A friend seny me the above clip. Some comments:
* The affect, style, and mannerism is very familiar to me. It reminds me of Muslim and Christian Creationist public speakers, who exhibit an air and manner of incredible confidence to audiences who want what they have on offer. Validation. Confirmation.
* The citations of the scholarly literature indicate that the theories of are based on some provisional work…but notice the shift from provisionality to refutation and vindication in the presentation. Just because it is in peer-reviewed journals does not mean it is true.
* Civilization comes from India is the conclusion. The above speaker is sophisticated and intelligent, but the ultimate rub is the same as Indocentric fabulists of the past.
In the past few years, genetic evidence on human differences has become more obvious. The reaction, in the West, is to declare even more strongly that no differences exist, or even could exist. Westerners and Indians are probably very similar, at least the activist sorts that consider these sorts of issues. In the near future, a substantial amount of ancient DNA will be published in India which will resolve current questions to all those approaching it with an open mind. But the ideologues will become even more strident and marshal greater and greater numbers of irrelevant citations.
They believe because it is absurd.
