flag Researchers map Indian genomes, finding ancient ancestry sources and high risks of genetic disorders.

flag Researchers mapped the genomes of 2,762 Indians, identifying three main ancestry sources: ancient hunter-gatherers, Iranian farmers, and Eurasian pastoralists. flag The study highlights a high risk of recessive disorders due to community-specific marriages. flag It also found up to 1.5% of the genome linked to Neanderthals or Denisovans, suggesting adaptive advantages. flag In related research, the Sinhalese of Sri Lanka were found to have migrated from South India and mixed with local Adivasi populations, contradicting earlier theories of a Northern Indian origin.
