Million year hominid dispersal event in Iberia“Archaeological remains dating to between 1 million to 780,000 years were also found on an excavation that has provided evidence of the first known human occupation in the Iberian Peninsula.” – h/t cultevobot!

Early Exit: When Did Modern Humans First Leave Africa?“[A] recent study in Proceedings of the National Academy of Sciences of the genes of indigenous people in southeast Asia has suggested a much earlier date for the first human explorers. Professor Katerina Harvati-Papatheodorou and lead author Hugo Reyes-Centeno of the University of Tubingen in Germany and their colleagues fed this genetic data into a computer model of migration and found that the best explanation was an African exodus around 130,000 years ago, more than twice as far back as most scientists think. They also suggested that this early wave took a different route, spreading along the south coasts of Arabia and Asia towards Australia.”

Early modern humans were ‘culturally diverse’ before they left Africa“Researchers have carried out the biggest ever comparative study of stone tools dating to between 130,000 and 75,000 years ago found in the region between sub-Saharan Africa and Eurasia. They have discovered there are marked differences in the way stone tools were made, reflecting a diversity of cultural traditions. The study has also identified at least four distinct populations, each relatively isolated from each other with their own different cultural characteristics.”

Indo-Europeans preceded Finno-Ugrians in Finland and Estonia“An archaic (Northwest-)Indo-European language and a subsequently extinct Paleo-European language were likely spoken in what is now called Finland and Estonia, when the linguistic ancestors of the Finns and the Sami arrived in the eastern and northern Baltic Sea region from the Volga-Kama region probably at the beginning of the Bronze Age.” – @dienekes’.

The Most Violent Era In America Was Before Europeans Arrived“[A] new paper finds that the 20th century, with its hundreds of millions dead in wars and, in the case of Germany, China, Russia and other dictatorships, genocide, was not the most violent – on a per-capita basis that honor may belong to the central Mesa Verde of southwest Colorado and the Pueblo Indians. Writing in the journal American Antiquity, Washington State University archaeologist Tim Kohler and colleagues document how nearly 90 percent of human remains from that period had trauma from blows to either their heads or parts of their arms. ‘If we’re identifying that much trauma, many were dying a violent death,’ said Kohler. The study also offers new clues to the mysterious depopulation of the northern Southwest, from a population of about 40,000 people in the mid-1200s to 0 in 30 years.” – h/t hbd bibliography!

The ‘six universal’ facial expressions are not universal, cross-cultural study shows“It’s a con­cept that had become uni­ver­sally under­stood: humans expe­ri­ence six basic emotions — happiness, sad­ness, anger, fear, dis­gust, and surprise — and use the same set of facial move­ments to express them…. The only problem with this con­cept, according to North­eastern Uni­ver­sity Dis­tin­guished Pro­fessor of Psy­chology Lisa Feldman Bar­rett, is that it isn’t true at all…. [W]hat were assumed to be ‘psy­cho­log­ical uni­ver­sals’ may in fact be ‘Western’ — or per­haps even ‘American’ — cultural cat­e­gories.”

The intelligent pursuit of happiness“Intelligence is associated with health and longevity, and more intelligent children on average tend to live longer and healthier lives than less intelligent children, although it is not known why. Health is significantly associated with psychological well-being. So, it is possible that more intelligent individuals are more stable in their happiness over time because they are more likely to remain constantly healthy than less intelligent individuals.” – from dr. james thompson.

Clues emerge to genetic architecture of intelligence in children“‘When we computed the contribution of common variants to these cognitive abilities, we found that some of the contributions were substantial,’ said Hakonarson. For instance, common SNPs accounted for roughly 40 percent of the population differences in nonverbal reasoning, and 30 percent of the differences in language reasoning, with the balance of the differences attributable to rare variants and environmental factors. On the other hand, common gene variants together contributed to only 3 percent of the differences in spatial memory—the ability to navigate in a geographical location. There also were significant overlaps between trait domains. Reading ability, which was 43 percent attributable to common variants, was often inherited together with language reasoning abilities.” – h/t nolasco!

