The human migration out of Africa left its mark in mutations“The farther from Africa, the more of them there are.” – h/t billare! – see also: Distance from sub-Saharan Africa predicts mutational load in diverse human genomes.

Genomic Evidence Establishes Anatolia as the Source of the European Neolithic Gene Pool“Kum6 shows a strong population continuity with present-day Sardinia. Kum6 expresses connections to the central Eurasian gene pool. Kum6 shares notable affinity with the Iceman, a 5,300-year-old southern European. Genetic affinities to both East and West suggest continuous contact with Anatolia.”

Ancient Irish had Middle Eastern ancestry, study reveals“Genetic researchers find evidence of mass migration to Ireland thousands of years ago.” – see also: Neolithic and Bronze Age migration to Ireland and establishment of the insular Atlantic genome. and see also from razib: The Gaels Were from Scythia. and from dienekes: Bronze Age people from Ireland had steppe ancestry and R1b. – (my mtDNA hapologroup [more here] — H13a1a — is rather rare in ireland, but is most common in daghestan and may have arisen there. the parent group H originated in the near east.)

The Residents of Vanuatu, Then and Now“Analysis of skulls in the oldest known cemetery in the South Pacific suggests that the earliest inhabitants of Vanuatu may have descended from Asian and Polynesian populations, while modern residents share more physical similarities with people in Melanesia.”

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.”

Discontinuity in the genetic and environmental causes of the intellectual disability spectrum“[O]ur results suggest that most severe ID is a distinct condition, qualitatively different from the preponderance of ID, which, in turn, represents the low extreme of the normal distribution of intelligence.”

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.”

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

Europeans have three times more Neanderthal genes for lipid catabolism than Asians or Africans“Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans. Although Neanderthals are extinct, fragments of their genomes persist in modern humans. These shared regions are unevenly distributed across the genome and some regions are particularly enriched with Neanderthal variants.”

The really old Europe is mostly in Eastern Europe“‘These results confirm Sardinia as a refuge area where ancestry related to Early European Farmers has been best preserved, and also the greater persistence of WHG-related ancestry in present-day Eastern European populations. The latter finding suggests that West European Hunter-Gatherers (so-named because of the prevalence of Loschbour and La Braña) or populations related to them have contributed to the ancestry of present-day Eastern European groups.'” – @eurogenes blog.

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

Language structure: You’re born with it“Humans are unique in their ability to acquire language. But how? A new study shows that we are in fact born with the basic fundamental knowledge of language, thus shedding light on the age-old linguistic ‘nature vs. nurture’ debate.”

Selection for complex traits leaves little or no classic signatures of selection“We present empirical evidence to suggests little discernible ‘selection signature’ for complex traits in the genome of dairy cattle despite very strong and recent artificial selection.” – h/t razib!

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

Facial Width-To-Height Ratio Relates to Alpha Status and Assertive Personality in Capuchin Monkeys“fWHR was positively associated with alpha status and with a dimensional rating of assertive personality in both males and females. Moreover, fWHR showed significant sexual dimorphism in adults but not juveniles, suggesting a developmental change may occur during puberty. In a sub-sample, sex differences were mediated by weight, suggesting fWHR dimorphism does not exceed what would be expected by differences in body weight. This is the first report of an association between face shape and behaviour in a non-human species.” – h/t stuart ritchie!

The relationship between Microcephalin, ASPM and intelligence: A reconsideration“Microcephalin is strongly associated with DNA repair, which indicates a special role for this allele in the intrinsic anti-viral immune response. Enhanced immune functioning may have advantaged both hunter–gatherer and agrarian societies coping with the heightened disease burden that resulted from population growth and exposure to zoonotic diseases, making it more likely that such growth and concomitant increases in intelligence could occur.” – from michael woodley et al. – see also The riddle of Microcephalin – from peter frost.

Caucasian Boys Show Highest Prevalence of Color Blindness Among Preschoolers“The first major study of color blindness in a multi-ethnic group of preschoolers has uncovered that Caucasian male children have the highest prevalence among four major ethnicities, with 1 in 20 testing color blind. Researchers also found that color blindness, or color vision deficiency, in boys is lowest in African-Americans, and confirmed that girls have a much lower prevalence of color blindness than boys.”

Genetic Influences Are Virtually Absent for Trust“Here we examine a population-based sample of 1,012 twins and relatives. We show that the genetic influence on generalized trust in other people (trust-in-others: h2 = 5%, ns), and beliefs regarding other people’s trust in the self (trust-in-self: h2 = 13%, ns), is virtually absent…. We show that, relative to cognitive abilities, psychiatric disorders, and classic personality variables, genetic influences are smaller for trust, and propose that experiences with or observations of the behavior of other people shape trust more strongly than other traits.” – h/t rene bekkers!

