The New York Times has posted an article entitled Still Evolving, Human Genes Tell New Story. The article contains this tid bit:
Dr. Pritchard estimates that the average point at which the selected genes started to become more common under the pressure of natural selection is 10,800 years ago in the African population and 6,600 years ago in the Asian and European populations...
Skeletons similar in form to modern Chinese are hard to find before that period, Dr. Klein said, and there are few European skeletons older than 10,000 years that look like modern Europeans...
Dr. Pritchard's list of selected genes also includes five that affect skin color. The selected versions of the genes occur solely in Europeans and are presumably responsible for pale skin. Anthropologists have generally assumed that the first modern humans to arrive in Europe some 45,000 years ago had the dark skin of their African origins, but soon acquired the paler skin needed to admit sunlight for vitamin D synthesis.
The finding of five skin genes selected 6,600 years ago could imply that Europeans acquired their pale skin much more recently. Or, the selected genes may have been a reinforcement of a process established earlier, Dr. Pritchard said.
Now this is a very important. See if Europeans didn't become white until 6,600 years ago then they were black during the time of early Dynastic Egypt! After all 6,600 years ago places us at BC 4594. which is around the time of the first Dynasty of Ancient Kmt. In fact if we read Diop we find that the ancient khemites had already been developing accurate calendars before white people even existed as we know them. We hd certainly already been developing complex religions. We had been domesticating animals and building complex structures. We had been developing what would later be called Chemistry.
It would seem then that when folk refer to white peolpe as "Johny Come Lately" it really really is the case.
