In particular, it seems<BR>> that the ability to digest milk in adulthood arose and spread to most of the<BR>> species. Also, blondness seems to have arisen in the last six thousand years<BR>> ago. Granted, these are minor changes, but there are probably others that<BR>> just haven't been uncovered as of yet.<BR><BR>Yes for the general picture, but I would object to a few details.<BR><BR>- Ability to digest comfortably lactose in adulthood seem only concern some 90%+ of Europoids and 50% of some populations of East Africa (because of
entirely different mutations!) so it is far from generalised in our species.<BR><BR>- Fair pigmentation (blond or red hair, blue or gray eyes) is a recessive feature which but for albinism exists only in the Europoid race for our species (it would appear that Neanderthals were red-headed), and should come out from the genetic drift which affected the small groups of Sapiens which survived the last Great Ice Age, sometime around 10-12000 bC<BR><BR>- It seems on the other hand that some mutation arisen in 6000 bC has spread in our species, against from Europe, which may offer cognitive improvement dividends. <BR><BR>See, inter alia, <A class=yiv880100771title href="http://www.amazon.com/Before-Dawn-Recovering-History-Ancestors/dp/014303832X/ref=sr_1_1?s=books&ie=UTF8&qid=1311959172&sr=1-1" rel=nofollow target=_blank>Before the Dawn: Recovering the Lost History of Our Ancestors</A> <SPAN class=yiv880100771ptBrand>by <A
