Quizplus · Accepted Answer

Fossil and genetic evidence strongly support the idea that all modern humans derive from a single African lineage that spread from there into other parts of the world starting about 50,000 years ago. This is known as the "Out of Africa" theory. This theory is supported by genetic studies that show greater diversity among African populations, suggesting that they have been evolving for a longer period of time. Fossil evidence also shows that anatomically modern humans first appeared in Africa before spreading to other parts of the world. While there was some interbreeding between modern humans and other hominid species like Neanderthals, this did not significantly contribute to modern human ancestry.
