New preprint on South Asian population history
Broad MIT/Harvard and friends have released a new preprint at bioRxiv on the genetics of South Asians. It's titled The promise of disease gene discovery in South Asia and mostly focuses on the recent demographic histories of ethnic groups from across India. See here. In fact, it lacks any analyses with ancient genomes, which is a shame. But the supp info includes an interesting Admixture graph which shows the Paniya of South India modeled as 83% Ancestral South Indian (ASI) and 17% Ancestral North Indian (ANI). See Supplementary Figure 6. here. ANI is shown as a sister clade of present-day Georgians, which probably means that, as far as the Paniya are concerned, it's essentially an offshoot of an Caucasus Hunter-Gatherer (CHG) population.
