Not true. Australian aborigines split off 40k years ago. Now, if somehow we interbred with all of them, so that no pure aborigines are left, in a 100 years we move the line to a date that resembles what you suggest. We have to do that every remote tribe on earth. Or if for some reason they are killed.
- jltsiren 5y agoIsolated populations never remain fully isolated. If Aboriginal Australians managed to reach Australia tens of thousands of years ago, it makes no sense to assume that nobody ever followed them. It's far more likely that there was constant low-level contact with Austronesian peoples – even if it didn't occur in every generation or every century. And it's also quite likely that some lost sailors ended up in Australia over millennia, and some of them had children. If the level of contact is low enough, it won't leave any measurable genetic traces. After all, if you go back sufficiently many generations, most of your biological ancestors are not your genetic ancestors.
- irrational 5y agoAre you saying not true without even reading the studies, speaking from scientific knowledge, or speaking off the cuff?
- abc_lisper 5y agoI was wrong. Just checked Dawkins’ “ancestor tale”.
