Whole-genome sequencing of 2,762 Indians has unravelled the layers of ancestry, high intermixing with Neanderthals and Denisovans — which allowed the reconstruction of roughly half of the Neanderthal genome and one-fifth of the Denisovan genome using only Indian genomes — and high endogamy in India resulting in harmful mutations in some groups.