Lead released from African cookware contaminates food“Researchers tested 29 samples of aluminum cookware made in Cameroon and found almost all had considerable lead content. This cookware is common throughout Africa and Asia and is made from recycled scrap metal including auto and computer parts, cans, and other industrial debris.

Getting the babes but not the babies“Who’s making more babies? ‘Good boys’ or ‘bad boys’? Originally, the good boys were, thanks to parental monitoring of relations between single men and single women. The pendulum then swung toward the bad boys in the 1940s, only to swing back after the 1960s.” – from peter frost.

Is empathy in humans and apes actually different? ‘Yawn contagion’ effect studied“Humans and bonobos are the only two species in which it has been demonstrated that yawn contagion follows an empathic trend, being more frequent between individuals who share a strong emotional bond, such as friends, kin, and mates…. Two features of yawn contagion were compared: how many times the individuals responded to others’ yawns and how quickly. Intriguingly, when the yawner and the responder were not friends or kin, bonobos responded to others’ yawns just as frequently and promptly as humans did. This means that the assumption that emotional contagion is more prominent in humans than in other species is not necessarily the case. However, humans did respond more frequently and more promptly than bonobos when friends and kin were involved, probably because strong relationships between humans are built upon complex and sophisticated emotional foundations linked to cognition, memory, and memories. In this case, the positive feedback linking emotional affinity and the mirroring process seems to spin faster in humans than in bonobos. In humans, such over-activation may explain the potentiated yawning response and also other kinds of unconscious mimicry response, such as happy, pained, or angry facial expressions.”

Self-regulatory failure and the perpetration of adolescent dating violence: Examining an alcohol use by gene explanation“[A]lcohol use was more strongly associated with dating violence among adolescents who had a high rather than a low multilocus genetic profile composed of five genetic markers that influence dopamine signaling. Alcohol use was more strongly related to dating violence among boys with long rather than short 5-HTTLPR alleles, the opposite of the prediction. MAOA-uVNTR did not interact with alcohol, but it had a main effect on dating violence by boys in later grades in the expected direction: boys with more low activity alleles perpetrated more dating violence. Exploratory analyses found variation in findings by race.” – h/t unsilenced science!

The recently released document also includes sexual advice for couples, especially for the ‘first night.’ ‘Consanguineous marriage is mostly among first-degree relatives, increasing the number of rare genetic diseases,’ it said. ‘This matter is noteworthy. Those who are married to kin and those who carry genetic diseases should consult a health institution before gestation.'” – h/t anatoly karlin!

Avoiding Prince Joffrey: Primates have newly discovered ability that stops inbreeding“[N]ew research in macaques has revealed for the first time that primates are able to recognise their own relatives. The researchers opted for macaques rather than chimps for their study as the former lives in larger groups with more relatives; allowing them to pick distantly related monkeys who haven’t met, they could rule out ‘familiarity’ as a way for figuring out who is related…. The researchers had no clue as to how they were able to do this. Perhaps they did make a ‘template’ based on relatives they were familiar with, or maybe they had figured out what they looked like somehow, so could use that to figure out who were their relatives.”

Fate of new genes cannot be predicted“New versions of genes, called alleles, can appear by mutation in populations. Even when these new alleles turn the individuals carrying them more fit to survive and reproduce, the most likely outcome is that they will get lost from the populations. The theory that explains these probabilities has been postulated by the scientist J.B.S. Haldane almost 90 years ago. This theory has become the cornerstone of modern population genetics…. The research team … has now experimentally tested Haldane’s theory.”

‘Love hormone’ may play wider role in social interaction than previously thought“The new study, to be published Sept. 12 in Nature, pinpoints a unique way in which oxytocin alters activity in a part of the brain that is crucial to experiencing the pleasant sensation neuroscientists call ‘reward’…. ‘People with autism-spectrum disorders may not experience the normal reward the rest of us all get from being with our friends….’ Some genetic evidence suggests the awkward social interaction that is a hallmark of autism-spectrum disorders may be at least in part oxytocin-related. Certain variations in the gene that encodes the oxytocin receptor – a cell-surface protein that senses the substance’s presence – are associated with increased autism risk.”

