Insights into Ancient Migrations and Neanderthal Ancestry in India
Research reveals that Indian populations exhibit a unique distribution of Neanderthal DNA fragments, with about 90% of known Neanderthal genome reconstructable from modern-day Indian genomes. Unique Neanderthal genetic sequences specific to Indian populations suggest potential adaptive advantages, possibly related to fighting diseases. The study sheds light on ancient migrations in India and the diverse intermingling of populations in the region.