Psychopaths: how can you spot one?“But is psychopathy a disorder – or a different way of being…? If someone’s brain lacks the moral niceties the rest of us take for granted, they obviously can’t do anything about that, any more than a colour-blind person can start seeing colour. So where does this leave the concept of moral responsibility? ‘The legal system traditionally asserts that all people standing in front of the judge’s bench are equal. That’s demonstrably false,’ says the neuroscientist David Eagleman, author of Incognito: The Secret Lives of the Brain. He suggests that instead of thinking in terms of blameworthiness, the law should deal with the likelihood that someone will reoffend, and issue sentences accordingly, with rehabilitation for those likely to benefit and long sentences for those likely to be long-term dangers.” – h/t (heh!

Equal ≠ The Same: Sex Differences in the Human Brain“At the root of the resistance to sex-influences research, especially regarding the human brain, is a deeply ingrained, implicit, false assumption that if men and women are equal, then men and women must be the same. This is false. The truth is that of course men and women are equal (all human beings are equal), but this does not mean that they are, on average, the same. 2 + 3 = 10 – 5, but these expressions are not the same. And, in fact, if two groups really are different on average in some respect, but they are being treated the same, then they are not being treated equally on average.”

Why We Fight (Over Land)“In the most recent issue of the journal International Security, Monica Duffy-Toft and Dominic Johnson, political scientists at Oxford, argue that a new theoretical framework is needed to analyze such behavior, one rooted in evolutionary biology…. As Duffy-Toft told me an interview today, ‘It comes back to survival and reproduction. There’s an instinct that we need land in order to exist. We need to have the capacity to get resources to live our lives….’ Duffy-Toft acknowledges that the thesis is controversial. While their piece is currently the lead article in International Security, one of the more prestigious journals in the field, it took almost 10 years to get it published. ‘We’re pushing up against real biases in our field,’ she says. ‘Scholars don’t want to admit that our behavior can be constrained by the fact that we’re animals.’ – *sigh* – original research article here [pdf].

The Son Becomes The Father“The failure of parents to appreciably affect the outcomes of their children affirms Gregory Clark’s findings, and indicates that much of the transmission of status from one generation to the next is ultimately genetic in origin…. Almost certainly, throughout history, and across the diverse societies, that has been a huge amount of ‘noise’ in the transmission of status, especially on the individual level and in the short run. The vagaries of the circumstances no doubt imbued good fortune on some and dashed the success of many others. But through it all, the thing that is at the root of continuity – DNA – remained the active ingredient to propagate lineages in their respective places through out the ages.” – from jayman.

The lower IQs of blacks in this sample cannot therefore be put down to them having been exposed to environments less conducive to the expression of genetic variance in IQ than the environments experienced by whites.” – @human varieties.

Humans have been known to attribute awareness to plants, rocks, rivers, empty space, and the universe as a whole.

The Oldest Living Things On Earth“Starting in the 1960s, evolutionary biologists have searched for an overarching explanation to account for all the different ways to grow old. The best-supported ones so far are variants on the old truth that a jack-of-all-trades is a master of none. An organism can collect a finite amount of energy, whether it’s a lion killing gazelles, a tulip capturing sunlight, or a microbe breathing iron at the bottom of the sea. It can use that energy to grow, to produce offspring, to defend itself against pathogens, to repair damaged its damaged molecules. But it has a limited budget. The energy spent on one task is energy that can’t be spent on others. Molecular repair and pathogen defense are both good ways to live longer. But a long-lived organism that produces few offspring will not pass on many copies of its genes to future generations. The organisms that will succeed are the ones that do a mediocre job of keeping their bodies in order, leaving more energy for making babies.” – h/t billare!

Mutation, Not Natural Selection, Drives Evolution – according to masatoshi nei: “Every part of our body is controlled by molecules, so you have to explain on a molecular level. That is the real mechanism of evolution, how molecules change. They change through mutation. Mutation means a change in DNA through, for example, substitution or insertion [of nucleotides]. First you have to have change, and then natural selection may operate or may not operate. I say mutation is the most important, driving force of evolution. Natural selection occurs sometimes, of course, because some types of variations are better than others, but mutation created the different types. Natural selection is secondary.”

End the Hype over Epigenetics & Lamarckian Evolution“They insist that characteristics many researchers assume to be the result of epigenetic inheritance are actually caused by something else. The authors list four possibilities: Undetected mutations in the letters of the DNA sequence, behavioral changes (which themselves can trigger epigenetic tags), alterations in the microbiome, or transmission of metabolites from one generation to the next. The authors claim that most epigenetic research, particularly when it involves human health, fails to eliminate these possibilities.” – h/t jayman!

New warning about ‘Celtic Curse’ blood iron disease“Hemochromatosis is a hereditary disease, linked particularly to Irish and those of Irish origin. It causes your body to absorb too much iron from the food you consume. The excess iron becomes stored in your organs, especially your liver, heart and pancreas. It can lead to life-threatening conditions such as cancer, heart problems and liver disease. Those with Irish heritage have a significantly greater chance of carrying the gene mutation that can contribute to the deadly disorder. Some experts believe that hemochromatosis originated more than 40,000 years ago in Ireland when genes mutated allowing the population to over-absorb iron, to compensate for a poor iron diet.” – h/t 23andMe!

