A New Study Has Changed the Birthplace of Humanity

New genetic research further shows that humans didn’t derive from a single location. Instead, it likely arose from multiple areas in Africa.
The rise of different population groups may have happened during different time periods.
Africa remains the focal point of the search for the earliest human existence, even if it may not have a single point of origin.
Stop looking for a single pinpoint location for the start of human evolution. A new study rooted in genetic modeling from experts across the world says that there is substantial evidence that we came from a whole bunch of places. Published on May 17 in Nature, the study claims to disprove the the idea of just one location serving as the birthplace of humanity.

“Decades of study of human genome variation have suggested a predominantly tree-like model of recent population divergence from a single ancestral population in Africa,” the study says. “It has been difficult to reconcile this finding with the fossil and archaeological records of human occupation across the vast African continent.”

To reach their conclusion, the researchers investigated the genomes of nearly 300 people across a variety of ancestral backgrounds and—even going back a million years—still weren’t able to lock in on just one distinct population set. Instead, their findings suggested that there must be at least two populations, which they dub Stem1 and Stem2.

“We cannot rule out the possibility that more complex models involving additional stems, more complex population structure, or hybrid models including both weak structure and archaic hominin admixture, may better explain the data,” the study says.
