Here's an extract:

"A new study concludes that the earliest known humans appeared in southern Ethiopia by about
195,000 years ago, about 35,000 years earlier than previously thought, based on what researchers
say are the oldest anatomically modern human fossils ever found. Although leaving the full-
fledged arrival of Homo sapiens far from resolved, the "bombshell," as it's being called by other
scientists, suggests that roughly three-fourths of modern human evolution occurred within the
African continent."

This has implications as it narrows, to a small exent, the range of foods with which our genome
was shaped.