The state is the worst wicked stepmother of all“[T]he number of children raised without one of their parents has increased sharply in recent years, partly due to changing sexual mores but also the involvement of the state itself; the largest increase in non-marital births came after the 1977 Homeless Persons Act gave lone mothers priority on housing lists. The Tory MP behind this proposal wrote, ‘The sad truth is that, until now, the Wicked Stepmother would have got away scot-free.’ Possibly, but there would not have been so many wicked stepmothers, or stepfathers, or mother’s current boyfriends, without the state in the first place.” – from ed west.

Pseudoescepticismo y biodiversidad humana“Desde hace años, sin embargo, existe una tendencia ideológica inflacionaria en el movimiento escéptico que tiende a alejarse del ‘núcleo’ original, cuyos contornos de todos modos son imprecisos (¿es la parapsicología una ciencia?). El inconveniente es que este alejamiento del núcleo, yo lo llamaría ‘escepticismo inflacionario’ o simplemente pseudoescepticismo, desdibuja los criterios de demarcación y hace que los nuevos temas sean más y más propensos a la contaminación moral e ideológica…. Un caso bastante claro es la campaña ‘escéptica’ de descrédito contra la psicología evolucionista, que sólo ha convencido a un pequeño grupo. ¿Pudiera ser que el empeño de grupos ‘escépticos’ de asimilar el movimiento de biodiversidad humana con el ‘racismo científico’ y con la ‘pseudociencia’ (la falacia moralista siempre merodeando) corriera una suerte parecida?” – @la revolución naturalista.

The other explanation offered states that expecting mothers would have been under considerable stress as the population dwindled. This prenatal stress could have had negative consequences for fetal development.” – h/t avi tuschman!

uncle bob beat me to this (hey uncle bob! *waves* (^_^) ). i’ve been meaning to post about human accomplishment in core europe ever since agnostic posted about it last month on his blog.

here, from charles murray’s Human Accomplishment, is a map of “concentrations [of accomplishment] within the european core”:

charles murray - human accomplishment map - european core

from murray (via agnostic):

“The colored regions in the European core (light and dark blue together) account for the origins…of fully 50 percent of the total European significant figures. Just the five regions colored dark blue — Ile de France, Southeast England, Tuscany, Belgium, and the Netherlands — account for 26 percent of the European total. The other 24 percent come from (in order of their contribution) Bavaria, Venetia, Southwest England, Switzerland, Lowland Scotland, Lower Saxony, Saxony, Baden-Wurttemberg, Northeast Austria, the Italian Papal States, and Brandenburg….

“Or you can think of it another way: 80 percent of all the European significant figures can be enclosed in an area that does not include Russia, Sweden, Norway, Finland, Spain, Portugal, the Balkans, Poland, Hungary, East and West Prussia, Ireland, Wales, most of Scotland, the lower quarter of Italy, and about a third of France.”

*ahem*

the dark blue area of belgium, the netherlands, ile de france, and southeast england is definitely the core area of europe that — thanks to the early enthusiasm of the franks for christianity and the church’s cousin marriage bans AND the franks’ invention of manorialism — has been outbreeding for the longest amount of time out of all the europeans. (see “mating patterns in europe series” below ↓ in left-hand column for more details.) belgium + the netherlands + ile de france = austrasia, which is where manorialism got started. the franks brought the manor system, and the cousin marriage bans, with them on their trek across/conquest of the east — the light blue bits in germany. there is also evidence for the manor system early on in kent and the south of england, not to mention some very early secular laws against cousin marriage in those parts of england. the manor system was introduced in lowland scotland — along with many actual lords of those manors from normandy — by king david. (no, not that onethis one.)

these areas — along with parts of northern italy (the flat parts) — are what i’ve been calling my “core europe” — the most outbred of the europeans (who are, in turn, the most outbred of almost anybody on the planet). although northern italy — tuscany — i’m not 100% sure about. i have found a little evidence suggesting that medieval northern italians maybe avoided marrying their cousins — and perhaps the genetics backs that up — but Further Research is RequiredTM.

as uncle bob said: “Where there was the most outbreeding there was the most accomplishment. Look specifically at northern Italy, England, and central Europe. I find this astonishing.”

me, too!

J.P. Rushton’s theory of ethnic nepotism [pdf] – “Ethnic nepotism due to similarity is a weak social force compared to social identity. However its pervasiveness makes it a potential driver of evolutionary and social change, a potential borne out by sociological studies of the impact of ethnic diversity on social cohesion and public altruism. Genomics confirms the theory for interactions within populations with sufficient genetic diversity, such as ethnically mixed societies. GST [genetic similarity theory] applied to ethnicity is promising for further research in evolutionary social science because it unifies evolutionary and behavioral mechanisms in a single theory.” – from salter and harpending. h/t hbd bibliography!
