Somebody was on Sulawesi before 118,000 years ago – from john hawks.

Human-Neanderthal relationships may be at root of modern allergies“Three genes inherited from our Neanderthal cousins may cause modern carriers to have an overly-sensitive immune system susceptible to allergies.”

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.”

DNA sequencing reveals the fate, and ultimate extinction, of Ötzi the Iceman’s maternal genetic lineage – h/t jason moore!

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’.”

Conflict among honey bee genes supports theory of altruism – h/t steve stuart williams! who tweeted: “New genetic evidence provides strong support for kin selection theory.” – see also: Testing the kinship theory of intragenomic conflict in honey bees (Apis mellifera).

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.

Tell the truth about benefit claimants and the liberal left shuts you down“How neuro­biologist Dr Adam Perkins became a victim of the new McCarthyism.” – from toby young.

The left’s own war on science“The witch hunt against Napoleon Chagnon shows us what happens if scientists challenge the core beliefs of ‘progressives.’” – also from toby young.

Physics Has Einstein, Biology Has Darwin. Economics Has… – from david sloan wilson who tweeted: “It’s embarrassing that top economists who write about theory are clueless about evolutionary theory.”

Professors moved left since 1990s, rest of country did not – @heterodox academy.

A Single Mutation May Have Sparked Multicellular Life

Supernatural punishment: the common denominator“So here’s the question: Is religion evolutionarily advantageous…? I hypothesise that supernatural punishment was a very important promoter of cooperation and a way to reduce self-interest, which was vital to the evolution of human societies.”

Tajikistan: Lawmakers Tighten Rules on Baby-Naming, Marriage“The stricter rules on marriage have been introduced partly as a way of reducing the incidence of disabilities among children, which officials argue are the result of intensive inbreeding. Consequently, marriage among cousins and cousins-once-removed will be forbidden.” – h/t the gazillion people who sent this to me! (^_^) (#BigInTajikistan)

Women more likely than men to obey a satellite navigation system – even when it gives wrong directions – heh.

Political regimes, political ideology, and self-rated health in Europe: a multilevel analysis“Individuals with rightwing ideologies report better health than leftwing individuals…. This study shows that although both individual political ideology and contextual political regime are independently associated with individuals’ self-rated health, individual political ideology appears to be more strongly associated with self-rated health than political regime.”

Cultural Values and the Well-Being of Future Generations: A Cross-National Study“[T]he more a nation prioritized Egalitarianism versus Hierarchy values and Harmony versus Mastery values, (a) the higher was children’s well-being in the nation, (b) the more generous were national laws regarding maternal leave, (c) the less advertising was directed at children, and (d) the less CO2 the nation emitted.” (behind a paywall)

Scientific literacy by race – from the audacious epigone

First-born children are ‘more likely to suffer from allergies’“Japanese scientists found that multiple births build up the immune system in the womb which is transferred to babies. It means second and third children are less likely to suffer from hay fever or develop food allergies.”
