300,000-year-old Homo Sapiens fossil found

Fossils discovered in Morocco are the oldest known remains of Homo sapiens, scientists reported on Wednesday, a finding that rewrites the story of mankind’s origins and suggests that our species evolved in multiple locations across the African continent, reports The New York Times.
“We did not evolve from a single ‘cradle of mankind’ somewhere in East Africa,” said Philipp Gunz, a paleoanthropologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and a co-author of two new studies on the fossils, published in the journal Nature. “We evolved on the African continent.”
Until now, the oldest known fossils of our species dated back just 195,000 years. The Moroccan fossils, by contrast, are roughly 300,000 years old. Remarkably, they indicate that early Homo sapiens had faces much like our own, although their brains differed in fundamental ways.
Today, the closest living relatives to Homo sapiens are chimpanzees and bonobos, with whom we share a common ancestor that lived over six million years ago. After the split from this ancestor, our ancient forebears evolved into many different species, known as hominins.
For millions of years, hominins remained very apelike. They were short, had small brains and could fashion only crude stone tools.
Until now, the oldest fossils that clearly belonged to Homo sapiens were discovered in Ethiopia. In 2003, researchers working at a site called Herto discovered a skull estimated to be between 160,000 and 154,000 years old.
A pair of partial skulls from another site, Omo-Kibish, dated to around 195,000 years of age, at the time making these the oldest fossils of our species.
Findings such as these suggested that our species evolved in a small region — perhaps in Ethiopia, or nearby in East Africa. After Homo sapiens arose, researchers believed, the species spread out across the continent.
Only much later — roughly 70,000 years ago — did a small group of Africans make their way to other continents.
Yet paleoanthropologists were aware of mysterious hominin fossils discovered in other parts of Africa that did not seem to fit the narrative.
In 1961, miners in Morocco dug up a few pieces of a skull at a site called Jebel Irhoud. Later digs revealed a few more bones, along with flint blades.
Using crude techniques, researchers estimated the remains to be 40,000 years old. In the 1980s, however, a paleoanthropologist named Jean-Jacques Hublin took a closer look at one jawbone.
The teeth bore some resemblance to those of living humans, but the shape seemed strangely primitive. “It did not make sense,” Dr. Hublin, now at the Max Planck Institute, recalled in an interview.
Since 2004, Dr. Hublin and his colleagues have been working through layers of rocks on a desert hillside at Jebel Irhoud. They have found a wealth of fossils, including skull bones from five individuals who all died around the same time.
