Recent scientific expeditions that have retraced all routes of human migration out of Africa in the last 50,000 years make for a fascinating story. In the exhibit perused for this exercise I discovered that the pivotal moment was the great Ice Age that set in 50 thousand years ago, up until when, the rich and diverse ecology of central and southern Africa began to change. With the substantial drop in temperatures, the erstwhile green and fertile regions began to dry up. And this crisis for survival is perhaps the most important event in anthropology.
