Human evolution was messy and gradual, not an abrupt revolution, argues archaeologist

It is generally accepted by archaeologists that modern humans originated in Africa and dispersed worldwide, while other hominins went extinct. Yet how and when Homo sapiens dispersed out of Africa, and whether it was an abrupt event, is still debated. Even more uncertain is how and when humans went from being "archaic" to "modern."
