at least not according to the historians.

here, however, is more from thompson [my emphasis]:

“Another factor is that religion in eastern Germany is also overwhelmingly Protestant, both historically and in contemporary terms. Of the 25% who do identify themselves as religious, 21% of them are Protestants. The other 4% is made up of a small number of Catholics as well as Muslims and adherents of other new evangelical groups, new-age sects or alternative religions. The Protestant church is in steep decline with twice as many people leaving it every year as joining.”

this brings us back to the first of my questions: were there any similar such differences between east and west germans before the gdr existed? and the answer is: yes, indeed. and precisely in the department of religion! jayman’s also previously pointed out that in the 1920s and 30s (north-)eastern germans voted quite differently than (south-)western germans. now we also have a religious divide — one that goes right back to at least the 1600s. here’s a map of the religious divisions in germany in 1610 (taken from here) on which i’ve attempted (*ahem*) to draw the borders of east germany [click on map to see a LARGER view]:

germany_religious_1610 + east germany border 02

as you can see, in 1610 the vast majority of the population in the area that would centuries later become east germany was protestant (either lutheran or calvinist), and in general protestantism was more prevalent in the northern part of what is today germany than in the south. again, this is very much in accordance with what jayman blogged: that there’s a north-south as well as an east-west divide in germany.

edit (11/07):

following a suggestion by margulon who commented

“One problem with your argument is that whether the reformation took long-term roots in a particular territory was not only decided by the local population within any territory of the Holy Roman Empire, but by the principle ‘cuius regio, eius religio.’ In other words, it was mainly the ruling princely family – members of a supra-regional elite – that decided about the religion in their respective territories according to their respective preferences. This also led to population exchanges of holdouts refusing to convert. I would therefore hesitate to draw conclusions from the predominant religion after 1648 or so.”

…here’s a map of the state of the reformation in germany from earlier in the period — 1560 — with the gdr outlined (roughly!) by me [map source — click on map for LARGER view]:

Confessional Divisions 1560 + east germany

even as early as 1560, then, the region that would become east germany was almost entirely populated by protestants — mostly lutherans, but also some anabaptists. there doesn’t appear to be much of a calvinist population at this point, for whatever reason, unlike by 1610 (the map above). and again, on the whole, the northern parts of what would become germany had greater numbers of protestants than southern germany. the website from which i sourced this map, german history documents and images, says much the same:

“The map shows where the Reformation had been introduced by 1560. The most important areas lay in the Empire’s northern and central zones: Lutheranism in Mecklenburg-Western Pomerania, Brandenburg, Braunschweig-Lüneburg, Hesse, Saxony, and (though outside the Empire’s boundary) Prussia. In the south, Lutheranism was established in Württemberg, parts of Franconia, and numerous Imperial cities. After c. 1580, the Catholic Church experienced a massive revival, which halted the advance of Protestantism and even allowed the old faith to recover some episcopal territories and most of the Austrian lands and the kingdom of Bohemia. Catholicism remained predominant in the western and southwestern portions of the Empire, including most of Alsace and all of Lorraine, as well as Bavaria. The third, Reformed confession spread via Geneva to France, the Netherlands, and some of the German lands. The outcome was a religious geography which survived both the demographic shifts caused by both the Thirty Years War (1618-1648) and the Second World War.”

end edit.

the root cause behind these regional differences is not, i don’t think, simply religious or political or some other set of cultural practices, but rather lies in the recent evolutionary histories of these subgroups. as i said in my last post:

“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.

the “core” of “core” europe was the frankish kingdom of austrasia (from whence the pepinids or carolingians hailed), and this is both where the (bipartite) manor system originated in the 500s and where the avoidance of close cousin marriage (outbreeding) became de rigueur in the 800s. here’s a map indicating (as best as i could manage!) the austrasia of the 400s-800s as well as the much later gdr [click on map for LARGER view]:

westerneurope-physical-map + austrasia + east germany

most of east germany (the gdr) lies outside of the region formerly known as austrasia, as does large parts of both today’s northern and southern germany. southeast germany was incorporated into the frankish kingdom quite early (in the early 500s — swabia on the map below), but both northern germany and southwestern germany much later — not until the late 700s (saxony and bavaria on map). eastern germany, as we will see below, even later than that. the later the incorporation into the frankish empire, the later the introduction of both manorialism and outbreeding. and, keeping in mind recent, rapid, and local human evolution, that should mean that these more peripheral populations experienced whatever selective pressures manorialism and outbreeding exerted for shorter periods of time than the “core” core europeans back in austrasia. here’s a map of the expansion of the frankish kingdoms so you can get yourself oriented [source – click on image for LARGER view]:


in Why Europe?, historian michael mitterauer has this to say about the expansion of the frankish state and the spread of the manor system [pgs. 45-46 – my emphasis]:

“The most significant expansion of the model agricultural system in the Frankish heartland between the Seine and the Rhine took place toward the east. Its diffusion embraced almost the whole of central Europe and large parts of eastern Europe…. This great colonizing process, which transmitted Frankish agricultural structures and their accompanying forms of lordship…”

…not to mention people…

“…took off at the latest around the middle of the eighth century. Frankish majordomos or kings from the Carolingian house introduced manorial estates (*Villikation*) and the hide system (*Hufenverfassung*) throughout the royal estates east of the Rhine as well — in Mainfranken (now Middle Franconia), in Hessia, and in Thuringia…. The eastern limit of the Carolingian Empire was for a long time an important dividing line between the expanding Frankish agricultural system and eastern European agricultural structures. When the push toward colonization continued with more force in the High Middle Ages, newer models of *Rentengrundherrschaft* predominated — but they were still founded on the hide system. This pattern was consequently established over a wide area: in the Baltic, in large parts of Poland, in Bohemia, Moravia and parts of Slovakia, in western Hungary, and in Slovenia. Colonization established a line stretching roughly from St. Petersburg to Trieste….”

