Multiregional continuity hypothesis

Assignment Help Biology
Reference no: EM1392444

Currently, three fossil skulls of Homo sapiens, dating to about 160,000 years BP, were discovered in eastern Africa. These skulls fill a gap between the 100,000-year-old H. sapiens skulls found in Africa and Israel and 500,000-year-old skulls of archaic H. sapiens found in Ethiopia. Supporters of the replacement model (out-of-Africa hypothesis) argue that this discovery strengthens their position by documenting the succession of human ancestors from 6 MYA through this most recent group. Does this finding prove that the replacement model is correct? If not, what fossil evidence might yet be found to support the multiregional continuity hypothesis?
