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!

Is DNA Multilingual?“The genetic code has traditionally been viewed as a universal set of instructions, exquisitely tuned to maintain robust stability and allow evolution-sustaining mutations. But the pervasive occurrence of recoded stop codons, and the backchannel crosstalk between microbes and viruses, paints a more intricate picture of multilingual genetic instructions.”

Jelly genome mystery“The uniqueness of this ctenophore’s nervous system leads Moroz and his team to argue that it must have evolved independently, after the ctenophore lineage branched off from other animals some 500 million years ago.”

Genomic divergence in a ring species complex“Ring species provide particularly clear demonstrations of how one species can gradually evolve into two, but are rare in nature…. Here we use genome-wide analyses to show that, although spatial patterns of genetic variation are currently mostly as expected of a ring species, historical breaks in gene flow have existed at more than one location around the ring, and the two Siberian forms have occasionally interbred.” – h/t razib!

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’.

this one’s for linton!: Why Marrying Your Cousin May Pay Off“In line with previous findings, the researchers found that among non-foraging societies, a couple’s relatedness was linked with having more surviving children. But among foraging societies, the opposite was true: More-closely related spouses had fewer surviving children. Furthermore, the more family intermarriage in a society, the greater the benefit of intermarrying on the number of children couples had. In other words, in societies in which people frequently married their relatives, intermarrying showed a stronger link to having more children.”

Genetic and educational assortative mating among US adults“We find that spouses are more genetically similar than two individuals chosen at random but this similarity is at most one-third the magnitude of educational similarity.”

Irish fair skin can be traced to India and the Middle East“A major new US study at Penn State University has found that Europeans’ light skin stems from a gene mutation from a single person who lived 10,000 years ago…. Keith Cheng from Penn State College of Medicine reported that one amino acid difference in the gene SLC24A5 is a key contributor to the skin color difference between Europeans and West Africans…. ‘The mutation in SLC24A5 changes just one building block in the protein, and contributes about a third of the visually striking differences in skin tone between peoples of African and European ancestry, he said…. 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. All individuals from the Middle East, North Africa, East Africa and South India who carry the A111T mutation share traces of the ancestral genetic code. According to the researchers, this indicates that all existing instances of this mutation originate from the same person.” – h/t 23andMe!

The puzzle of European hair, eye, and skin color“The physical appearance of Europeans seems to result from a selection pressure that acted primarily on women and only secondarily on men. This is especially true for highly visible traits on or near the face—the focus of visual attention.” – from peter frost.

Heritability of brain volume change and its relation to intelligence“Human brain volumes change throughout life, are highly heritable, and have been associated with general cognitive functioning…. Results show that changes in volumes of total brain (mean=-6.4ml; -0.5% loss), cerebellum (1.4ml, 1.0% increase), cerebral white matter (4.4ml, 0.9% increase), lateral ventricles (0.6ml; 4.8% increase) and in surface area (-19.7cm2, -1.1% contraction) are heritable (h2=43%; 52%; 29%; 31%; and 33%, respectively). An association between IQ (available for 91 participants) and brain volume change was observed, which was attributed to genes involved in both the variation in change in brain volume and in intelligence. Thus, dynamic changes in brain structure are heritable and may have cognitive significance in adulthood.”

Does brain structure determine your political views?“‘People like to believe that their own political beliefs are rational, that they’re a sensible response to the world around them, so when we come along and say, “Maybe there are these predispositions, influential but perhaps not fully in your conscious awareness,” that’s not the way we like to view our own political beliefs.'” – h/t mr. robert ford!

Sex-Related Neuroanatomical Basis of Emotion Regulation Ability“Behavioral research has demonstrated that males have a higher capability of regulating their own and others’ emotions than females; however, little is known about the sex-specific brain mechanisms involved in emotion regulation ability…. we found the sex differences in the neuroanatomical basis of emotion regulation ability. Males showed a stronger positive relation between emotion regulation ability and regional gray matter volume (rGMV) in the right dorsolateral prefrontal cortex. In contrast, females demonstrated a stronger positive relation between emotion regulation ability and rGMV in an anatomical cluster that extends from the left brainstem to the left hippocampus, the left amygdala and the insular cortex.”