i think you all know what that line is by now. (~_^)

“The sixteenth century witnessed the last great attempt to establish the hide system throughout an eastern European region when King Sigismund II of Poland tried it in the Lithuanian part of his empire in what is now modern-day Belarus. The eastward expansion of Frankish agrarian reform therefore spanned at least eight centuries. The basic model of the hide system was of course often modified over such a long period, but there was structural continuity nevertheless.”

here’s a map of the carolingian empire between 843-888 [source] with the gdr (roughly!) indicated. from mitterauer again: “The eastern limit of the Carolingian Empire was for a long time an important dividing line between the expanding Frankish agricultural system and eastern European agricultural structures.” that “eastern limit” is the lilac border on the map, and as you can see something like two-thirds of what would become the gdr lay outside of that border [click on map for LARGER view]:

carolingian empire + east germany

in the earliest days of manorialism — back in austrasia in the 400-500s — manor life was a bit like living on a kibbutz — labor was pooled and everyone ate their meals together in the manor’s great hall. this was a holdover from the roman villa system which was run on the backs of slaves who lived in dormitories and were fed as a group by the owner of the villa. the manor system in core austrasia changed pretty rapidly (already by the 500s) to one in which the lord of the manor (who might’ve been an abbot in a monastery) distributed farms to couples for them to work independently in exchange for a certain amount of labor on the lord’s manor (the demesne). this is what’s known as bipartite manorialism. and from almost the beginning, then, bipartite manorialism pushed the population into nuclear families, which may for some generations have remained what i call residential nuclear families (i.e. residing as a conjugal couple, but still having regular contact and interaction with extended family members). over the centuries, however, these became the true, atomized nuclear families that characterize northwest europe today.

for the first couple (few?) hundred years of this manor system, sons did not necessarily inherit the farms that their fathers worked. when they came of age, and if and when a farm on the manor became available, a young man — and his new wife (one would not marry before getting a farm — not if you wanted to be a part of the manor system) — would be granted the rights to another farm. (peasants could also, and did, own their own private property — some more than others — but this varied in place and time.) over time, this practice changed as well, and eventually peasant farms on manors became virtually hereditary. (i’m not sure when this change happened, though — i still need to find that out.) finally, during the high middle ages (1100s-1300s) the labor obligations of peasants were phased out and it became common practice for farmers simply to pay rent to the manor lords. this is the Rentengrundherrschaft mentioned by mitterauer in the quote above. [see mitterauer for more details on all of this. and see also my previous post medieval manorialism’s selection pressures.]

so here we have some major differences in the selection pressures that western+southwestern versus eastern+northern+southeastern germans would’ve experienced in the early and high middle ages:

– western and southwestern germans of austrasia and swabia (see this map again) would’ve experienced both kibbutz-style and bipartite manorialism from very early on beginning in the 400-500s. contrasted with this, northern (saxony) and southeastern germans (bavaria) wouldn’t have experienced any sort of manorialism until after the late 700s at the earliest — three to four hundred years after the more western germans. so for a dozen or more generations, western germans (some of them would later become the french, of course) were engaged in bipartite manorialism, in which they had to delay marriage (if they wanted to take part in the system), and they were living in nuclear families.

– the region that would one day become east germany (the gdr) didn’t see any manorialism or nuclear families at all until germanic peoples (and some others) migrated to those areas during the ostsiedlung in the high middle ages, at least some six or seven hundred years after the populations in austrasia began experiencing these new selection pressures. and when manors were finally established there, they were based upon the rent system rather than being bipartite.

one important feature of the ostsiedlung — the migration of mostly germanic peoples from the west to central and parts of eastern europe — is that the subgroups of germanics from various regions in the west moved pretty much on straight west-to-east axes:

“As a result, the Southeast was settled by South Germans (Bavarians, Swabians), the Northeast by Saxons (in particular those from Westphalia, Flanders, Holland, and Frisia), while central regions were settled by Franks.”

so, the regions that would eventually become northern and east germany (the gdr) were populated by people not only from saxony (the one on the map above), who were a group late to manorialism and christianity (and, therefore, outbreeding), but also by people from places like frisia (and ditmarsia, iirc). i don’t know if you remember the frisians or not, but they never experienced manorialism. ever. and i suspect that the ditmarsians didn’t, either, but i’ll get back to you on that. (along with the peripheral populations of europe, there are other pockets inside the hajnal line where manorialism was weak or entirely absent, for example in the auvergne.) finally, the slavs (or wends) native to northern and eastern germany would not have been manorialized in the early medieval period, and most likely would’ve still been living in extended family groups, so any incorporation of slavs into communities newly settled by the germans (either by marriage or just direct assimilation of slavic families) would’ve again amounted to introgression from a population unlike that of the austrasian germans.

to conclude, when east germany was eventually settled by germanic peoples in the high middle ages, it was comparatively late (six or seven hundred years after the germans in the west began living under the manor system); the manor system in the region was not of the bipartite form, but rather the more abstract rental form; and the migrants consisted primarily of individuals from a population only recently manorialized or never manorialized. in other words, the medieval ancestors of today’s east germans experienced quite different selection pressures than west germans. so, too, did northern germans on the whole compared to southern germans. these differences could go a long way in explaining the north-south and east-west divides within germany that jayman and others have pointed out.

what does any of this evolutionary history have to do with the fact that eastern germans today are much less likely to be religious than western germans, or that greater numbers of northern germans voted for the nazi party in the inter-war years than southern germans?

