According to the textbooks, all humans living today descended from a
population that lived in east Africa around 200,000 years ago. This is
based on reliable evidence, including genetic analyses of people from
around the globe and fossil finds from Ethiopia of human-like skeletal
remains from 195,000–165,000 years ago.
Now a large scientific team has discovered new
fossil bones and stone tools that challenge this view. The new studies,
published in Nature,
push back the origins of our species by 100,000 years and suggest that
early humans likely spanned across most of the African continent at the
time.
