The paper analyzes haplogroup R30 in South Asia to trace human dispersal, finding it originated in the Indian subcontinent ~50 kya and shows evidence of multiple migrations.

This study identifies a fourth ancestral component in Dravidian-speaking tribes, suggesting a Proto-Dravidian ancestry originating around 4,400 years ago, distinct from other known sources.

GHIST 2024 evaluates population genetic inference methods through four demographic history challenges, revealing the dominance of site frequency spectrum-based methods and the potential of flexible models for complex histories.

The paper analyzes maternal genetic diversity in the Konkani population of India using mitogenomes, revealing distinct haplogroups and historical migration patterns.

This study uses Y chromosome STR variation from Indian and Eurasian males to show that Neolithic agricultural expansion shaped the male gene pool, with haplogroups F, L, and R1a associated with hunter-gatherer, agricultural, and priestly groups respectively.

This study analyzes genetic admixture and adaptation in South West coast India populations, revealing distinct lineage and early migration patterns from North West India.
