Haplogroups as evolutionary markers of cognitive ability

摘要: Abstract Studies investigating evolutionary theories on the origins of national differences in intelligence have been criticized basis that both cognitive ability measures and supposedly evolutionarily informative proxies (such as latitude climate) are confounded with general developmental status. In this study 14 Y chromosomal haplogroups ( N  = 47 countries) employed markers. These (most probably) not coding genes, but development potential relevance to ability. Correlations regression analyses a indicator (HDI) revealed seven were empirically important predictors (I, R1a, R1b, N, J1, E, T[+L]). Based their meaning correlation these grouped into two sets. Combined, they accounted path for 32–51% variance relative (35–58%). This pattern was replicated internationally further controls (e.g. latitude, spatial autocorrelation etc.) at regional level independent samples (within Italy Spain). findings, using conservative estimate influences, provide support mixed influence stemming from current environmental past (evolutionary) factors.
