It's entirely on-topic. Many of the descendants of those people settled in Japan where they learnt to make Pentax cameras for the benefit of their travelling companions who settled in other parts of the world. > > There is one thing that strikes me as particularly amazing. > I've also seen something like this on TV in one of the > popular science shows... > > So there was this volcano eruption that left order of 10,000 > people on Earth.

It amazes me to learn how often the human race was on the verge of extinction during its early history. Even within Africa, where the genetic diversity is greatest, it is still significantly less than for other related species such as chimpanzees and gorillas. This suggests that there were some spectacular population crashes back in the old days. You might enjoy the book which was the basis of that map, and probably also of the TV programme you saw: "Out of Eden", by Stephen Oppenheimer. Bob
