Intelligence polygenic scores in ancient individuals compared to modern humans. A PGS based on top significant 1402 SNPs out of 12,110 total SNPs (p value threshold p < 4 × 10−11) Afanasievo Mother z = −2.94, Afanasievo Son1. z = −2.36, Afanasievo Son2 z = −2.88, Afanasievo Father z = −1.77. Intelligence polygenic scores in Afanasievo individuals observed within 3 standard deviations (SD) from the mean of 1000 Genome Populations while Funadomari Jomon individual is above the mean, z = 0.33. B Funadomari Jomon individual, Afanasievo individuals PGS based on 9148 out of 12,110 total SNPs (p value threshold p < 5 × 10−8) extracted in common with 1000 Genome Populations. Afanasievo Mother z = −3.59, Afanasievo Son1 z = −2.45, Afanasievo Son2 z = −2.99, Afanasievo Father z = −2.04. Intelligence polygenic scores in Afanasievo individuals fell within 3 SD from the mean of 1000 Genome Populations while Funadomari Jomon individual is within 2 SD below the mean, z = −1.29
