I hope that's not all you had in mind when you wrote your comment. All of that shows no proof that it's the genetics that propels the disproportionate level of intellectual achievement. Both of those cases can easily be explained by sociocultural influences within families of various races propelling more intellectual endeavors, and if you don't have peer reviewed references showing otherwise it's probably a good idea to stop thinking that way.
>Ever since torsion dystonia among the Ashkenazim was first recognized, observers have commented on the unusual intelligence of patients. Flatau and Sterling (Eldridge, 1976) describe their first patient as showing ‘an intellectual development far exceeding his age’, and their second patient as showing ‘extraordinary mental development for his age’. At least ten other reports in the literature have made similar comments. Eldridge (1970, 1976) studied fourteen Jewish torison dystonia patients:
Quite, and sociocultural influences are why long distance running is dominated by East Africans and to an even more absurd degree by the Kalenjin, an ethnic group of less than five million people who take more than a third of top three places in competitive marathon running worldwide. Sociocultural influences are also obviously why there have been at most two men not primarily of West African ancestry who ran 100m in under 10s, and almost 70 men of that ancestry who did. Sociocultural influences must also be why the Dutch are the tallest people in the world. They really, really want to be tall and that explains their height.
