Genomic inferences on peopling of south Asia.

South Asia has been a major corridor for the geographic dispersal of modern human from out-of-Africa to other regions of the world. Genomic markers have provided key information for tracing trails of human migration. An overall view of these trails has emerged, though there are still many contentious issues. The nature of genomic differentiation in south Asia is high, resulting from a combination of admixture and isolation.