Privilege and Morality“Our species isn’t good at nuance. The ‘privilege’ debate will and must take place in a morally charged context. It is not possible to sanitize the discussion by scrubbing it free of moral emotions. That is one of the many reasons why it is so important to understand what morality is and why it exists. It does not exist as a transcendental entity that happened to pop into existence with the big bang, nor does it exist because the Big Man upstairs wants it that way. It exists because it evolved.” – from helian.

Economic Growth & Human Biodiversity“Economic growth in lower-IQ countries does not invalidate either the reality of IQ differences between countries or the persistence of those disparities.” – from pseudoerasmus.

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!

DNA USA*“[A]bout about 4 percent of whites have at least 1 percent or more African ancestry. Although it is a relatively small percentage, the percentage indicates that an individual with at least 1 percent African ancestry had an African ancestor within the last six generations, or in the last 200 years. This data also suggests that individuals with mixed parentage at some point were absorbed into the white population. Looking a little more deeply into the data, Kasia also found that the percentage of whites with hidden African ancestry differed significantly from state-to-state. Southern states with the highest African American populations, tended to have the highest percentages of hidden African ancestry…. Previous published studies estimate that on average African Americans had about 82 percent African ancestry and about 18 percent European ancestry. But in self-identified African Americans in 23andMe’s database, Kasia found the average amount of African ancestry was closer to 73 percent. Kasia found significant differences in state-to-state comparisons. African Americans in the northern and western states have more mixed ancestry than those in the southern states…. On average Latinos had about 70 percent European ancestry, 14 percent Native American ancestry and 6 percent African ancestry. The remaining ancestry is difficult to assign because the DNA is either shared by a number of different populations around the world, or because it’s from understudied populations, such as Native Americans.” – from 23andMe.

Common Variants in the CDH7 Gene are Associated with Major Depressive Disorder in the Han Chinese Population“Recent genome-wide association study also demonstrated that CDH7 was significant associated with bipolar disorder….

Humans May Have Been Stuck on Bering Strait for 10,000 Years“In the new Perspectives article, published today (Feb. 27) in the journal Science, the researchers compile existing data to support the idea, known as the Beringia standstill hypothesis. Among that evidence is genetic data showing that founding populations of Native Americans diverged from their Asian ancestors more than 25,000 years ago. In addition, land in the region of the Bering Strait teemed with grasses to support big game (for food) and woody shrubs to burn in the cold climate, supporting a hard-scrabble existence for ancient people.” – razib is skeptical.

Was skin cancer a selective force for black pigmentation in early hominin evolution?“[D]ata on age-associated cancer incidence and lethality in albinos living at low latitudes in both Africa and Central America support the contention that skin cancer could have provided a potent selective force for the emergence of black skin in early hominins.”

Neanderthal Introgression at Chromosome 3p21.31 Was Under Positive Natural Selection in East Asians“Studies of the Neanderthal and Denisovan genomes demonstrate archaic hominin introgression in Eurasians. Here, we present evidence of Neanderthal introgression within the chromosome 3p21.31 region, occurring with a high frequency in East Asians (ranging from 49.4% to 66.5%) and at a low frequency in Europeans. We also detected a signal of strong positive selection in this region only in East Asians…. [S]uggestive evidence supports latitude-dependent selection, implicating a role of ultraviolet-B.”

Neanderthals challenge the origins of speech“Neanderthals, may well have spoken in languages not dissimilar to the ones we use today…. [I]n terms of mechanical behaviour, the Neanderthal hyoid was basically indistinguishable from our own, strongly suggesting that this key part of the vocal tract was used in the same way. ‘From this research, we can conclude that it’s likely that the origins of speech and language are far, far older than once thought.'” – h/t billare (who is 0.1% neanderthal)!

The man who destroyed America’s ego“How a rebel psychologist challenged one of the 20th century’s biggest—and most dangerous—ideas…. Among the most egregious errors they discovered were those in the papers that focused on academic performance. A correlation had been repeatedly found between high self-esteem and good grades. So, the logic went, if you boosted self-esteem you’d also boost grades. But the authors had made one of the most elementary mistakes in science. ‘When they tracked people over time,’ says Baumeister, ‘the grades came first, and then the self-esteem. High self-esteem was a *result* of good grades, not a cause.'” – h/t matthew wygant!

