Thanks, Jim. I'll think about that.

India presents an excellent population to study these issues. Brahmins are almost European in features-I suspect genetic analysis will show conserved "Y" lineages that homologize with EuroDNA, while the mtDNA is all over the place.

It may be premature to study Africa and Africans-for many reasons.

I think a detailed study of aboriginal Australians, polynesians, Han Chinese and Indonesians would be very interesting, and might speak to your issue about how variable phenotype can be with a common genotype.
