Hmmm https://www.counterpunch.org/2014/02/07/where-did-white-people-come-from/ Scholars had earlier argued that blue eyes had appeared as the result of a genetic mutation somewhere between 10,000 and 6000 years ago. (Before that all humans had brown eyes.) But until a few years ago most supposed that the appearance of white skin had occurred much earlier. The European gene pool with its light complexion was supposed to have decisively “split off” from the (also light-skinned) East Asian gene pool by around 50,000 years ago, after which homo sapiens first appeared in Europe, then in China. https://ancienteuropeansinamerica.blogspot.com/2013/04/it-has-long-been-thought-that-native.html?m=1
