>>508195336the genetic mutation which causes Blond hair/blondism has been found in DNA in bodies from the Lake Baikal area in Russia from around 30,000 years ago.
maybe people with the mutation were elsewhere earlier or somewhere else entirely and also mutated the same mutation, but as far as science can show given the data found, all blond people are descended from those Lake Baikal remains or the ancestors of those Lake Baikal remains from 30,000 years ago.
but i don't think they were mongoloid skulled people, although i can't say they were or weren't.
