For a long time, theories of evolution centred around the idea that an early species called Homo erectus began dispersing from Africa between 1.5 million to two million years ago.
Under that theory, other early humans stayed put in Africa, where they eventually died out.
Under that theory, other early humans stayed put in Africa, where they eventually died out.
But the theory has been challenged by discoveries in recent years of species that do not appear to be descended
In particular, the teeth they found had a surprising combination of elements from different early humans.
