John Derbyshire On Nicholas Wade’s A TROUBLESOME INHERITANCE – A Small, But Significant, Step For Race Realism“Wade raises high the banner of race realism and charges head-on into the massed ranks of the SSSM. He states his major premise up front, on page two: ‘New analyses of the human genome have established that human evolution has been recent, copious, and regional.’ Those last four words are repeated at intervals throughout the narrative. They are, as it were, the keynote of the book; Wade returns to them many times to anchor his observations — and some speculations — on the history and development of human societies.” (my emphasis there – h.chick)

henry harpending on science“[T]his is perhaps at the heart of the slander of the so called hbd-crew that circulates. Most of us are really interested, in our hearts, in theory and models. This is the way that most of science works…. You state somewhere that the hbd crew is obsessed with IQ. Seems so, but wait! IQ is literally the only thing that can be reliably measured of a whole constellation of interesting traits. It really does work in the sense of telling one whom to hire or whom to admit to graduate school. You also speak of what we ‘believe’ but the whole fun of science is falsifying hypotheses, not believing them. I would give my eye teeth (if I had them) to come up with something besides IQ to look at.” (my emphasis again – h.chick)

Digging For Gold: Study Says Your Race Determines Your Earwax Scent – h/t hbd bibliography!

Austronesians Out of the Cauldron“…the emergence of Austronesians. Linguistics and archaeology already were rather clear on the pattern of expansion, and when. But now an ancient DNA remain from off the coast of Fujian dated to ~8,000 years ago solidifies in totality the where and when. This is not an argument anymore.” – from razib.

New Diet, Sexual Attraction May Have Spurred Europeans’ Lighter Skin“[A] new study of ancient DNA concludes that European skin color has continued to change over the past 5000 years, suggesting that additional factors, including diet and sexual attraction, may also be at play.” – see also: Natural selection has altered the appearance of Europeans over the past 5,000 years.

Pause Is Seen in a Continent’s Peopling“Using a new method for exploring ancient relationships among languages, linguists have found evidence further illuminating the peopling of North America about 14,000 years ago. Their findings follow a recent proposal that the ancestors of Native Americans were marooned for some 15,000 years on a now sunken plain before they reached North America.”

One Million Brits ‘Descended from Vikings” DNA Study Claims“Around one million Britons, or one in 33 men across the UK, can claim direct descent from Vikings, according to a new DNA study. Men from the far north of Scotland were most likely to provide a direct match with almost a third (29.2%) of the men from the Shetland Islands testing positive for Viking blood.” – h/t ed west!

Genetic Architectures“The point is that the genetic architecture of a quantitative trait does not have to be the same in different populations of the same species. For example, I have the impression that height is not as highly polygenic in Pygmies as it is most other human populations. There’s a particular region on chromosome 3 that seems to influence height- you don’t see such a concentration in Europeans.” – another from greg cochran.

Molecular genetic contributions to socioeconomic status and intelligence – h/t billaire! who tweeted: “21% of the var. in education level, 18% of SES, 29% of cognitive ability explained by COMMON SNPs in Scottish sample.”

Study finds genetic link between height and IQ“A team of researchers at Edinburgh University in Scotland has found a correlation between genes associated with height and those associated with intelligence. In their paper published in the journal Behavior Genetics, the group describes how they studied the DNA of 6,815 unrelated people and discovered what they describe as a direct correlation between height and intelligence—taller people are smarter, they say.”

Intelligent people are more likely to trust others“Intelligent people are more likely to trust others, while those who score lower on measures of intelligence are less likely to do so, says a new study. Researchers based their finding on an analysis of the General Social Survey, a nationally representative public opinion survey carried out in the United States every one to two years.” – h/t mr. mangan, esq!

Want Success? Choose the Right Parents“Gregory Clark’s startling new book, ‘The Son Also Rises,’ asks you to rethink everything you thought you knew about social mobility. His research, if it’s correct, isn’t good news. It says that socio-economic status is mostly a matter of nature not nurture, and suggests that trying to help the disadvantaged move up won’t make much difference.” – h/t alice teller! – see also: Social mobility: Have and have not“Mr Clark follows his logic to an unexpectedly egalitarian end. Redistribution is sensible, he argues, not in order to boost mobility but because mobility is intractably low. The cream will rise regardless, and so paying extraordinary salaries to capable workers is unnecessary. If high rates of mobility are used to excuse or justify inequality, he suggests, then the reality of low mobility implies something quite different: t hat great inequality serves little purpose and redistributing income from the rich to the poor might raise overall welfare at little economic cost. This makes for uncomfortable reading for those of all ideological persuasions.”

