It is known that there had to be some migrations back into Africa due to the genetics recovered from northern africa prior to the islam.
Now there is even more evidence showing this departures and returns.
This so-called Mota genome is the first sequenced from African skeletal remains, which are less hospitable to DNA molecules due to the warm climate. “Africa is going to be a difficult place for having ancient genomes—especially high quality genomes,” Carles LaLueza-Fox, a paleogeneticist at the Institute of Evolutionary Biology in Barcelona, Spain, who was not involved with the study, told Nature.
An international team published the ancient genome last week (October 8) in Science.The researchers compared Mota’s DNA sequence with modern African genomes and ancient Eurasian DNA, finding evidence to suggest that the man’s genetic material most closely aligns with DNA from modern Ethiopian highlanders of the Ari tribe. Mota and modern Ari genomes bear marks of ancestors likely moved from the Near East into Europe about 9,000 years ago.
“By having these high coverage genomes, we can start seeing a lot of information about what happened,” study coauthor Ron Pinhasi from University College Dublin, Ireland, told New Scientist. “It is the right direction but we need more.”
