These are from Michael Wood’s BBC documentary. I have been searching for
his descriptions through anthropologists, historians and Vedic
scholars. They do not concur with Wood’s opinion. Apparently it
appears to be just Michael Wood’s opinion. I think Wood just spiced up
his presentation.
Interestingly the same Y-chromosome haplogroup is shared by both the
Bhat brahmin community (Mangalore region; >60%) and Adivasis (18%) in
Madya Pradesh. Similar studies have emerged for communities in other
states of India. The picture we get is at a molecular level we are a
blended group, yet exhibit outward differences. The body of information
regarding Y-chromosome (the project started just five years ago, but an
earlier study goes back to 1992) is still evolving, and in a few years
we would have a much richer knowledge of human migration patterns.
BTW, the so called Y-M9 was found in Theni (west of Madurai) which is
shared by the Australian aborigines. It was a major discovery when
announced a few years ago, linking Africa to Australia.