Why HBD“As I have tired to explain in my earlier post, Environmental Hereditarianism, the behavioral and physical traits of people are environmentally context-dependent. The broad environmental context regulates the expression of the genes. There is *not* a dichotomy between genes and ‘environment’. Nor could there be one – we are always ‘with’ both. The broad environment includes geography, climate, technology, and prevailing social landscape (otherwise known as ‘culture’). When the social-technological-geographic landscape changes, you can have broad behavioral change all without genetic change. This explains secular changes that occur too quickly to be a result of evolution, such as the sexual revolution, the modern rise in irreligiosity, the increase in the obesity rate, etc.” – from jayman.

Key connection“Biologists zero in on role of plasticity in evolution. For more than a century, scientists have suggested that the best way to settle the debate about how phenotypic plasticity — the way an organism changes in response to environment — may be connected to evolution would be to identify a single mechanism that controls both. Harvard researchers say they have discovered just such a mechanism in insulin signaling in fruit flies. Cassandra Extavour, an associate professor of organismic and evolutionary biology, and grad student Delbert André Green II were able to show that a single molecular pathway plays a role in both heritable changes in the flies’ number of ovarioles — egg-producing compartments in the ovaries — and in how they react to their environments by shutting down some ovarioles. The study is described in a paper published this month in the Proceedings of the Royal Society B. ‘This is the first example, to my knowledge, that shows this link — between heritability and plasticity — being controlled by the same mechanism,’ Extavour said. ‘What we’ve done with this paper is show that an important trait that controls how many offspring a fruit fly will have exhibits both heritable variation and phenotypic plasticity, and that both are controlled by insulin signaling.’” – h/t steven pinker!

Morality and the Lament of the Liberal Atheists“Moral relativism is the ground state of living things. It doesn’t work for a social species like ours. If every one of us tried to monopolize all the available resources within his grasp at the cost of everyone else, the chances that any given individual would survive and reproduce would be drastically reduced. Therefore, morality. It exists because, from an evolutionary perspective, it works. It will continue to function just as it always has, even if 100,000 philosophers shout at the top of their lungs that it’s irrational. Of course it is, but it doesn’t matter. We will continue to perceive the good and evil that seem so real to our imaginations as absolutes. It is our nature to do so….” – from helian

Hypothesis on Why Northwest Europe Began Outbreeding“It could just be coincidence that the outbreeding areas that coincide with other positive hajnal line traits were also lands conquered by men from tribes with the traditions of Germanic kingship. These kings were illiterate barbarians seeking legitimacy and thinking long term at the security of their line ruling…. This is a hypothesis, but the position these rulers were in was one of new conquerors in foreign lands. They needed to create and encourage loyalty in the natives as well as find a way to secure their individual line as king in a manner that was different from what their people, the conquerors, were accustomed to. The Church, an institution eager for power in a new area as well, offered an opportunity to import a political infrastructure and change the social make up of their new lands. Even moreso in England than the rest of core Europe, the Church and the elite’s motivations and goals overlapped perfectly. Christianity was new to them and new to the Britains, but as conversions mounted, it was a shared trait amongst them all. That shared identity was the warrior-chiefs’ way to have rule and kingship legitimized. That shared identity made the natives and newcomers men of Kent or East Anglia, later England, and not of the clan.” – good stuff from son of brock landers!

Do Women’s Mate Preferences Change Across the Ovulatory Cycle? A Meta-Analytic Review – answer: yes. – see also: Intersexual conflict across women’s ovulatory cycle“Results indicate that (a) men are particularly self-assertive toward partners when their partners are fertile; (b) similarly, women are especially self-assertive toward partners when they are fertile; (c) women report engaging in more behaviors that resist male vigilance and mate-guarding when they are fertile, especially in ways that are unobservable to male partners; (d) these effects are especially strong when women themselves report greater attraction to men other than partners when they are fertile, compared to the luteal phase.” – h/t robert burriss!

