Homo sapiens, our own species, evolved in Africa sometime between 300,000 and 200,000 years ago. Anthropologists are pretty confident in that estimate, based on fossil, genetic and archaeological evidence.

Then what happened? How modern humans spread throughout the rest of the world is one of the most active areas of research in human evolutionary studies.
