Proof questions out-of-Africa theory

摘要

The "Out of Africa" theory suggests that modern humans evolved from Africa and then spread throughout the earth about 70,000 years ago, replacing earlier humans with little or no interbreeding. But recent research on the remains of an early modern human (EMH) recovered in Tianyuan Cave in southwest suburb of Beijing indicates that the EMH dispersal from Africa to Asia is not that simple asrnpreviously thought.
