And as a physician, I would like to comment further that Tay-Sacks and Sickle Cell and other diseases that have a genetic component can jump across the cultural divide sometimes called race or emerge independently in other ethnic, cultural, regional, and family lines. 3 out of 1,000 children from two white parents are born with Sickle Cell trait. Slightly less from two Asian parents.
Race, if being most generous to the idea, could be scientifically analogous to a "breed" of dogs or cats, except the variability is significantly greater in the groupings humans have made of themselves, and I hesitate to give any credence to the idea of the superiority of any "pure line". |