in my opinion, the latter question is more easily answered — or speculated about (in an informed and educated sort-of way) — than the first one. since northern germans have a shorter evolutionary history of manorialism and nuclear families and even outbreeding (due to their later conversion to christianity), then they may very well be more clannish, or exhibit more nepotistic altruism, than southern germans who are descended from the austrasian franks. thus, nationalsozialismus — not the most universalistic of political philosophies — might’ve appealed. dunno. Further Research is Required™.

with regard to the religious differences, i’m not sure. but here’s something that i think i’ve noticed which may or may not be relevant. here’s a map of the religious divisions in europe at the time of the reformation (1555 – source) onto which i’ve (sloppily!) drawn austrasia and neighboring neustria which was swallowed up by austrasia early on (486). if you look away from peripheral europe (places like ireland, spain, italy, greece, russia), it looks to me as though the protestant reformation happened in the regions immediately surrounding austrasia/neustria — at least that’s where the protestant movements largely began:

religious divisions of europe map + austrasia

i really don’t know what to make of this, and don’t have much to say about it right now, except to repeat myself: the “core” core europe region of austrasia (+neustria) experienced bipartite manorialism, outbreeding, and small family types for the longest period, beginning as early as the 500s (for the manorialism and small families — 800s for the beginning of serious outbreeding), whereas the regions bordering this “core” core would’ve done so for shorter periods of time (and they saw different forms of manorialism as well). and way out in peripheral europe, these “westernization” selection pressures were present for very, very short periods of time (for instance, manorialism barely arrived in russia in the modern period, and then it was of a very different form from that of western europe). for whatever reasons, the protestant reformation appears to have happened in the middle zone. and the middle zone is where the former east germany lies.

in 1965, john hajnal published his seminal finding that historically the populations of northwest europe were marked by late marriage — many even remained single — with a concomitant low birthrate. populations in eastern europe (and elsewhere) were not. the border between these two zones has become known as the hajnal line. subsequent research has found that other parts of peripheral europe — finland (parts of?), southern italy, the southern part of the iberian peninsula, and ireland — also lie outside the hajnal line:

hajnal line

michael mitterauer, who spent his career studying (among other things) the history of family types and structures from the middle ages and onwards, has connected the hajnal line to both the extent of bipartite manorialism and the western church’s precepts against cousin marriage. according to him, the hajnal line basically indicates where the bipartite manor system was present in medieval europe and where the cousin marriage bans were most stringently enforced — from the earliest point in time.

here on this blog, i’ve been posting about the apparent connection between the hajnal line and a whole slew of behavioral patterns and traits including (but very probably not limited to): family size, iq, human achievement, democratic tendencies, civicness, corruption, individualism (vs. collectivism), and even violence. see this post for more on all that: big summary post on the hajnal line. the primary factor connecting hajnal’s line to all these traits, i think, is the evolutionary histories of the populations found within and outside of the line. the basic outline of those different evolutionary histories is in the post above. “core” europeans and peripheral europeans vary in their average social behaviors thanks to the selective pressures they’ve experienced ever since the early middle ages, and the variances in those social behaviors impact many areas of those societies, from the highest levels of government and industry to everyday interactions between neighbors.

keep in mind that the hajnal line as indicated on the map above is schematic. it is NOT a perfectly straight line. the real border is fuzzy — a gradient, like most distributions of genes are (here’s lactase persistence in europe, for example). Further Research is Required™ to figure out where the border really is. also keep in mind that the hajnal line has no doubt been shifting over time, from west to east mainly, but also to the north and south, with the spread of manorialism from the “core” of core europe. that’s because human evolution can be recent, fairly rapid, localized…and is ongoing!



one issue which i didn’t take into consideration above is the possible effects of the post-wwii migrations on the population structure of east germany. to be honest with you, if it happened after 1066, my knowledge of it is usually kinda vague. (*^_^*) please, feel free to fill me in on the details of the modern migrations in the comments if you think they may have significantly affected the earlier population distributions. a couple of things that i do now know thanks to wikipedia are that: 1) four million germans entered east germany at the end of the war from east of the oder-neisse line; and 2) one quarter of east germans fled to the west between the end of the war and 1961. those are two very substantial migration/self-sorting events. with regard to those coming in from the east, presumably their evolutionary history would’ve been the same or very similar to the one i’ve just outlined for northern and eastern germans — late manorialism, Rentengrundherrschaft, later start of outbreeding, and late appearance of the nuclear family. and with regard to those east germans who fled to the west, given that one quarter migrated over the course of just fifteen or sixteen years, it wouldn’t surprise me if this had some effect on the average characteristics and behavioral traits of the remaining east german population. who left? who was left behind?


jayman tweeted this the other day — these are the cardiovascular mortality rates in european men from 2000:

cardiovascular mortality rates - euro men - 2000

his comment on this map was: “Great variation in the length of time peoples have had to adapt to agro pathogens.” you know what? i think this is exactly right. agro pathogens or, at least, agro something.

beginning in the early medieval period, northwest europe underwent an agricultural revolution. new grain crops were introduced — rye and oats (then, much later, wheat) — as well as some newfangled technological advancements (heavy plow, water mill). all of these spread through northern/western europe via manorialism. (see chapter 1 in mitterauer for more on all this.) i think you can see this dispersal on the map above. maybe.

italy and spain and parts of gaul would’ve grow wheat when they were a part of the roman empire, so those populations have been consuming wheat for quite a long time. they’re in the green with the lowest rates of cardiovascular mortality. the “founder crops” in europe — those that were introduced during the neolithic revolution from the middle east — were emmer (a two-grained spelt), einkorn (one-seeded wheat), barley, and naked wheat. these have been variously consumed in different parts of europe more or less since the neolithic (roughly speaking). the production of rye and oats (and again at a much later point modern wheat) was the mainstay of the manor system, and i think their arrival in different parts of europe is visible on the map above: france (austrasia) where manorialism started has the lowest rate of cardiovascular mortality (plus the population prolly also benefits from its agri-evolutionary history stretching back to roman days); then you see the spread of manorialism (and rye and oats) to the yellow zones — the advancement of the carolingian empire into central europe and also across the channel to southeast england (and to scandinavia?); east germany remains orange since it was manorialized later than western germany (see above post!) — same with northern and western england and ireland (which wasn’t manorialized until something like the 1400s); finally, eastern europe is in the red zone, “manorialized” (barely) very recently.

