Ancient introgression drives wild boar expansion and phenotypic diversification of domestic pigs.

Despite the ubiquity of wild boar populations across Eurasia, their origins, routes of dispersal, and phenotypic evolution remain uncertain. Here, using 745 genomes representing populations across Eurasia, we demonstrate that wild boar expanded from South Asia during the Middle Pleistocene. This expansion was preceded...

Genetic architectures of brain-related traits are shaped by strong selective constraints

Significance A central goal of human genetics is to understand how genetic variation shapes complex traits, including height and susceptibility to diseases. Over the past two decades, genome-wide association studies (GWAS) have identified numerous trait-associated genetic variants, but the findings can differ widely ac...
