India’s Genetic History

A Nature article partially tracing the genetic history of Indian populations was published September 24:

Original Nature article (abstract): Reconstructing Indian Population History – Reich et. al. – 2009

An HSPH news release: New Research Reveals the Ancestral Populations of India and Their Relationships to Modern Groups

Sounds like rich fodder for the Aryan Invasion Theory debate.  But the more serious consequence has good news and bad news: quoting from the abstract,

there will be an excess of recessive diseases in India, which should be possible to screen and map genetically

I thought the first line of the abstract is pretty important too:

India has been underrepresented in genome-wide surveys of human variation.

Hopefully said underrepresentation will cease!