that looks like a good fit, but, of course, correlation doesn’t mean causation. (~_^)

(note: comments do not require an email. oh noes!)

several people have compared the current migrant crisis in europe to the arrival of the barbarians in rome in the fourth century — for example, here’re steve sailer, peter frost, and historian tom holland. their concern — at least that of steve and peter — is the future of the west: will these migrants (help to) bring down modern western civilization just as the goths et al. did to rome? the question is not just an emotional or an irrational one — migration is one of the main driving forces of evolution (along with things like natural selection and genetic drift), since the movement of individuals from one population to another also means the movement of genes. and because all behavioral traits are heritable, the transference of genes via migration ought to be a matter of interest and importance to one and all. (that’s not to say that it should never be allowed, just that people(s) ought to pay it due attention.)

what i haven’t seen though are any comparisons to a more recent mass migratory event, one which also happened to feature germany, a major player in today’s migrant crisis. i suppose that’s because the whole subject is rather sensitive, but that’s no excuse for ignoring it — rather to the contrary! so, here goes…

in the late-1800s/early-1900s, at least a couple of million (i haven’t been able to find a precise number) eastern european jews migrated to and/or through germany. and how well did that work out for everybody?

from Unwelcome Strangers: East European Jews in Imperial Germany [pgs. 11-12]:

“In the last two years of the 1860s, a few thousand Russian Jews crossed into Prussia seeking relief from cholera epidemics and famines that were wreaking havoc in the western part of the Tsarist Empire. Desperately ill and malnourished, the refugees deluged their German coreligionists with pleas for economic assistance and medical attention. The latter responded by launching numerous ad hoc committees that collected funds throughout Germany and then funneled their receipts to Jewish communities along the frontier; these, in turn, provided relief to the needy. In time, the immediate crisis passed. Many of the Russian Jews remained in Prussia or traveled farther west, some as far as the New World. And the ad hoc committees, convinced that their mission had ended, folded their operations….

“Over the next half-century, the momentum of Jewish emigration from Russia steadily increased. During the 1870s perhaps 40,000 to 50,000 Jews migrated westward. After the pogroms of 1881, however, the trickle turned into a flood as tens of thousands abandoned their homes annually…. By the early twentieth century, over 100,000 such refugees emigrated each year, so that by 1914 at least two and a half million Russian Jews had settled in Western countries, including England, France, Canada, Argentina, and principally the United States.

“Concurrently, Jews from the Austro-Hungarian Empire and Rumania also were on the move. In the face of economic boycotts and rising unemployment at the end of the nineteenth century, Jews emigrated from the Polish sectors of the Hapsburg Empire. Rumanian Jews, too, made their way west after their country denied them citizenship and introduced blatantly anti-Jewish policies….”

(yes, eastern europeans are, on average, more xenophobic than most western european populations. and, judging by the above, they apparently have been for some time).

“…Between 1870 and the outbreak of World War I, over 400,000 Jews left their homes in the Galician, Bohemian, Moravian, Hungarian, and Rumanian lands to seek a new future in Western countries, while and even larger number migrated *within* the Austro-Hungarian Empire.

“Whereas anti-Semitism and impoverization provided the push to drive Jews *from* Eastern Europe, emigrants were also drawn *to* Western lands. They were lured by the promise of eonomic opportunity in the more industrialized West and the knowledge that their fellow Jews in England, France, Germany, and the New World countries enjoyed comparatively greater freedom and prosperity. The promise of toleration and opportunity, therefore, also attracted adventuresome Jews to seek their fortunes in new environments.

funnily enough, during at least some of this period, germany behaved more like macedonia or serbia today, shuffling the migrants onwards to the next country (making a ton of cash in the meantime, sounds like). ‘course the eastern european jews wanted to just migrate through germany, kind-of like the middle eastern/north african/african migrants of today don’t want to stay in macedonia or serbia or hungary [pgs. 13-14]:

“Germany had a vested economic interest in allowing Jewish refugees into the Reich. For Germany — and especially its shipping companies — hoped to benefit from the lucrative business of transporting Eastern Jews to England and America via the ports of Hamburg and Bremen. The sheer number of Jewish transmigrants embarking from German ports was staggering, exceeding 700,000 during the peak years between 1905 and 1914….

“The extent of German interest in encouraging Jewish transmigrant traffic is illustrated by some of the policies pursued by governments and shipping firms. For example, according to Prussian decrees in force between the 1890s and the outbreak of World War I, no Russian transmigrant was officially allowed into Germany without a proper pass, a ticket for passage out of the country, plus an additional sum of money. (Each person over ten years of age had to posses 400 mark, and children needed 100 mark.) Significantly, individuals holding tickets on German ships were exempted from this rule and permitted into the Reich even if they possessed less money. Perhaps the most revealing episode in the campaign to develop the transmigrant traffic occurred in 1893 when the eastern-most states of the Reich sealed their borders in response to cholera epidemics in Eastern Europe. Led by the Hamburg America Line, German shipping companies successfully lobbied for a reversal of this policy, arguing that Jewish transmigrants posed no health risk to the German populace. To further allay fears, shipping firms expended significant sums of money to erect special transport centers in key German cities and vast barrack areas in port cities; such facilities were designed to isolate Jewish travelers from the German populace and thereby eliminate objections to the temporary presence of these Jews on German soil.”

unfortunately, even though most of them didn’t even stay very long in germany, the ostjuden left a bad impression on the minds of germans. i couldn’t even tell you if any of the stereotypes were true or not, and if true by how much — and i really don’t want to get into a discussion about it here and now (although i strongly suspect that eastern european jews are, on average, more clannish than german jews, so there’s possibly that) — but even german jews at the time panicked a bit over the behaviors of their eastern cousins. from Brothers and Strangers: The East European Jew in German and German Jewish Consciousness, 1800-1923 [pgs. 33, 57]:

“German Jews undertook massive charitable work on behalf of the persecuted East European Jews at the same time that they sought the most efficacious means to prevent their mass settlement in Germany….

