The idea that modern people
evolved in a single "cradle of humanity" in East Africa some 200,000
years ago is no longer tenable, new research suggests.
Fossils of five early humans have
been found in North Africa that show Homo sapiens emerged at least 100,000
years earlier than previously recognised.
It suggests that our species
evolved all across the continent, the scientists involved say.
Prof Jean-Jacques Hublin, of the
Max Planck Institute (MPI) for Evolutionary Anthropology in Leipzig, Germany,
told me that the discovery would "rewrite the textbooks" about our
emergence as a species.
"It is not the story of it
happening in a rapid way in a 'Garden of Eden' somewhere in Africa. Our
view is that it was a more gradual development and it involved the whole
Prof Hublin was speaking at a
news conference at the College de France in Paris, where he proudly showed
journalists casts of the fossil remains his team has excavated at a site in
Jebel Irhoud in Morocco. The specimens include skulls, teeth, and long
bones.
Earlier finds from the same site
in the 1960s had been dated to be 40,000 years old and ascribed to an African
form of Neanderthal, a close evolutionary cousin of Homo sapiens.
But Prof Hublin was always
troubled by that initial interpretation, and when he joined the MPI he began
reassessing Jebel Irhoud. And more than 10 years later he is now presenting new
evidence that tells a very different story.
