Early Modern Homo sapiens. All people today are classified as Homo sapiens. Our species of humans first began to evolve nearly 200,000 years ago in association with technologies not unlike those of the early Neandertals. It is now clear that early Homo sapiens, or modern humans, did not come after the Neandertals but were their contemporaries.
Scientific consensus puts the earliest known ancestors of modern humans in East Africa, roughly 200,000 years ago. The first wave of humans to migrate out of Africa about 85,000 years ago followed the coasts through the Middle East, into Southern Asia via Sri Lanka, and eventually around Indonesia and into Australia.
