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.

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.

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.

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

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

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

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

New Paltz Neandertal Project

We are a research team from the Psychology Department of SUNY New Paltz conducting a research study examining the relationship between genotype and behavior. We are recruiting participants who are at least 18 years old, fluent in English, and who have had their DNA sequenced by a genomics company to complete a short survey (approx. 45 minutes).

the idea is to find out if any particular personality/behavioral traits correlate with neanderthal alleles.

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.

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.

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.

Other animals don’t wonder why one thing is good and another evil. They’re not intelligent enough to worry about it. Hominids are Mother Nature’s first experiment with creatures that are smart enough to worry about it.

Speculations on the Evolution of Awareness“The ‘attention schema’ theory provides one possible account of the biological basis of consciousness, tracing the evolution of awareness through steps from the advent of selective signal enhancement about half a billion years ago to the top-down control of attention, to an internal model of attention (which allows a brain, for the first time, to attribute to itself that it has a mind that is aware of something), to the ability to attribute awareness to other beings, and from there to the human attribution of a rich spirit world surrounding us. Humans have been known to attribute awareness to plants, rocks, rivers, empty space, and the universe as a whole. Deities, ghosts, souls-the spirit world swirling around us is arguably the exuberant attribution of awareness.” – h/t neuroskeptic!

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.

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.

Immediate replacement of fishing with dairying by the earliest farmers of the northeast Atlantic archipelagos [i.e. british isles] – “These new findings…unequivocally confirm rejection of marine resources by early farmers coinciding with the adoption of intensive dairy farming. This pattern of Neolithization contrasts markedly to that occurring contemporaneously in the Baltic, suggesting that geographically distinct ecological and cultural influences dictated the evolution of subsistence practices at this critical phase of European prehistory.”

The booms and busts of Neolithic Europe (and their potential impact on our DNA)“most of the interactions between the genetically Near Eastern-like Neolithic farmers and indigenous European hunter-gatherers, including mixing, in all likelihood took place on the peripheries of the farming societies. If so, then perhaps every time there was a bust, it was the relatively more admixed, or even more hunter-gatherer-like, farmer groups from the peripheries that took advantage of the situation and moved in to grab some land in the depopulated regions? In other words, this might have been the process which led to the well-documented reemergence of hunter-gatherer-derived ancestry in the heart of Europe after the early Neolithic.” – @eurogenes.

The findings suggest that life on Earth today may not have come about by ‘survival of the fittest’, but rather by the ‘arrival of the frequent’.”

They found that males on average have larger total brain volumes than women (by 8 to 13 percent). Looking more closely, the researchers found differences in volume between the sexes were located in several regions. These included parts of the limbic system, and the language system.”

Male infanticide leads to social monogamy in primates“The origin of social monogamy in primates is best explained by long lactation periods caused by altriciality, making primate infants particularly vulnerable to infanticidal males. We show that biparental care shortens relative lactation length, thereby reducing infanticide risk and increasing reproductive rates. These phylogenetic analyses support a key role for infanticide in the social evolution of primates, and potentially, humans.” – h/t heartiste!

Ethnic diversity’s ‘inconvenient truths’“[W]hen the Vancouver Foundation recently conducted a massive survey of Metro Vancouver residents, researchers discovered most people in this West Coast city feel unusually high levels of loneliness and lack of friends…. The Vancouver Foundation survey of 3,800 diverse Metro residents confirmed Putnam’s results. It found one in four Metro residents feels alone more often than they would like, one-third consider Vancouver a difficult place to make friends, most don’t socialize with their neighbours, half don’t volunteer and most feel that, while diversity is generally a good thing, they prefer to be with members of their own ethnic group.” – h/t mike anissimov!

Rainforests in Far East shaped by humans for the last 11,000 years“New research shows that the tropical forests of South East Asia have been shaped by humans for the last 11,000 years.

How HBD Will Make you a Better Person“[F]orbidden knowledge does not result in genocide. The problem with this view is that genocide has been the norm throughout human history — that is, until very recently. On a historical timeline, our recent scientific knowledge of racial differences actually negatively correlates with the historic trend of genocide.” – @occam’s razor.

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.

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!

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.”

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.

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!
