We're Only Human, Afterall?

A group of scientists have gathered evidence refuting the simple view that our human species derived from a population that evolved in East Africa (https://www.theguardian.com/science/2018/jul/11/no-single-birthplace-of-mankind-say-scientists). A single African genesis of humans was advocated by Charles Darwin and has persisted for many years. The scientists, however, maintain that humanoids developed very differently over the entire African continent and the modern species may well have resulted from an amalgam of features produced when some of the groups eventually interbred. This seems not unreasonable as it is now clear that humanoids were involved in many migrations that pre-date existing ideas. Stone tools have recently been found in China that appear to have been made more than 2 million years ago (https://www.theguardian.com/world/2018/jul/12/stone-tools-china-could-be-oldest-evidence-human-life-outside-africa), making them the oldest evidence for human life outside Africa.
