Not a fact anymore

The earliest human ancestors originated in Europe or Asia rather than Africa.

What we know now

The earliest known hominins and the first several million years of human evolutionary history are African. Homo later dispersed repeatedly into Eurasia, where additional human lineages evolved.

Why it changed

European and Asian fossils were discovered and promoted before Africa had been comparably explored, encouraging Eurasian origin models. African australopithecines, older hominins, comparative anatomy, and genetics shifted the center of evidence to Africa.

Darwin had suggested an African origin for humans in 1871, based partly on our relationship to African apes. But the early fossil record did not make Africa the obvious center of the story. Important human fossils were being found in Europe and Asia, while much of Africa remained paleontologically unexplored.

That imbalance supported influential Eurasian origin models. Some researchers expected the crucial transitional forms to come from Europe or Asia, where fossils such as Neanderthals, Homo erectus from Java and later discoveries seemed to offer tangible evidence.

The 1924 Taung Child began shifting the geography. Raymond Dart identified the small South African skull as an australopithecine with a mixture of ape-like and human-like traits. Later discoveries across eastern and southern Africa produced multiple early hominin species, many far older than the Eurasian forms then known.

The fossil pattern is now clear at broad scale: the first several million years of hominin evolution are African. Genetic evidence likewise places the deepest ancestry of living humans in Africa.

This does not make Eurasia irrelevant. Homo dispersed out of Africa repeatedly, and Eurasian lineages such as Neanderthals and Denisovans later contributed ancestry to some living people. The correction concerns the deep origin of the human lineage, not every later chapter.
