Humans in Europe

I saw that earlier, and I'm scratching my head about it. The scholarship, as I understand it, says that the earliest homo sapiens to come out of Africa did so somewhere between 90 and 60 thousand years ago. But this is putting human beings in Britain around 800 thousand years ago. The Nature article gives bounds of between 814 and 970 thousand years. That's still vastly longer ago than anything I've seen, and yet they also go on to say that they had evidence of people there ~700 thousand years ago before this find. The author does speculate that this could be Homo antecessor, an ancestor of Homo sapiens, which might explain one mystery. But it still leaves me asking what was going on that Homo sapiens would only develop in Africa.

It's not as if we don't have mysteries in physics and astronomy. We do. But I can't think of anything as obviously inconsistent as this.
