Now we're... thinking about 30,000 years ago. We've got the White Sands discovery, which seems to be holding its own. There were detractors at the start, but then there were rebuttals. These are the things... I've seen this happen way too many times. You get an amazing discovery, but then somebody shoots it down, and then it wasn't that way.

But the White Sands thing, which is 23,000, that one's holding pretty strong. So, archaeologically... Our cap is now 23,000. In terms of DNA studies, they're saying that You know how we can, I mean, those people in lab coats can figure out when things mutate. They're saying that the earliest DNA in the Americas started to change and isolate about 33,000 years ago.

And now the weird number that nobody believes is more like 60. Wow. What do you mean when you say change and isolate? We still believe that humans came across the Bering Strait when it was Beringia. And that, over a period of thousands of years, opened and closed and opened and closed. The last time it opened as a corridor that people could walk across was about 12,000 years ago.

Then it melted and it's been water ever since.

Not necessarily. I mean, I do believe that there was something that happened then. I don't know what humans were doing at that time and how much it impacted them. You know, I'm not a geomorphologist. That Younger Dryas thing has become so hotly contested.

I think it crept up from Antarctica, but places like, you know, certainly things within the tropics never iced up.

It would have a different shape, for sure. There's a shelf that drops off steeply into the Pacific, almost the whole coast.
