Scientists are sure that Homo sapiens first evolved in Africa, and we know that every person alive today can trace their genetic ancestry to there. It has long been thought that we began in one single east or south African population, which eventually spread into Asia and Europe.

What evidence suggests that modern humans originated in Africa?

What evidence is there of human behavior in Africa?
