By way of breaking cover, and via dave Faber’s IP list, here is something rather wonderful. Its a very smart flash animation showing 150,000 years of human migration across the planet – from our origins in East-central Africa to the ‘present’ of the last few thousand years.

Although I am familiar with the route these people (we!) took from books like Guns, Germs, and Steel, the animation really makes it clear. I learned a lot from this. Definitely worth a look!
