Grisly find suggests humans inhabited Arctic 45,000 years ago“When they dated the remains [of the mammoth], the researchers got another surprise: The mammoth died 45,000 years ago. That means that humans lived in the Arctic more than 10,000 years earlier than scientists believed, according to a new study. The find suggests that even at this early stage, humans were traversing the most frigid parts of the globe and had the adaptive ability to migrate almost everywhere.”

Genetic affinities of the Jewish populations of India“Consistent with the previous observations, we detected minor Middle Eastern specific ancestry component among Indian Jewish communities, but virtually negligible in their local neighbouring Indian populations. The temporal test of admixture suggested that the first admixture of migrant Jewish populations from Middle East to South India (Cochin) occurred during fifth century. Overall, we concluded that the Jewish migration and admixture in India left a record in their genomes, which can link them to the ‘Jewish Diaspora’.”

The Welfare Trait – dr. james thompson on adam perkins‘ book. make sure not to miss the series of follow-up posts!

A Review of Adam Perkins’s ‘The Welfare Trait’“Painstakingly, Perkins constructs his core argument: that the welfare state, the foundational institution of modern Britain (the Church of England having sadly declined), contains the seeds of its own eventual destruction. A large body of evidence, which Perkins reviews, supports the intuitive idea that habitual welfare claimants tend to be less conscientious and agreeable than the average person. Such habitual claimants also tend to reproduce at higher rates than the general population, a pattern found across nations and time periods. They also seem to adjust their fertility in response to changes in the generosity of welfare provision, having fewer children in times of austerity and more when governments turn on the spigot marked ‘spending’. Over time, therefore, the work motivation of the general population is lowered. This occurs through both genetic and environmental channels. Personality traits are substantially heritable (meaning that a decent percentage of the variation in these traits is due to naturally occurring genetic variation). Given this fact, habitual welfare claimants with employment-resistant personalities are likely to have offspring with similar personalities.” – from andrew sabisky.

The evolution of the age at menarche from pre-historical to modern times“Data from skeletal remains suggest that in the Paleolithic female menarche occurred at an age between 7 and 13 years, early sexual maturation being a trade-off for reduced life expectancy. In the classical, as well as in the medieval years, the age at menarche was generally reported to be at about 14 years, with a range from 12-15 years. A significant retardation of the age at menarche occurred in the beginning of the modern times, soon after the industrial revolution, due to the deterioration of the living conditions, most studies reporting menarche to occur at 15-16 years. In the 20th century, especially in the second half of it, in the industrialized countries, the age at menarche decreased significantly, as a result of the improvement of the socioeconomic conditions, occurring between 12-13 years. In the present times, in the developed countries, this trend seems to slow down or level-off.” – h/t neuroskeptic!

Why parenting may not matter and why most social science research is probably wrong and How to Find a Parenting Effect – from brian boutwell! – from the first article: “Whether it’s a study purporting to link some aspect of parenting to child development, or a study intended to link some new diet fad to weight loss, the results are unclear if they did not control for genetics. Lest someone put words into my mouth later, this does *not* mean that every correlation reported by social scientists is the result of correlated genetic influences. The point, however, is that we have spent decades churning out correlations and we have no idea whether the findings were polluted by unmeasured genetic factors. That’s frightening, especially since public policies have been built on some of these potentially illusory correlations. The standard way of doing business in the social sciences ignores genetic influences, and has for years. Be careful which findings you cling to. Most social science research can only reveal associations; which is important, no doubt, but I presume you want to know something about causality also (i.e., if you eat bacon everyday what’s the chance that it’ll *cause* you to get cancer; that sort of thing). To even begin approximating causality (assuming you cannot do an experiment, which you can’t with most social science research), you must account for all confounding factors—genes included.”

Status Decreases Dominance in the West but Increases Dominance in the East“Across two experiments, having high status decreased punishment by American participants but increased punishment by Chinese and Indian participants. Moreover, within each culture, the effect of status on punishment was mediated by feelings of being respected. A final experiment found differential effects of status on punishment imposed by Asian Americans depending on whether their Asian or American identity was activated.” – h/t timothy bates!

Assortative Mating for Educational Level in Parents of Public School Children (N > 7000 Individuals) in the Lagos State, Nigeria“Approximately 61.5 % of the parents had spouses at the same level of education. More mothers than fathers married upward in educational level. The assortative mating coefficients for educational level were .52–.61 across respondents’ classes, .51–.62 across six school districts, and .57 (.55–.59) in the total sample. Overall, these results were very similar to the findings from Western or Asian samples, providing evidence to support the robustness of human mating pattern in educational attainment across different cultures and ethnic groups.”

‘The Bell Curve’ 20 years later: A Q&A with Charles Murray“The lesson, subsequently administered to James Watson of DNA fame, is that if you say it is likely that there is *any* genetic component to the black-white difference in test scores, the roof crashes in on you. On this score, the roof is about to crash in on those who insist on a purely environmental explanation of all sorts of ethnic differences, not just intelligence. Since the decoding of the genome, it has been securely established that race is not a social construct, evolution continued long after humans left Africa along different paths in different parts of the world, and recent evolution involves cognitive as well as physiological functioning.”

