And then if he gets violently ill, you know, this is not a good thing. The whole process of adapting to a new landscape Finding your way around, finding your way back, learning about it is really fascinating. And that's one of the really interesting things that has great potential in terms of the DNA.

Because one of the things that we would suspect is that when groups come into a new environment, they're going to disperse. Because more eyes in more different places, then you come back from time to time, you get together, you share information. Okay, you don't need to go in that direction. We've been there. It doesn't work.

Or we've been there and this is where you need to refurbish your stone tools. There's a wonderful geological outcrop there. This is how you deal with the animals that you're going to find there.

With ancient DNA, we can potentially identify those sort of rendezvous moments where different populations that have perhaps been separated by decades or centuries as their ancestors dispersed across the landscape, can we see them coming back together? We do know that dispersal process was in fact very, very rapid. The genomic signatures that we have in 10,000 to 12,000 years ago.

Time period in North America are very, very similar to the ones of ancient individuals in places like Southeast Brazil 10,000 years ago.

I would actually use the word stunning rather than surprising. We'd always suspected archaeologically because of the near-contemporaneity of radiocarbon dates north and south in the hemisphere.

But now we have genomic evidence that seems to, in fact, affirm that where it looks like, you know, the difference in sort of the genealogies, as it were, the genetic genealogies of these populations is that we're just talking about a limited number of generations before descendants of these groups that are in North America are already in South America.
