Really? Where is your evidence that indians are predisposed genetically to abuse alchol? Their tolerance for alcohol probably has something to do with genetics since a population will adapt over generations to large consumptions of alcohol, e.g. the irish. The indians, however, were isolated for hundreds of years and were not exposed to drink, and therefore their bodies cannot now handle large amounts without falling apart. But this is a far cry from saying that a gene predisposes them to alcohol abuse. There is zero evidence for this. Human bodies will adapt over time to certain conditions, but new genes never appear. Whatever information is in the human genome was there at the beginning, only now the genome has deteriorated from what it was originally. This is quite the opposite from neodarwinian theory - which is a bunch of crapola.

I would like to see proof that as human bodies have evolved over the eons that no genetic changes take place. I don't agree with that.
BTW, I'm no Darwinist per se...quite the opposite....I see many holes in the theory of evolution from amino macid soup to today's man but that doesn't mean I don't think we have not had some genetic alteration....as opposed to waht you called "new genes".
Culture and collective behavior also play a large part in alcoholism btw.