“Ultimately the difference between German Jews and Ostjuden, both in and out of Germany, was regarded as cultural in nature. Liberal German Jews viewed Eastern Jewish culture as ‘ghetto’ culture which by definition was backward and underdeveloped. The German historical experience had made it abundantly clear that Jewish modernization was conditional upon deghettoization, and this in turn left no room for *Kulturjuden* along the lines still maintained in Eastern Europe.

“This point of view was perfectly understandable. German Jews felt like Germans and their culture *was* German culture. By the beginning of the twentieth century they possessed almost nothing akin to the ‘Jewish’ culture that characterized life in the ghettos of Eastern Europe. The distance they felt, the dissociation from Ostjuden was, then, predicated upon both an objective and subjective reality.”

eastern european jews had a very different (bio-)culture to german jews and gentiles, one that, unfortunately, did not sit well with too many members of the mainstream culture. (the timing was bad, too. more on that below.) am i blaming jews for the holocaust? no. but i am warning — again — that in order to prevent future genocides, we need to understand previous ones, and that includes examining them with a biological/evolutionary eye. as i said previously:

“humans don’t *really* fight and kill neighboring populations or discriminate against subgroups within their nations — not to mention enslave one another — for any of the goofy ideological, religious, or ‘moral’ excuses that they give. those are mostly just after the fact rationalizations that they’ve come up with (no, really — the human brain is not to be trusted!). like other creatures, humans very often try to eliminate or dominate other groups *because they are in competition with them for resources* [pdf] — or, at least, *feel* that they are anyway, whatever the reality on the ground may be.”

bill hamilton pointed to the fourfold increase in the number of ashkenazi jews in eastern europe over the course of just the nineteenth century as a possible contributing factor to the holocaust. this would’ve represent an enormous change in the competition for resources between jews and gentiles in eastern europe. couple that already existing situation to the mass migration of a (bio-)culturally different population into/through germany at the turn of the century, and THEN the appalling economic conditions in germany after wwi and the stock market collapse — further feuling the competition for resources — and you have a recipe for an absolutely horrific biological disaster.

no, i’m not saying that such a scenario is guaranteed to happen again in the west with our new migrants. if there’s enough manna from heaven to go ’round, people probably won’t take it out on their neighbors. (there’s been no genocide of jews in the u.s. where times have generally been pretty good. always.) but i am saying that the powers that be ought to be MUCH more careful in shuffling peoples around willy-nilly. they’re playing a very dangerous game.

Ancient Ethiopian genome reveals extensive Eurasian admixture throughout the African continent“Here, we present a 12.5x coverage ancient genome of an Ethiopian male (‘Mota’) who lived approximately 4,500 years ago. We use this genome to demonstrate that the Eurasian backflow into Africa came from a population closely related to Early Neolithic farmers, who had colonized Europe 4,000 years earlier. The extent of this backflow was much greater than previously reported, reaching all the way to Central, West and Southern Africa, affecting even populations such as Yoruba and Mbuti, previously thought to be relatively unadmixed, who harbor 6-7% Eurasian ancestry.” – h/t john hawks! who tweeted: “First ancient DNA from Ethiopia shows that today’s sub-Saharan Africans are at least 0.2-0.7% Neanderthal ancestry!” – see also: First Ancient African Genome Reveals Vast Eurasian Migration“The man’s genome is, unsurprisingly, more closely related to present-day Ethiopian highlanders known as the Ari than to any other population the team examined, suggesting a clear line of descent for the Ari from ancient human populations living in the area. But further genetic studies show that the Ari also descend from people that lived outside Africa, which chimes with a previous study that discovered a ‘backflow’ of humans into Africa from Eurasia around 3,000 years ago.”

Eight thousand years of natural selection in Europe“The arrival of farming in Europe around 8,500 years ago necessitated adaptation to new environments, pathogens, diets, and social organizations…. We identify genome-wide significant signatures of selection at loci associated with diet, pigmentation and immunity, and two independent episodes of selection on height…. These results suggest that the modern South-North gradient in height across Europe is due to both increased steppe ancestry in northern populations, and selection for decreased height in Early Neolithic migrants to southern Europe. “

The Hybrid Origin of “Modern” Humans“Recent genomic research has shown that hybridization between substantially diverged lineages is the rule, not the exception, in human evolution. However, the importance of hybridization in shaping the genotype and phenotype of Homo sapiens remains debated. Here we argue that current evidence for hybridization in human evolution suggests not only that it was important, but that it was an essential creative force in the emergence of our variable, adaptable species.”

Chorionicity and Heritability Estimates from Twin Studies: The Prenatal Environment of Twins and Their Resemblance Across a Large Number of Traits“There are three types of monozygotic (MZ) twins. MZ twins can either share one chorion and one amnion, each twin can have its own amnion, or MZ twins can—like dizygotic twins—each have their own chorion and amnion. Sharing the same chorion may create a more similar/dissimilar prenatal environment and bias heritability estimates…. We conclude that the influence on the MZ twin correlation of the intra-uterine prenatal environment, as measured by sharing a chorion type, is small and limited to a few phenotypes.”

