According to the RSOH, anatomically modern humans evolved in Africa between 200,000 to 100,000 years ago, with members of one branch leaving Africa about 80,000 years ago. These emigrants spread to the rest of the world; it means all modern humans originated in sub-Saharan Africa:
New research published in the journal Nature (19 July) has proved the single origin of humans theory by combining studies of global genetic variations in humans with skull measurements across the world. The research, at the University of Cambridge and funded by the Biotechnology and Biological Sciences Research Council (BBSRC), represents a final blow for supporters of a multiple origins of humans theory.
Competing theories on the origins of anatomically modern humans claim that either humans originated from a single point in Africa and migrated across the world, or different populations independently evolved from homo erectus to home sapiens in different areas.
However there is a debate going on over human origins. Some experts can’t agree on new findings:
John Hawks of the University of Wisconsin-Madison says the paper is “mistaken.†A major flaw is that the current research is largely based on skull variability.
Nevertheless this is interesting news for all of us, as it through out some light on where we came from.