Genetic Influences on Political Ideologies: Twin Analyses of 19 Measures of Political Ideologies from Five Democracies and Genome-Wide Findings from Three Populations“Here we present results from original analyses of a combined sample of over 12,000 twins pairs, ascertained from nine different studies conducted in five democracies, sampled over the course of four decades. We provide evidence that genetic factors play a role in the formation of political ideology, regardless of how ideology is measured, the era, or the population sampled…. We then present results from one of the first genome-wide association studies on political ideology using data from three samples: a 1990 Australian sample involving 6,894 individuals from 3,516 families; a 2008 Australian sample of 1,160 related individuals from 635 families and a 2010 Swedish sample involving 3,334 individuals from 2,607 families. No polymorphisms reached genome-wide significance in the meta-analysis. The combined evidence suggests that political ideology constitutes a fundamental aspect of one’s genetically informed psychological disposition, but as Fisher proposed long ago, genetic influences on complex traits will be composed of thousands of markers of very small effects and it will require extremely large samples to have enough power in order to identify specific polymorphisms related to complex social traits.”

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. Despite recent popularity of studying episodic memory in animals, such phenomenological consciousness has been extremely difficult to demonstrate…. 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.”

DNA methylation is a biochemical process that plays an important regulatory role in development and disease. The work was done by a research team in the Department of Psychiatry at Columbia University. Offspring of old fathers showed the same deficit in DNA methylation, and they differed in their behavior from the offspring of the young fathers.”

Genetics accounts for more than half of variation in exam results @the guardian – “[T]he authors point out that genetics emerges as such a strong influence on exam scores because the schooling system aims to give all children the same education. The more school and other factors are made equal, the more genetic differences come to the fore in children’s performance. The same situation would happen if everyone had a healthy diet: differences in bodyweight would be more down to genetic variation, instead of being dominated by lifestyle.” – see also Nature more than nurture determines exam success @newscientist – “Overall, across the three core subjects of English, mathematics and science, achievement was 58 per cent determined by genetics. Individually, achievement was 52 per cent down to genetics for English, 55 per cent for maths and 58 per cent for science. The figure for humanities was lower at 42 per cent. This was a surprise to Plomin because, traditionally, excellence in humanities subjects such as art or music is considered to be ‘handed down’ from parents, whereas science is considered a product of the teaching environment.” – see also The genetics route could spell a new direction for education @the independent – “[I]t may be that the innate differences in children’s abilities because of their genes could argue the case for a more tailor-made individual curriculum to offset the disadvantages of birth.” – no sh*t! – see also New twin study by Plomin, Shakeshaft et al from steve sailer – see also Strong Genetic Influence on a UK Nationwide Test of Educational Achievement at the End of Compulsory Education at Age 16.

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.”

Promiscuity Is Pragmatic“Why women and other female primates seek out multiple partners…. [T]here are two environmental contexts where women commonly choose multiple partners.

It may also explain why female infidelity has increased in Western societies as women have gained greater political and economic independence…. The second environmental context Scelza identified is where the sex ratio is female-biased (indicating a scarcity of men) or there is a high level of male unemployment (indicating a scarcity of men who can provide support).” – one for the gameboyz.

Our IQs Are Climbing, But We’re Not Getting Smarter – re. woodley and armstrong paper.

Academic experts criticise Boris Johnson IQ claims“Dr James Thompson, senior lecturer in psychology at University College London, said Boris had been ‘inelegant’ in his choice of words. Thompson, co-author of Cognitive Capitalism, said: ‘What Boris Johnson has done is inelegantly describe things which in fact do seem to be true: intelligence, however you assess it, is predictive. It’s predicative of income, life span and of occupational status. People are different and have different futures and intelligence seems to be an important part of that.’ He said studies showed there seemed to be a correlation between ‘being bright in youth and doing well in life later’. Asked if inequality was inevitable, he said: ‘In one way that is true. There’s two things, one is that some people are brighter than others and can do more complicated work and that more complicated work is generally more valued.’ However, he added that how much people should be paid was a decision for society. Professor Richard Lynn, co-author of IQ and the Wealth of Nations, said that the association between IQ and income was ‘only modest’. ‘That is because some high IQ people go into jobs that don’t have particularly high earnings like university professors, schoolteachers or social workers. Some professions attract very high IQ people but they don’t have very high earnings,’ he said. ‘You could say that the IQ is only one determinant of high earnings, the others are ambition and motivation and the third one is luck.'” – h/t holtz!

Migration Hurts the Homeland“The migration that research shows is unambiguously beneficial is the kind in which young people travel to democracies like America for higher education and then go home.