Why Some of the Worst Attacks on Social Science Have Come From Liberals“In the halls of social-science academia, where liberals [have a numerical advantage], it’s telling that some of the same sorts of feeding frenzies occur. This should stand as a wake-up call, as a rebuke to the smugness that sometimes infects progressive beliefs about who ‘respects’ science more. After all, what both the Bailey and Chagnon cases have in common — alongside some of the others in Galileo’s Middle Finger — is the extent to which groups of progressive self-appointed defenders of social justice banded together to launch full-throated assaults on legitimate science, and the extent to which these attacks were abetted by left-leaning academic institutions and activists too scared to stand up to the attackers, often out of a fear of being lumped in with those being attacked, or of being accused of wobbly allyship.”

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Bits of Mystery DNA, Far From ‘Junk,’ Play Crucial Role“As scientists delved into the ‘junk’ — parts of the DNA that are not actual genes containing instructions for proteins — they discovered a complex system that controls genes. At least 80 percent of this DNA is active and needed. The result of the work is an annotated road map of much of this DNA, noting what it is doing and how. It includes the system of switches that, acting like dimmer switches for lights, control which genes are used in a cell and when they are used, and determine, for instance, whether a cell becomes a liver cell or a neuron.”

…than violent republicans, that is. at least according to one study.

the set-up from boing boing:

“Nathan Kalmoe, a Ph.D. candidate in political science at the University of Michigan … ran an online survey, involving a diverse group of 412 adults from all across the United States. The survey respondents read two political ads—one that used neutral words like ‘work for’, and the other that used metaphorically violent works, like ‘fight’. Then they responded to statements about what was and wasn’t acceptable behavior. Things like, ‘Some of the problems citizens have with government could be fixed with a few well-aimed bullets.'”

and the results from josh rosenau’s blog:

“‘[E]ven mild violent language increases support for political violence among citizens with aggressive predispositions, especially among young adults.’

“This effect is not uniform. Most people reject any attempt to justify political violence, and for most people, seeing a violent political ad doesn’t change that. But Sides explains:

‘Seeing violence political ads DID have an effect among those with a predisposition to aggression, as measured with a standard psychological battery. Among those with the greatest predisposition to aggression, being exposed to a violent political ad increased their support for political violence by about 20 points on a 100-point scale. Among those with the least predisposition to aggression, being exposed to a violent ad actually decreased their support for violence.

‘This conditional relationship — between seeing violent ad and a predisposition to aggression — appears stronger among those under the age of 40 (vs. those older), men (vs. women), and Democrats (vs. Republicans).'”

so, watch what you say to young, aggressive, male LEFTISTS.

half sigma wrote the other day:

“As much as I wish that there weren’t as many Jewish liberals, unfortunately it’s not uncommon to find prominent liberals who are Jewish. Anti-Semites, however, exaggerate the Jewishness of the left. The majority of leftists are gentile. Nancy Pelosi is a gentile. Barrack Obama is a gentile. Al Gore is a gentile. The Norwegian Noble Committee members, who awarded the Peace Prize to Al Gore and Barrack Obama, are gentile.”

his comment reminded me of the oj trial.

at some point in the oj trial, the prosecution pointed out that oj had beaten his wife during their marriage. the defense responded with some brilliant statistical tomfoolery: most wife beaters don’t kill their wives. i don’t remember what the prosecution responded to that — if anything it was prolly something stoooopid. but what they shoulda responded was, “no, most wife beaters don’t kill their wives, but most wife killers beat their wives.”

similarly, the interesting thing about jews in the west is not that they make up the majority of the left (as half sigma points out, they don’t), but that the majority of jews are leftists (see here and here).

that’s not what makes some people anti-semitic, tho. no, it’s much simpler than that. anti-semitism is caused by the same, biological factors as any other sort of “anti-” feeling that one group of people has towards another (and u have to admit, the world is NOT lacking in such feelings).

groups of people be hatin’ on other groups of people because they are unrelated or not-related-enough to each other, genetically speaking.

/full and complete explanation

and western jews — ashkenazi jews — are not-related-enough to any of the european peoples amongst whom they live. ergo, conflict.

that’s all there is to it. really. (well, things can ride along pretty well in places where groups are mixed provided there’s plenty of resources to go ’round, but if there’s some sort of resource|economic crisis, watch out.)

but, if u add on top of the not-related-enough-ness the differing political sentiments on average of jews (see above), plus other things like jews feeling more like “world citizens” than other european|american populations (i.e. not feeling so tied to whatever country they happen to be living in) … well, then … houston, we have a problem.

the sooner we all get it through our thick skulls that human behavior is rooted in biology, just like the behavior of all other living creatures on this god-forsaken rock, the sooner we’ll be able to deal realistically with the discordancies between us all. (and by “deal realistically” i mean in a peaceful, civilized way, in case u were wondering. i know things can be taken up wrongly on the interwebs!)
