Early Euro/Asian genetic split?

Okay, here's a discussion topic. I am interested if anyone has any papers or knowledge relating to this theory.

Okay, I was thinking about the 50% genetic split between plant omega metabolizers, and those who do so inefficiently (largely a euro/asian split). And then I put this together with out migration - half, along the coast, with fish, tubers and coconut and fruit, half inland, land mammals, tubers, greens, nuts, fruit and it clicked - those travelling inland would have needed that adaption to maintain the omega-3 needed for our brains, when animal brains were no longer eaten, or scarce. Those on the coast, would have no need for it.

Asia, polynesian genetic types, still tend to live in tropical climes, have a fish heavy traditional diet. Europeans, have an animal and plant based traditional diet largely. Sure they ate fish when it was available too, but the traditional diets seem to have this same trend. Were europeans the first dairy farmers, as consumate mammal eaters? What other splits might have occured from there? (alcohol tolerance) Is this why polynesian populations have higher rates of heart disease, diabetes etc, in response to modern western diets? What about apoB mutations, are they more common in one group or another?

I know I know, theres a slight taboo about talking about this stuff. But if there was a fundamental, early genetic split, that causes a kind of dietary specialization, and shaped adaptions from there on in, it seems like a rather major thing to be aware of, health wise.

Thoughts?

Oh god, it was a long time ago that I read the research off here about it. And my arms are currently wasted to the point I can't lift them above my shoulders (HIT strength training, first session). Ill try and google it for you tommorrow maybe.

50% approximately of the population have a gene that increases bioavailability of plant omega's, both 3 and 6. Of course the sat fat and omega-3 mylenation in our brains allowed the brain capacity increases, and demanded a high volume of omega 3 in our diet (brains or fish prettty much, at the time). This omega gene is present in europeans largely, and absent in those of asian decent. The adaption would have occured early during migration. Hence the speculation..

What is this split you talk of?

I don't have an answer for you, but I would be interested in learning about this too. Thanks for posing the question.
