I think the article is bogus but then, if you actually study or read this sort of thing, and I do, humans didn't dominate the whole earth back then. It was touch and go. One of the pieces I read said that the entire human population back around then, got down to 17. It was a piece out of the Smithsonian so I give it some credence. On the Gripping Hand, it's late and I might be off by 30,000 years.