Research suggests that humans are slowly but surely losing intellectual and emotional abilities“With the development of agriculture, came urbanization, which may have weakened the power of selection to weed out mutations leading to intellectual disabilities. Based on calculations of the frequency with which deleterious mutations appear in the human genome and the assumption that 2000 to 5000 genes are required for intellectual ability, Dr. Crabtree estimates that within 3000 years (about 120 generations) we have all sustained two or more mutations harmful to our intellectual or emotional stability.”

Mongolia and the Altai Mountains: Origins of genetic blending between Europeans and Asians“[T]his blending was not due to an eastward migration of Europeans, but to a demographic expansion of local Central Asian populations, thanks to the technological improvements the Scythian culture brought with them.”

How Do You Raise a Prodigy?

Children suffer effects of parents’ divorce into adult life“The children of divorced parents can suffer the effects of the break-up well into their adult life, a report has found.”

Culture: Diverse diagnostics“Perhaps the most dramatic demonstration of this is a study of more than 55,000 children in South Korea, which estimated autism prevalence at 2.64%. That’s more than twice the autism prevalence in the United States estimated by the US Centers of Disease Control and Prevention, and more than 50 times higher than the South Korean government’s figure for autism prevalence of 0.046%. One reason for that higher estimate may be that the researchers screened children in the general population for autism symptoms, rather than recruiting them only from clinics for autism and other developmental disorders.”

Does cloudy weather make you ginger?“Provisional statistics indicate that between two and six per cent of northwest Europeans are redheads, compared to an average of one or two per cent in the world population. But in the UK the numbers are much higher, with 13 per cent of Scots, 10 per cent of the Irish, and six per cent of individuals in England having read hair.”

Hacking the President’s DNA“The U.S. government is surreptitiously collecting the DNA of world leaders, and is reportedly protecting that of Barack Obama…. In the not-too-distant future, they may provide … the basis for the creation of personalized bioweapons that could take down a president and leave no trace.”

Racial differences in narcissistic tendencies“Study 1 (N = 367) found that Black individuals reported higher levels of narcissism than White individuals even when controlling for gender, self-esteem level, and socially desirable response tendencies.” – @steve sailer’s.

Genomics: The single life“‘In recent years we’ve learned that there is considerable variation in the recombination rate between different populations, between the sexes and even between individuals.'”

Moment Magazine’s great (Jewish) DNA experiment“Moment Magazine … wrote about their Great DNA Experiment, in which they look at the 23andMe results of 15 notable Americans of Jewish ancestry and make some interesting genetic connections…. The piece shows it’s not ‘six degrees’ that separates these individuals from each other, but, in all but one case, no degrees of separation.” – @race/history/evolution notes.

Are the cads outbreeding the dads?“Is natural selection now favoring the ‘cads’ over the ‘dads’?” – god, i hope not! – from peter frost.

Is there an upside to anxiety?“[S]ocial anxiety – the fear of interactions with strangers – may have evolved to enable a natural social ranking system in which some people feel most comfortable towards the bottom of the totem pole. This natural shuffling would have made for a less aggressive, more survivable living situation and reduced fighting for leadership.”

Young Children Are More Generous When Others Are Aware of Their Actions“Adults frequently employ reputation-enhancing strategies when engaging in prosocial acts, behaving more generously when their actions are likely to be witnessed by others and even more so when the extent of their generosity is made public…. Children were consistently generous only when the recipient was fully aware of the donation options; in all cases in which the recipient was not aware of the donation options, children were strikingly ungenerous…. These findings suggest that long before they develop a rich understanding of the social significance of reputation or are conscious of complex strategic reasoning, children behave more generously when the details of their prosocial actions are available to others.”