Study finds less cooperation among women than among men where hierarchy is involved“‘When I studied young children, I noticed that boys were typically interacting in groups, and girls tended to focus on one-on-one relationships,’ said Benenson, the study’s lead author, who explored similar questions in her book Warriors and Worriers. ‘There is even evidence that these differences exist in six-month-olds – but you can see it with the naked eye by about five or six years old, where boys form these large, loose groups, and girls tend to pair off into more intense, close friendships.’ What makes those differences particularly provocative, Benenson said, is that chimpanzees organize their relationships in nearly identical ways. ‘Chimpanzee males usually have another individual they’re very close with, and they may constantly battle for dominance, but they also have a larger, loose group of allies,’ Benenson said. ‘When it comes to defeating other groups, everybody bands together. I would argue that females don’t have that biological inclination, and they don’t have the practice.’”

Personality Traits and Body Mass Index in a Korean Population“Compared with the normal weight groups, overweight and obese men scored higher on openness to experience and lower on conscientiousness. Overweight and obese women scored lower on neuroticism and openness to experience and higher on agreeableness. Extraversion was positively associated with BMI in men (β = 0.032, P<0.05). BMI and waist circumference were significantly increased in individuals who were less dutiful. In women, neuroticism was inversely associated with BMI (β = −0.026, P<0.05). Openness to experience was negatively, and agreeableness was positively, associated with BMI (openness to experience: β = −0.072, agreeableness β = 0.068) and waist circumference (openness to experience: β = −0.202, agreeableness: β = 0.227) (P<0.05).”

The Costume of Shangri-La: Thoughts on White Privilege, Cultural Appropriation, and Anti-Asian Racism – it’s worth quoting the whole abstract: “This piece poses cultural appropriation as an undertheorized aspect of white privilege in White Privilege Studies. By way of narrative exploration, it asserts that a paucity of scholarship on Orientalism and anti-Asian racism has created a gap in White Privilege Studies that curbs its radical transformative potential. It argues for the value of a structural and historically focused lens for understanding the issue of cultural appropriation, and extends questions of culture and race relations beyond the borders of the United States. It also explores the complex ways that interracial and transnational relationships can influence white racial identity, and illustrates the disruptive potential that queer interracial relationships can offer to dominant historical patterns of white behavior.” – (~_^) h/t ben southwood!

Y-chromosome “Adam” was not necessarily human“From the point of view of population genetics, there is absolutely no reason that the common ancestor of all human Y chromosomes must have existed in an individual that we would identify as ‘human’.”

Genomic variation in sharing between siblings“Visscher et al make really nice use of this slight variability in how much of the genome sibs share to learn about how much variation in height within a population is due to genetic variation. They use the fact that sibs who share slightly more of their genome (>0.5) should have more similar heights, than sibs who share less of their genomes (<0.5). This allows them to partition out how much of the resemblance between siblings is due to a shared environment, as opposed to shared genomes…. It also makes me wonder if sibs are actually unconsciously, weakly aware of these subtle genomic differences (through their similarity in a range of traits, including height etc). I could imagine doing a study where siblings (or others) are asked to assess how similar they are/feel, and then assessing whether this is weakly correlated with the fraction of the genome shared. I keep meaning to followup on this idea with some popgen theory to assess how this might play out in modifying kin-selection and altruism between sibs and other relatives." – from graham coop [this guy].

The Dark Enlightenment Hits Stage Two

La ciencia estúpida“La mayoría de los grandes científicos y filósofos no eran lo que diríamos tipos agradables. Tampoco eran políticamente correctos según el canon normal. Prácticamente ningún filósofo o científico anterior a la escuela de Frankfurt podría dar hoy una clase pública sin la amenaza de ser molestado por una turba emancipatoria. Hume, Darwin, Voltaire, Locke, Kant (no digamos ya Platón o Aristóteles) hoy no podrían ser contratados en la universidad de un país occidental.” – from eduardo zugasti.

Why the masculine face? Genetic evidence reveals drawbacks of hyper-masculine features“[A]round half the variation in both male and female facial masculinity could be attributed to additive genetic variation…. The extensive genetic variation in masculinity makes more plausible the idea that choosing to mate with a masculine man can result in more attractive offspring. But the genes that made a male face more masculine did not make it more attractive. Worse, these same genes made female faces more masculine and thus less attractive. Families that make manly-looking sons tend also to make masculine-looking daughters.”

Casting Out The Devil“[C]onservatives generally think that liberals are misguided, and live in deep denial of obvious truths about human nature and the way the world actually works (as opposed to the way they think it *ought* to work), liberals view conservatives not just as misguided, but as *morally evil*.” – from malcolm pollack.