(note: comments do not require an email. “Humans come then go, that is the way fate decreed on the Tablets of Destiny.”)

jayman’s got a cool new post up on clannishness and western inventiveness! here are a few thoughts from me…

jayman said re. the abstract thinking type of westerners vs. the holistic thinking type of easterners (a la nisbett) [my emphasis]:

“[A]nother key difference between Western vs. Eastern (i.e., WEIRDO vs. clannish) thought: the former see things (and themselves) as atomized individuals, while the latter view objects in the world as part of an interconnected whole. This is a defining aspect on the clannishness dimension: low-clannishness peoples (WEIRDOs) see themselves as atomized individuals, who form associations voluntarily and not necessarily based on kinship. High-clannishness peoples see themselves as inherently part of the group (e.g., family, clan, tribe, village/town, etc.)….

“How did this penchant for abstraction come about among NW Europeans? I suspect that part of it has to do with the rise of high-trust and social atomization (i.e., individualism) in NW European societies. As clannishness disappeared, and as people were no longer bound to their families or clans (and indeed, we were free to interact with non-relative in cooperative ventures), people became more free to engage in intellectually stimulating thought. Mental space previously devoted understand one’s place in society and keep ahead of schemers now could be used on more abstract pursuits.

while it’s an interesting idea, i don’t think that freed up mental capacity once dedicated to clannish traits was co-opted in the brains of westerners (nw europeans) in their post-clannishness state and then devoted greater abstract thought. maybe. but i suspect the connection is (somehow) much more direct: i think (theorize, speculate, etc.) that in simply becoming more independent individuals — i.e. less genetically like others around them thanks to outbreeding — that the mindset simply shifted. atomized individuals, atomized (and, therefore, abstract) thinking. please don’t get your panties all in a bunch. yes, this is complete and wild speculation on my part. i can’t even guess what the mechanism might have been, so don’t sue me if i’m wrong. (nw europeans, btw, began to think of themselves as individuals in the middle of the eleventh century a.d.)

another much more informed guess: that nw europeans’ exceptional ability for inventiveness especially in science (which cannot be divorced from their high average iqs — as jayman pointed out, africans are pretty inventive, but without enough iq points, no one there’s going to the moon) has a LOT to do with the selection pressures that happened thanks to the manor system which was found in nw europe during the middle ages, specifically bipartite manorialism.

to back up for a sec: inventiveness/creativity/scientific reasoning in east asians, or the relative lack of it. jayman suggests that their tendency for holistic — and, therefore, not abstract — thinking hobbles east asians when it comes to inventiveness, etc. that, i think, makes a lot of sense. i do think, though, that the cochran-harpending idea of conformity in east asia (“nails hammered down”/low levels of adhd) also makes a lot of sense. the two ideas go well together, imho. wrt the “nails hammered down” hypothesis, my bet is that that selection process goes waaaay back. complex chinese civilization (that centered around the yellow river valley) is three or four thousands of years old. i think they’ve been hammering down the contrarians/independent thinkers there for a very long time. greg cochran has mentioned that the high-altitude adaptation of tibetans works better than those of other groups adapted to living in the clouds because the tibetan adaptations have been under selection for longer (even some acquired from the denisovans and/or other archaic humans?). i suspect that this is why conformism/lack of independent thinking is so strong in east asia: it’s been under selection there for a very long time. northwest europe’s civilization is obviously much, much younger.

now, to return to northwest “core” europeans: i strongly suspect their inventiveness/abstract thinking style/scientific thinking (and other behavioral traits, for that matter) were selected for thanks to the the following medieval trifecta:

– outbreeding (i.e. the abandonment of close cousin marriage) which meant that the selection for nepostic altruism was curbed since family members would no longer share so many “genes for altruism” in common (see: renaissances), PLUS individuals became “atomized” (therefore more abstract thinking arose, etc.);
– change in family types from extended to nuclear, which again would limit the selection for nepotistic altruism since individuals would interact more with non-kin than family;
bipartite manorialism, which began in frankish territories in northeastern france/belgium and spread across nw and central europe in areas that are pretty much coterminous (prolly not coincidentally) with the hajnal line.

oh. and the ostsiedlung.

bipartite manorialism, in which tenant farmers would work for (later pay rent to) the head of a manor but also farm for themselves, operated as a sort-of franchise system in which the tenants on their individual farms had to make it or break it independently (i.e. without support from an extended family/clan, the dumber members of which would no longer be a drag on our independent farmers). there was, no doubt, cooperation between the tenant farmers which, once the outbreeding reduced the selection for nepotistic altruism, could’ve resulted in the selection for a more general, reciprocal altruism. but bipartite manorialism, i think, would’ve also selected for other traits like a propensity to be hard working, delayed gratification, and inventiveness: those individuals who came up with new ideas for improving their farming (or related) techniques could’ve bettered their place on the manor and been more successful reproductively.

chonologically, bipartite manorialism came first, arising out of the abandoned latifundia system in what had been roman gaul perhaps as early as the 500s. there also appears to have been pressure from very early on on these manors for nuclear families, so the reduction in family size may very well have come next. finally, the avoidance of cousin marriage came into full swing in the frankish territories in the 800s.

the final stage — at least as far as the medieval period goes — in the selection for “core” europeans was the ostsiedling: this was The Big Self-Sorting to the east of individuals who were already well underway to being outbred/manorialized in western germanic regions — in other words, they were well underway to being westernized as we know it. i don’t think it can be a coincidence that the heart of human accomplishment in western europe (which is also pretty much the heart of human accomplishment) is found in the manorialized regions of europe and very much where the ostsiedlung happened (see also here). my bet is that it was very much hard-working, innovative (especially, at the time, in agricultural/engineering techniques), high-achievers who went forth into the east during the medieval period. and they prospered and multiplied once they were there.