Their skills raise the productivity of the unskilled majority, and their attitudes accelerate democratization…. Many on the left, for their part, don’t like to recognize that we’re taking away fairy godmothers. They prefer to believe that they’re helping poor people flee difficult situations at home. But we might be feeding a vicious circle, in which home gets worse precisely because the fairy godmothers leave.

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.”)

anyway…

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…

(note: comments do not require an email. the party which i self-identify with the most.)

just started reading avi tuschman‘s Our Political Nature: The Evolutionary Origins of What Divides Us. so far it’s very good! mind you, i’ve only read the first two chapters (there are twenty-three altogether). (~_^)

according to tuschman, his goal in writing this book is [from the preface - my emphasis]:

“[T]o paint a compelling and accurate portrait of our nature as political animals. Today’s political commentators would have us believe that we vote based on our views about the main issues of the day, on our economic circumstances, or on our longtime affiliations with this political party or that. That’s wrong, or at least incomplete. Step by step, I will explain that our political orientations are not simply intellectual constructs, flowing from our upbringing, our schooling, our peer groups, or which newspapers we read. No, our political orientations are actually natural dispositions, molded within each of us by powerful evolutionary forces.

excellent!

in the first two chapters, tuschman reviews some of the major research out there which has found that personality is largely innate and that personality strongly influences our political orientations (left-wing or right): the blocks’ study showing that personality at age four strongly correlates with political orientation as an adult (in one’s 20s) [pdf], for example, and alford et al.’s twin studies which showed that identical twins reared apart have very much the same political orientations [pdf], and so on.

well, he doesn’t need to persuade me! (~_^) left and right — we are “born this way.”

furthermore, tuschman says we’ll find these innate left/right personalities in all societies. he draws, though, what i think is a slightly awkward comparison between all of the rebellious folks in the arab spring and the occupy wall street movement in the western world [chapter 1]:

“[I]t was precisely Basboosa’s [the tunisian man who immolated himself triggering the so-called arab spring] moral *rejection of inequality* that activated one of these universal hot buttons residing within him, and within so many of his compatriots. And this is why his story resonated with a critical mass of people in the Middle East, for whom Basboosa symbolized the humble, well-meaning common man systematically abused by government fiat and corruption.

“Now, the story of Basboosa might seem rather remote to many American readers. But the same hidden trigger at play in the Middle East underlies the concurrent transformation of the political landscape in the United States. As the Arab Spring was unfolding, the ‘Occupy Wall Street’ movement emerged on the far left of the US spectrum. The demonstrators in New York shouting, ‘We are the 99 percent!’ were railing not against Middle Eastern dictators, but rather against bankers and large corporations. And yet the same issue that ignited the Arab Spring had inspired and galvanized their movement: a moral rejection of economic and social *inequality*.”

well, yeah … sort of … maybe. but i’m not certain that there are equally as many individuals in tunisia — or north africa — concerned about equality for everybody as there are in the united states or western europe. there might be a lot of people p*ssed off in the arab world/middle east/north africa that they, personally, experience so much corruption in their daily lives and that they and their families are often cheated by others, but are they really morally rejecting economic and social inequality to the same degree that, say, a swede does? i dunno, but it’s worth asking.

just looking quickly at one set of responses from the world values survey [1981-2002 waves] to the question…

“How would you place your views on this scale? – Incomes should be made more equal vs We need larger income differences as incentives.”

…we find that north africans are very much for GREATER income inequality [click on chart for LARGER view]:

wvs - income equality

i think it would be very safe to bet that different populations will vary not only in the numbers/proportions of leftists vs. rightists found within them but also in how liberal or conservative their left- or right-wingers are.

but i think i’m getting ahead of tuschman and that he’s actually going to get to this later in the book. for instance, in chapter two, he does say:

“What happened when groups of very different genetic backgrounds live in the same environment? In this case, each group’s average personality scores differed according to the *origin of their ancestors*. For example, the personality traits of white South Africans clustered closer to the Swiss, while black South Africans had personalities more similar to Zimbabweans. Likewise, groups that have traditionally lived in geographically adjacent territories have more similar average personalities than groups separated by large distances.”

so i should prolly finish reading the book before i say any more on this. (^_^)

Ancient DNA Links Native Americans With Europe“…from the complete nuclear genome of a Siberian boy who died 24,000 years ago — the oldest complete genome of a modern human sequenced to date. His DNA shows close ties to those of today’s Native Americans. Yet he apparently descended not from East Asians, but from people who had lived in Europe or western Asia. The finding suggests that about a third of the ancestry of today’s Native Americans can be traced to ‘western Eurasia,’ with the other two-thirds coming from eastern Asia…. It also implies that traces of European ancestry previously detected in modern Native Americans do not come solely from mixing with European colonists, as most scientists had assumed, but have much deeper roots.” — see also: The First of the Mohicans from greg cochran.

