Cover picture: A market seller in Yakutsk, capital of the Siberian region of Yakutia, offers an Arctic hare for sale in addition to deep-frozen fish. Yakutsk is the coldest city (population > 100,000) on Earth, with an average winter temperature of -38ºC, and the only one of comparable size to be built on permafrost.

MANKIND QUARTERLY 2017 57:4 482-486 Editorial Archaeogenetics: (Pre-)history Goes Molecular One year ago, in the Summer 2016 issue of Mankind Quarterly, I wrote an editorial drawing the reader’s attention to a “paradigm shift” in the social sciences, triggered by the discovery of genetic variants associated with educational attainment. Three large meta-analyses of genome-wide association studies (GWAS) had reported about one hundred regions in the genome in which common genetic variants (single-nucleotide polymorphisms, SNPs) are statistically associated with educational attainment. Each of these regions is inferred to contain a gene, with common variants in the gene affecting the chances of staying in school or earning an educational degree. It was obvious that suddenly, studies were becoming possible that had been unthinkable only a few years earlier. What happened to this “scientific revolution” during the last year? Did it produce any dramatic new insights, or was it all hype? At the time, we already had first results from the United States showing that family advantage and social mobility are driven in part by “educational attainment genes” that children have inherited from their parents (Domingue et al., 2015). Could these results be confirmed in further studies? The most relevant new insights have come from a relatively small (N = 919) but thorough study in New Zealand (Belsky et al., 2016). It showed that a polygenic score for educational attainment was associated with numerous outcomes: (1) As expected, it predicted attainment of higher educational degrees. The effect was weak (r = .15), with a 19% increased risk of a university degree for a one standard deviation rise in polygenic score. (2) Children with higher polygenic scores showed accelerated cognitive development, had better self-control and better interpersonal skills. (3) Adult attainment was higher: more prestigious occupations, higher income, more accumulated assets, less welfare benefits, and higher credit scores. Only half of this was mediated by educational attainment. Thus the traits that are related to this polygenic score affect life outcomes not only by raising educational credentials. (4) Those with higher polygenic scores tended to come from families with higher socio-economic status, but higher polygenic scores were associated with upward social mobility for those from lower socio-economic backgrounds. (5) Adults with higher polygenic scores were more likely to emigrate or to have worked abroad. These results show compellingly that genetic variants predict many social outcomes, although with very low accuracy. 482 EDITORIAL How do the genes affect these outcomes? Small effect sizes make studies of individual SNPs difficult, but the top SNP in the Rietveld et al. (2013) study turned out to be associated with verbal ability, with each allele contributing about 1.4 points to the verbal IQ (Gunnarsson et al., 2016). Therefore, this particular variant is an “IQ gene” that causes a verbal IQ difference of 2.8 points between the two homozygotes. More recent genome-wide association studies are finding “IQ genes” not by studying education-associated SNPs, but directly by genotyping subjects for whom IQ test scores have been obtained. The most recent study, based on results from 78,308 subjects, reports IQ-associated variants in 18 genomic regions, and an additional 30 genes that came out significant in gene- based analyses (Sniekers et al., 2017). Genetic traits change their frequencies across generations through mutation, selection and random drift. Therefore the question arises of whether the frequencies of those genetic variants that contribute to individual differences in intelligence, personality or education have changed recently in human evolution. The question is, in particular, whether the long-term trend of rising cultural complexity is related not only to sporadic innovations and their cultural transmission, but also to changing frequencies of those genetic variants that make people capable of innovation and cultural transmission. The first approach to this question was based on comparisons of allele frequencies for “educational attainment genes” and “IQ genes” in living human populations.
