A Kansas University scientist studied very old bones and found something wrong with the Eve theory.
KU anthropology professor David Frayer was part of a team that analyzed ancient skulls from around the world and found evidence that modern humans did not arise from a single migration from Africa.
Instead, there were small groups that journeyed to every continent, intermingling with archaic humans such as the Neanderthal.
The team's research was published in a January issue of the journal Science. Frayer and fellow team members from the universities of Michigan and Utah examined and compared ancient skulls from different periods from central Europe, Australia and Africa.
Their findings contradict the Eve theory, which holds that modern humans evolved in Africa and moved into the rest of the world in a singular movement.