so that’s the picture as i see it so far. i reserve the right to change my mind/be utterly and completely wrong. (~_^)

oh. wrt to thinking like a westerner (abstract/atomized) vs. thinking like an easterner (holistic/group), i still suspect that peripheral europeans (like me!) might think more like easterners (i.e. holistically) than northwest “core” europeans. dunno for sure, and i didn’t have enough data to confirm or refute this little idea, but i’m still hanging on to it for now. really wish an actual scientist would check it out.

jayman also said [his emphases]:

“The reality is that evolution proceeds much quicker than you think. Just as HBD’ers generally understand that human evolution didn’t stop 50,000 years ago, it also did not stop 10,000 years ago, or even 1,000 years ago, or even 500 or 200 years ago. Evolution continues right up to the present day. The reason I bring this up is because I keep hearing about how X group was doing this 2,000 years ago or about how Y group was doing this 1,000 years ago, so how could they be so different now? The reason is that they have changed since that time.

hear, hear! and…duh! human evolution is recent, both global and local, ongoing, and can be pretty rapid. not in one generation, obviously, but twenty or forty is plenty of time. also, gene frequencies in populations move upwards or downwards over time — they do not (have to) remain stagnant. i quoted stephen stearns recently (here):

“Well I think what is very probably going on is that selection is moving a population up and down all the time. It goes off in a certain direction for a while, and then it goes back in the other direction. It’s only if you get a significant change in the environment that it will then continuously go in a new direction.”

and average differences in gene frequencies in populations is all you need for average differences in behavioral traits, etc. for example, i think the ancient greeks might’ve moved from a shame to a part-guilt and back to a shame culture again thanks (at least in part) to changes in mating patterns over the course of several hundreds of years. evolution does not have to be unidirectional.

anatoly karlin said:

“Ancient Greeks did a lot of abstract thinking, and produced the greatest cultural/scientific peak until the Renaissance (according to the same Charles Murray’s figures). During the Middle Ages, in pure scientific terms, the Islamic world was most advanced. The Renaissance began in northern Italy. Only in the 17th century did the bulk of scientific discoveries move to NW Europe.”

as i mentioned above, it looks like the ancient greeks (the athenians) went from inbred to outbred and back to inbred again. mind you, i only have some pretty slim historic/literary evidence for that, so you should take my claim with a large grain of salt, but i’ll keep working on the Greek Question. the romans, who were also pretty sharp, at least when it came to engineering, were very clearly outbred (they bequeathed their outbreeding practices to us). the renaissance did begin in northern italy, and that doesn’t come as a big surprise to me ’cause northern italy was the most heavily manorialized part of italy (i’ll tell you more about this in my long overdue series on manorialism). northern italians were also prboably quite outbred during the medieval period, although further research is required on that front, too. the scientific revolution, however — especially the development of the scientific method — was very much a north european baby, though. from what i understand of science in the medieval islamic world, most of that was down to the persians. can’t tell you anything about medieval persian society, unfortunately, ’cause i don’t know anything about it.

that’s it. outta energy. more soon!

What Your DNA Says About Medieval History“A new study uses genetic data from living people to trace millennia-old migration patterns…. [M]uch of what Capelli and his colleagues discovered meshed with what historians already knew. For example, among northern Europeans, highest rate of admixing took place ‘around the late first millennium C.E., a time known to have involved significant upheaval in Europe,’ while admixture between north African and southern European populations was dated to a time span ‘consistent with migrations associated with the Arabic Conquest of the Iberian peninsula.’ But there were surprises, too. Most notably, Capelli and his colleagues discovered evidence for an influx of Mongolians into Europe that predated the reign of Ghengis Khan.” – orig. research article: The Role of Recent Admixture in Forming the Contemporary West Eurasian Genomic Landscape.

Inuit Study Adds Twist to Omega-3 Fatty Acids’ Health Story“A study published on Thursday in the journal Science reported that the ancestors of the Inuit evolved unique genetic adaptations for metabolizing omega-3s and other fatty acids. Those gene variants had drastic effects on Inuit’s bodies, reducing their heights and weights. Rasmus Nielsen, a geneticist at the University of California, Berkeley, and an author of the new study, said that the discovery raised questions about whether omega-3 fats really were protective for everyone, despite decades of health advice. ‘The same diet may have different effects on different people,’ he said…. The researchers found several genetic variants at different locations in the genome that were unusually common in the Inuit, compared with people in Europe or China. Several of these variations occurred within a cluster of genes that direct construction of enzymes called fatty acid desaturases. (The genes are called FADS, for short….) Even more intriguing was the fact that one of these gene variants was present in almost every Inuit in the study. It is much less common in other populations: About a quarter of Chinese people have it, compared with just 2 percent of Europeans. Natural selection is the only known way this gene variant could have become so common in the Inuit. Dr. Nielsen said this adaptation might have arisen as long ago as 20,000 years, when the ancestors of the Inuit were living in the Beringia region, which straddles Alaska and Siberia…. The adaptation did more than just change blood levels of fatty acids, the scientists found. Inuit who carried two copies of the variant gene were on average an inch shorter and 10 pounds lighter than those without a copy.” – orig. research article: Greenlandic Inuit show genetic signatures of diet and climate adaptation. see also Your Genes Are What You Eat from razib.

Height-reducing variants and selection for short stature in Sardinia“[K]nown height-decreasing alleles are at systematically higher frequencies in Sardinians than would be expected by genetic drift.

Are humans still evolving? Yes, both globally and locally. – from jerry coyne.

5 key facts about the nuclear DNA from Sima de los Huesos“If confirmed, the results will push back the H. sapiens-H. neanderthalensis ancestor beyond 400 KYA. Meyer suggested that the ancestors of H. sapiens could have diverged from the branch leading to neandertals and denisovans 550 K to 765 K years ago. It may be possible that H. sapiens evolved in western Eurasia and later migrated back into Africa. The fossils from Europe, Asia and Africa in the 400 Ka. period are physically very diverse and may represent multiple species, only one of which could be the ancestor of today’s humans. For example, Chris Stringer thinks it may be needed to look at Homo antecessor and not Homo heidelbergensis as our last common ancestor with neandertals.”

