New research reveals the ancestral populations of India and their relationships to modern groups | Eureka! Science News: "The one exception to the finding that all Indian groups are mixed is the indigenous people of the Andaman Islands, an archipelago in the Indian Ocean with a census of only a few hundred today. The Andamanese appear to be related exclusively to the Ancestral South Indian lineage and therefore lack Ancestral North Indian ancestry.

'The Andamanese are unique,' said co-author Nick Patterson, a mathematician and researcher at the Broad Institute. 'Understanding their origins provides a window onto the history of the Ancestral South Indians, and the period tens of thousands of years ago when they diverged from other Eurasians.'