Capturing a Hard-Wired Variability: What Makes Some Identical Twins Noticeably Different?“The current study finds that only one allele is expressed in between 12 and 24 percent of all such pairs encoded by the mouse genome. Further, the selection of expressed alleles varies randomly from cell to cell, and switches frequently between the two options throughout their lives…. ‘We find that for those genes that are not imprinted, roughly one in five alleles is randomly and dynamically expressed only one at a time,’ says Sandberg. ‘And if one allele is being expressed, the other doesn’t know about it. There’s no coordination between two.’”

A Living Time Capsule Shows the Human Mark on Evolution“Scientists have revived shrimp-like animals that have been buried at the bottom of the lake for an estimated 700 years. If this estimate holds up to further testing, they are the oldest animals ever resurrected…. The oldest DNA the scientists obtained from the lake dates back to around the time the Vandals were ransacking Rome. The scientists found that one genetic strain of water fleas dominated at the time — and continued to until the late 1800s. As phosphorus [from fertilizers] flooded the lake, a previously rare strain emerged and took over.”

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.”

One language is written on top of the other, which is why the second language remained hidden for so long.”duons. – see also Exonic Transcription Factor Binding Directs Codon Choice and Affects Protein Evolution.

Environment drives genetic changes in Evolution Canyon“[R]esearchers with the Virginia Bioinformatics Institute at Virginia Tech studying fruit flies that live on opposite slopes of a unique natural environment known as ‘Evolution Canyon’ show that even with migration, cross-breeding, and sometimes the obliteration of the populations, the driving force in the gene pool is largely the environment.” – see also Genome differentiation of Drosophila melanogaster from a microclimate contrast in Evolution Canyon, Israel.

Big brains are all in the genes“Scientists have moved a step closer to understanding genetic changes that permitted humans and other mammals to develop such big brains…. Dr Humberto Gutierrez, from the School of Life Sciences, University of Lincoln, UK, led research which examined the genomes of 39 species of mammals with the aim of better understanding how brains became larger and more complex in mammals…. The researchers found a clear link between increased brain size and the expansion of gene families related to certain biological functions.”

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.”

H. Heidelbergensis Preferred Island Life“[B]etween 500,000 and 200,000 years ago, Homo heidelbergensis preferred to live on islands in the flood plains of major rivers, where they would have had access to big herbivores that grazed on the rich grasses, water birds and plants with edible roots, and leafy vegetables. The island itself offered protection from other hungry predators, and raw materials such as wood and stone for fashioning tools would have been abundant.”

Older Dads: Possible Links to Autism, Schizophrenia in Offspring – inherited epigenetic effects? – “Maria Milekic, PhD, reported today, at the American College of Neuropsychopharmacology annual meeting in Hollywood, Florida, that old mice have an epigenetic change ‒ a loss of DNA methylation at the locations where the genetic code starts being transcribed. 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.

Human brain hard-wired for rural tranquillity“Humans may be hard-wired to feel at peace in the countryside and confused in cities – even if they were born and raised in an urban area…. Dr Ian Frampton, an Exeter University psychologist, stressed the researchers still had more work to do, but said they may have hit upon something significant…. Professor Michael Depledge of Exeter University, a former Environment Agency chief scientist, said urban dwellers could be suffering in the same way as animals kept in captivity. He said the move to the cities had been accompanied by an ‘incredible rise in depression and behavioural abnormalities’.” – h/t ed west!

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.”

‘Rare’ Gene Common in African Descendants, May Contribute to Heart Disease“Researchers at Weill Cornell Medical College have found that a genetic variation that is linked to increased levels of triglycerides — fats in the blood associated with disorders such as heart disease, type 2 diabetes, obesity and stroke — is far more common than previously believed and disproportionally affects people of African ancestry…. The finding offers a clue as to why Africans and people of African descent have an increased risk of cardiovascular disease and type 2 diabetes compared to many other populations, says the study’s senior author, Dr. Ronald Crystal, chairman of genetic medicine at Weill Cornell. African Americans with the variant had, on average, 52 percent higher triglyceride levels compared with blacks in the study who did not have the variant…. The gene variant the scientists studied is a single point mutation — a replacement of one of DNA segment with another — in the ApoE gene, which carries fats and other molecules through the blood.” – h/t hbd bibliography!

Predicting Human Body Height from DNA“Predicting tall stature from these 180 DNA variants resulted in an accuracy of 0.75 on a scale from 0.5 (meaning random prediction) to 1.0 (completely accurate prediction). ‘Although the achieved DNA-based prediction accuracy for tall stature is still somewhat lower than we previously established for eye color, hair color and age,’ said Kayser, ‘I expect that upcoming new knowledge on height genetics will further increase the accuracy in predicting tall stature, and eventually the full range of body height, from DNA.’”