Your face may have been sculpted by junk DNA“There is a huge degree of variation in human faces but, as family resemblances show, the overall shape is heavily constrained by genetics. However, so far, geneticists have identified only a small number of genes that influence the shape. These explain just a tiny fraction of the variation seen in human faces. According to Axel Visel of the Lawrence Berkeley National Laboratory in California and his colleagues, more variation is controlled by distant-acting enhancers. These are short sequences of DNA, in non-coding regions of the genome, that can influence the activity of the facial genes, even if they are a long way along the DNA strand.”

Behavior problems in preschool and child care centers may be an issue of genes“A new study suggests that some children may be genetically predisposed to developing behavioral problems in child care and preschool settings…. [B]irth parents who had high rates of negative emotion and self-control, based on a self-reported temperament scale, were more likely to have children who struggled with behavioral issues such as lack of self-control and anger, in child care centers. They controlled for adoptive parent’s characteristics, and still found a modest effect based on the genetic link.”

Your Ethnicity Determines the Species of Bacteria That Live in Your Mouth“[P]eople from each of the four different ethnic groups represented in the study (all participants self-identified as either Caucasian, African-American, Chinese or Latino) generally had similar species of bacteria, especially underneath the gums. As a result, simply by counting which varieties of bacteria appeared in this area, the researchers developed a model that was able to guess a person’s ethnicity with an accuracy significantly better than chance — it got it right 62 percent of the time. Some groups were even easier to identify via the bacteria than others: It could correctly identify Latinos 67 percent of the time and African-Americans with 100 accuracy. The variation along ethnic lines, they believe, is a reflection of genetics, not environment. That’s because, if you assumed that the mouth microbiome is totally dependent on environmental factors, you’d expect that members of the same ethnic group would have different mixes of bacteria depending on whether they were first-generation immigrants to the U.S. or had family histories that stretched back generations in the country. Instead, people’s background — in terms of foods they ate and other lifestyle trends — didn’t seem to have any correlation with the bacterial communities in their mouths. – h/t super bob!

Herpes virus genome traces the ancient path of human migration“Researchers…sequenced the genomes of 31 samples of herpes simplex virus type-1 to reconstruct how it hitchhiked on humans as they dispersed around the world. The results match the pattern proposed by the ‘Out of Africa’ theory, which has become the most widely accepted scenario for ancient human migration. The analysis showed that African strains of the virus contained the most genetic diversity — suggesting that they had the oldest roots.”

Genetic variation alters efficacy of antidepressant“Having a different form of a gene that regulates the brain chemical noradrenaline influences how well men remember negative memories after taking the antidepressant drug reboxetine, according to a study published in the October 23 issue of The Journal of Neuroscience. The findings demonstrate how genes can influence antidepressant response.” – see also: Genes predispose some people to focus on the negative.

Low historical rates of cuckoldry in a Western European human population traced by Y-chromosome and genealogical data“[W]e estimate that over the last few centuries, EPP rates in Flanders (Belgium) were only around 1–2% per generation. This figure is substantially lower than the 8–30% per generation reported in some behavioural studies on historical EPP rates, but comparable with the rates reported by other genetic studies of contemporary Western European populations. These results suggest that human EPP rates have not changed substantially during the last 400 years in Flanders and imply that legal genealogies rarely differ from the biological ones.” – h/t rob brooks!

Asymmetries in altruistic behavior during violent intergroup conflict“Some empirical studies on intergroup conflict in hunter-gatherer societies and chimpanzees indicate that fitness relevant risks and potential benefits of attacks and defenses might have differed substantially under ancestral conditions. Drawing on these studies, it is hypothesized that the success of defenses was much more important for individual and kin survival and that a disposition to act altruistically during intergroup conflict is thus more likely to evolve for the strategic situation of defense…. Analyzing detailed historical case data from 20th century wars, this study finds that altruistic behavior towards members of the in-group indeed seems to occur more frequently when soldiers are defending themselves and their comrades against enemy attacks.” – h/t hbd bibliography!
