Can 3000 years be even close to being true? What about, for example, aboriginals in Australia. Is it not believed that they were an isolated population for 40,0

Can 3000 years be even close to being true? What about, for example, aboriginals in Australia. Is it not believed that they were an isolated population for 40,000-50,000 years?
- maxerickson 14y agoIt's possible. For example, if all living Australian aboriginals were to have a European explorer as an ancestor. (I'm not trying to suggest that this is the case, I'm pointing out how they could have jumped the tree, so to speak)
- prawn 14y agoWikipedia: "An explanation of this recent MRCA date is that, while humanity's MRCA was indeed a Paleolithic individual up to early modern times, the European explorers of the 16th and 17th centuries would have fathered enough offspring so that some "mainland" ancestry by today pervades remote habitats. The possibility remains that an isolated population with no recent "mainland" admixture persists somewhere, which would immediately push back the date of humanity's MRCA by many millennia. While simulations help estimate probabilities, the question can be resolved only by genetically testing every living human individual."
