Human fossils discovered in Morocco sheds light on origins of mankind
Anthropologists have long sought to pin down the exact location of the proverbial “Garden of Eden” — the region of our planet where the earliest Homo sapiens emerged.
Over the past two decades, a combination of genetic evidence and data from the fossil record led scientists to conclude that the first members of our species evolved in Eastern Africa about 200,000 years ago.
But a new discovery suggests a more complex narrative for the origin of humans.
In a pair of papers published Wednesday in Nature, an international team of researchers describe 22 human fossils from northwest Morocco that are approximately 300,000 years old.
According to the authors, it is the earliest evidence of Homo sapiens ever discovered — by a long shot.
The unexpected location of the find, coupled with previous discoveries of early human remains dating back to 260,000 years in South Africa and 195,000 years in Ethiopia, cast doubt on the story that the first members of our species evolved in a single region of the African continent, study authors said.
“Our results challenge this picture in a number of ways,” said Jean-Jacques Hublin of the Max Planck Institute for Evolutionary Anthropology in Germany, who led the work. “There is no Garden of Eden in Africa, or if there is a Garden of Eden, it's Africa. The Garden of Eden is the size of Africa.”
This is the first, almost complete adult mandible discovered at the Jebel Irhoud site. The shape of the bone and the teeth clearly assign it to the root of our own lineage, the study authors say.
Not all of the fossils cataloged in the papers are new discoveries. Six of the 22 specimens were first unearthed in the 1960s as the result of barite mining operations at Jebel Irhoud, the archaeological site that is located between Marrakesh and Morocco's Atlantic coast.
At the time of the initial discovery, scientists concluded that the fossils were about 40,000 years old. However, that date didn't sit right for many researchers.
