6,000 years, eh?
From my own work, I have dated human remains going well over 7,500 years ago. They're trying to get mtDNA from them now.
Want to bet whether they show continuity to more recent skeletons and living descendants from that same area?
Or, if there was a flood some 4,350 years ago that wiped out all life except Noah and his kin, there could not be a continuity of mtDNA types--the mtDNA in more recent populations would have to be middle-east types, all spread worldwide by descendants of Noah et al.
Any bets on what the evidence will show?
