Nature Communications paper-Evidence of the interplay of genetics and culture in Ethiopia

This paper shows evidence of associations between social behaviours and genetic differences among present-day Ethiopian people. It is shown that genetic similarity is broadly associated with linguistic affiliation but also identifies pronounced genetic similarity amongst groups from disparate language classifications that may in part be attributable to recent intermixing. Groups reporting the same cultural traits are more genetically similar on average and show evidence of recent intermixing, suggesting that shared cultural traits may promote admixture.