Study Connects Dots Between Genes, Human Behavior“The team studied individuals with a rare disorder known as Williams syndrome.

Butterflies show origin of species as an evolutionary process, not a single event“The evolution of new species might not be as hard as it seems, even when diverging populations remain in contact and continue to produce offspring…. ‘We find that only a small fraction of the genome is markedly different between closely related species, but then much more of the genome — more than you’d expect — shows similar differences between more distantly related species…. That indicates that the genetic changes that are important for causing speciation are tightly clustered early in speciation, but not so later on in the process; the overall pattern of genome divergence starts slow and then skyrockets.’”

Mating advantage for rare males in wild guppy populations“Negative frequency-dependent selection (NFDS), a form of selection in which genotypes are favoured when they are rare, can potentially maintain such extensive polymorphism, but few experimental studies have confirmed its operation in nature…. Here we use highly replicated experimental manipulations of natural populations to show that males with rare colour patterns have higher reproductive fitness, demonstrating NFDS mediated by sexual selection. Rare males acquired more mates and sired more offspring compared to common males and, as previously reported, had higher rates of survival.” – h/t rob brooks!

Japanese north–south gradient in IQ predicts differences in stature, skin color, income, and homicide rate“In Japan, there is IQ gradient from north to south. Stature and average income cline is also from north to south. Homicide rates increase from north to south. Fertility rates and suicide rates decrease from north to south. Infant mortality is not correlated with latitude.”

Global patterns of sex-biased migrations in humans“We found that genetic differentiation between populations was higher for Y chromosome than for the mtDNA at global scales. The migration rate of female might be three times higher than that of male, assuming the effective population size is the same for male and female.” – h/t hbd bibliography!

Shape Differences Between the Faces of Homosexual and Heterosexual Men“Homosexual men showed relatively wider and shorter faces, smaller and shorter noses, and rather massive and more rounded jaws, resulting in a mosaic of both feminine and masculine features.” – h/t neuroskeptic!

The rule-dependence model explains the commonalities between the Flynn effect and IQ gains via retesting“[W]e propose that Flynn effect gains are partly a function of the degree to which a test is dependent on rules or heuristics. This means that testees can become better at solving ‘rule-dependent’ problems over time in response to changing environments, which lead to the improvement of lower-order cognitive processes (such as implicit learning and aspects of working memory). These in turn lead to apparent IQ gains that are partially independent of general intelligence. We argue that the Flynn effect is directly analogous to IQ gains via retesting, noting that Raven’s Progressive Matrices is particularly sensitive to both the effects of retesting and the Flynn effect.” – from woodley and armstrong! (^_^) – see also dr. thompson.

Civilizations rise and fall on the quality of their soil“Great civilisations have fallen because they failed to prevent the degradation of the soils on which they were founded…. This is according to Professor Mary Scholes and Dr Bob Scholes who have published a paper in the journal Science, which describes how the productivity of many lands has been dramatically reduced as a result of soil erosion, accumulation of salinity, and nutrient depletion.”

Bad reporting generates bad arguments“The Sunday Times gets 3.5 million readers a week. Anything mentioned in it has a chance of influencing public understanding and opinion in Britain. Last week they did a piece on Professor Robert Plomin’s recent book ‘G is for Genes’ which focuses on the genetic contribution to scholastic achievement. The newspaper’s coverage was misleading….” – of course. – from dr. james thompson.

Embryo Selection for Cognitive Enhancement“We find that embryo selection, on its own, may have significant impacts, but likely not drastic ones, over the next 50 years, though large effects could accumulate over multiple generations. However, there is a complementary technology, stem cell-derived gametes, which has been making rapid progress and which could amplify the impact of embryo selection, enabling very large changes if successfully applied to humans.” – h/t mike anissimov!

They might be giants – from greg cochran.

Why Can’t We All Just Get Along? The Uncertain Biological Basis of Morality“[S]ome of our deepest moral intuitions are gut feelings that are with us for no more lofty a reason than that they helped our ancestors protect themselves and spread their genes.” – h/t urho lintinen! – see also: You Can’t Learn About Morality from Brain Scans.

War Before Civilization – from peter turchin.