Origins, admixture and founder lineages in European Roma“We found a set of founder lineages, present in the Roma and virtually absent in the non-Roma, for the maternal (H7, J1b3, J1c1, M18, M35b, M5a1, U3, and X2d) and paternal (I-P259, J-M92, and J-M67) genomes. This lineage classification allows us to identify extensive gene flow from non-Roma to Roma groups, whereas the opposite pattern, although not negligible, is substantially lower (up to 6.3%). Finally, the exact haplotype matching analysis of both uniparental lineages consistently points to a Northwestern origin of the proto-Roma population within the Indian subcontinent.”

This example for male reproduction has been challenged and led to a still unresolved discussion. The scientific debate is shaped by assumptions about reproductive constraints which cannot be tested directly — and the figures used are sometimes arbitrary. Therefore we developed a computer simulation which tests how many copulations per day were necessary to reach the reported reproductive outcome….

there appears to be a north-south divide in spain on several crucial metrics. for example, pisa scores (good proxy for iq scores/intelligence — see here and here):

spain - pisa scores and latitude

gdp per person (2012 — from here):

spain - gdp per person


the speculation in hbd circles has long been that these differences have something to do with southern spain’s moorish history vs. northern spain’s visigothic, later catholic, one. but now, from the upcoming american society of human genetics conference, we have this:


so, if this proves to be correct, the major genetic divide in spain is an east-west one, not a north-south one! as razib pointed out:

why, then, the apparent north-south divide in spain (if it’s real)?

not sure. but there is another major difference between northern and southern spain, and that is in the traditional mating patterns/family types — southern spain is (traditionally) outside the hajnal line, while northern spain falls within it:

hajnal line

in other words, northern spain has for a long time been marked by the western european marriage pattern — i.e. late marriage, fewer children — whereas southern spain has not. from what i can tell, this late marriage pattern is found in those areas of europe in which bipartite manorialism was present during the medieval period, but i honestly don’t know if this holds for spain/the iberian peninsula. i shall endeavor to find out! jayman found, btw, that iq scores in europe correspond pretty well to the hajnal line — higher scores within, lower scores outside the line. this also appears to be the case in spain:

jayman's map + hajnal line

high historic rates of cousin marriage also tend to be present outside the hajnal line. historians generally agree that very close endogamous marriage practices were common in moorish spainfbd marriage even — and they continued right up into (at least) the sixteenth century.

perhaps regional differences in mating patterns/family types persisted in spain despite the movement of peoples during the reconquista. it could be that northerners who moved south through the country, replacing (or eventually outnumbering) the moors, adopted closer mating habits as they moved southwards. it wouldn’t be the first time, i don’t think, that a transplanted group adopted the marriage practices of the broader host population.

dunno. all still speculative at this point. watch this space! (^_^)

Whole genome sequence analyses of Western Central African Pygmy hunter-gatherers reveal a complex demographic history and identify candidate genes under positive natural selection“African Pygmies practicing a mobile hunter-gatherer lifestyle are phenotypically and genetically diverged from other anatomically modern humans, and they likely experienced strong selective pressures due to their unique lifestyle in the Central African rainforest…. Our two best-fit models both suggest ancient divergence between the ancestors of the farmers and Pygmies, 90,000 or 150,000 years ago. We also find that bi-directional asymmetric gene-flow is statistically better supported than a single pulse of unidirectional gene flow from farmers to Pygmies, as previously suggested…. We found that genes and gene sets involved in muscle development, bone synthesis, immunity, reproduction, cell signaling and development, and energy metabolism are likely to be targets of positive natural selection in Western African Pygmies or their recent ancestors.”

Directional dominance on stature and cognition in diverse human populations“[I]ncreased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months’ less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing evidence that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5, 6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been.” – see also Not tonight, cousin from dr. james thompson. and see also Inbreeding from greg cochran. and see also Directional dominance on stature and cognition from steve hsu.

Heritability and the evolution of cognitive traits

CNVs in neuropsychiatric disorders“Over the last few years at least 11 copy number variations (CNVs) have been shown convincingly to increase risk to developing schizophrenia: deletions at 1q21.1, NRXN1, 3q29, 15q11.2, 15q13.3 and 22q11.2, and duplications at 1q21.1, 7q11.23, 15q11.2-q13.1, 16p13.1 and proximal 16p11.2. They are very rare, found cumulatively in 2.4% of patients with schizophrenia and in only 0.5% of controls. They all increase risk for other neurodevelopmental disorders, such as developmental delay and autism spectrum disorders, where they are found at higher rates (3.3%). Their involvement in bipolar affective disorder is much less prominent. All of them affect multiple genes (apart from NRXN1) and cause substantial increases in risk to develop schizophrenia (odds ratios of 2 to over 50). Their penetrance for any neurodevelopmental disorder is high, from ∼10% to nearly 100%. Carriers of these CNVs display cognitive deficits, even when free of neuropsychiatric disorders.”

How evolutionary psychology may explain the difference between male and female serial killers“[R]esearch has shown that male serial killers tend to stalk and kill strangers. But FSKs tend to kill people they know. It seems, then, that MSKs are hunters and FSKs are gatherers.”

Is the Romantic–Sexual Kiss a Near Human Universal – apparently not! – “The romantic–sexual kiss was present in a minority of cultures sampled (46%). Moreover, there is a strong correlation between the frequency of the romantic–sexual kiss and a society’s relative social complexity: the more socially complex the culture, the higher frequency of romantic–sexual kissing.”
