Scientists have long studied the origin of all humankind and it seems like they may be closer to an answer…
Yep, a study published Monday states that our ancestors thrived for 70,000 years in the Greater Zambezi River Basin, which includes the northern part of Botswana. Eventually, scientists believe, climate change forced them to migrate out of Africa and scatter across the globe.
How’d they come to such a specific conclusion? Fossils, which led them to DNA evidence, which pointed to southern Africa.
“It has been clear for some time that anatomically modern humans appeared in Africa roughly 200,000 years ago. What has been long debated is the exact location of this emergence and subsequent dispersal of our earliest ancestors,” said Vanessa Hayes, lead study author at the Garvan Institute of Medical Research and the University of Sydney. “We’ve been able to pinpoint what we believe is our human homeland.”
It’s complicated, but basically they collected DNA samples from living communities in the region and cross checked it with the other DNA. Phew.
Science is wild, right?! -Taylor