Cooperation and conflict between women in the family“Reproductive competition within and between families may have underpinned the biological evolution of fertility patterns (such as menopause) and the cultural evolution of marriage, residence, and inheritance norms (such as late male marriage or primogeniture), which can enhance cooperation and minimize the observed incidence of such conflicts.”

Do human females use indirect aggression as intrasexual competition strategy? [pdf] – yes. (duh.) – h/t michael w. story!

Bone flute discovery indicates 9000 years of Chinese music tradition“Archaeologists announced the discovery of three ancient flutes made of red-crowned crane bones that may prove that Chinese have been playing music for 9,000 years. The flutes were excavated at an ancient tomb in the site of a Neolithic settlement in Henan Province…. The bone flutes, pictured above, are thought to be the world’s earliest heptatonic musical instruments ever discovered.”

Total Fertility Rate“Oversimplifying, if your tribe has 60 men and 40 women, if each woman has two kids during her lifetime, when the next generation turns over, your population will have declined from 100 people to 80. Conversely, if your tribe has 40 men and 60 women, and each woman has two kids, your tribe will have grown from 100 to 120. The female sex is the limiting factor when it comes to reproduction, after all.” – from the awesome epigone.

Earlier Onset of Puberty in Girls Linked to Obesity“[T]he respective ages at the onset of breast development varied by race, body mass index (obesity), and geographic location. Breast development began in white, non-Hispanic girls, at a median age of 9.7 years, earlier than previously reported. Black girls continue to experience breast development earlier than white girls, at a median age of 8.8 years. The median age for Hispanic girls in the study was 9.3 years, and 9.7 years for Asian girls. Body mass index was a stronger predictor of earlier puberty than race or ethnicity.” – h/t hbd bibliography!

What color are Whites?“In reality, most *Français de souche* act as individuals and have only a weak sense of their collective interest. Collective action is instead wielded by better organized factions, particularly the globalized business community—which lobbies hard to outsource employment to low-wage countries and insource low-wage workers.” – from peter frost.

bonus bonus: There’s a global morality gap — and it’s getting wider“It is now clear, though not much talked about, that humanity, all 7.1 billion of us, tends to fall into one of two distinct camps. On the one side are those who buy into the whole post-Enlightenment human rights revolution. For them the moral trajectory of the last 300 years is clear: once we were brutal savages; in a few decades, the whole planet will basically be Denmark, ruled by the shades of Mandela and Shami Chakrabarti. And there’s some truth in this trajectory — except for the fact that it only applies to half the planet. The other half resolutely follows a different moral code: might is right, all men were not created equal and there is a right and a wrong form of sexual orientation. You can identify those countries in the dark half of the divide by their attitudes to homosexuality and women; to honour killings, race, disability, mental illness, religious minorities and to crime, torture and punishment, even animal rights and the environment.” – h/t ed west!

Is Beauty in the Face of the Beholder?“We concluded that individuals, if given the opportunity, seek to promote ‘positive assortment’ for Self’s phenotype, especially when the level of similarity approaches an optimal point that is similar to Self without causing a conscious acknowledgment of the similarity.” – on assortative mating, via race/history/evolution notes.

3.4-7.9% Neandertal admixture in Eurasia?“‘Our analysis allows us — for the first time — to formally reject a history of ancestral population structure and instead reveals strong support for admixture from Neandertals into Eurasian populations at a higher rate (3.4%-7.9%) than suggested previously.’” – @dienekes’.

and speaking of neanderthals: Neanderthals made leather-working tools like those in use today.

Genetics and alcoholism“Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person’s risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2.”

Jason Richwine and some Hispanic data“In summary, if one uses scholastic data as a measure of ability, then there was some significant narrowing of the White/Hispanic gap in the early 1980’s, but that reduced gap has persisted thereafter. This finding discomforts those who predicted that the gap would never change, and those who said it was closing fast and would shortly disappear. Both are wrong, are partially right.” – from dr. james thompson.

Population Structure of Hispanics in the United States: The Multi-Ethnic Study of Atherosclerosis“By comparing genetic ancestry of MESA Hispanic participants to reference samples representing worldwide diversity, we show major differences in ancestry of MESA Hispanics reflecting their Caucasian, African, and Native American origins, with finer differences corresponding to North-South geographic origins that separate MESA Mexican versus Central/South American samples. Based on our analysis, we define four subgroups of the MESA Hispanic cohort that show close agreement with the following self-identified regions of origin: Dominican/Cuban, Mexican, Central/South American, and Puerto Rican.” – via nelson.
