The paper analyzes the gut microbiome of South Asian communities to show that urbanization impacts microbiomes differently across communities, with geography and culture playing a stronger role than lifestyle.

The paper compares genetic and oral histories of four Indian populations, finding genetic similarity to other Indian groups but no evidence of additional non-local genetic sources.

This study genotypes 80 Ladakh individuals to analyze genetic lineages, admixture, and adaptation, finding distinct East Asian and Indo-European affinities with signals of high-altitude and immunity adaptation.

The paper uses ancient DNA data to trace the genetic origins and spread of Indo-European languages in South and Central Asia.

This study identifies 81 unique South Asian populations with founder events leading to recessive diseases, highlighting opportunities for disease gene discovery and burden reduction.
