Last 10 years of research has provided substantial information about the Negrito populations living in South and Southeast Asia. Here with the current state-of-art we provide solid evidence for spatial and temporal admixture of Andaman Islanders.
The spatial and temporal settlement of the Andaman Island by the Negrito populations is a matter of intensive debate. In absence of any substantial archaeological evidence so far, most of the hopes were seeking the insight from genetics. However, the genetics studied till date have arrived at conflicting conclusions. It is not clear that when this island was populated and how the present Negrito populations living here share their ancestry with the other modern as well as archaic humans? We have analysed the genomewide data of more than 300K SNP with the available current state-of-art. We found an initial early split of these populations with the Oceanians and Australians, followed by various degree of admixture at different timescale with other Negrito groups.
