A recent study in Nature reveals insights into the ancient Green Sahara people, who inhabited the region during the North African Humid Period, approximately 14,500 to 5,000 years ago. DNA analysis from remains found in the Takarkori rock shelter indicates that these people formed a unique, isolated group with North African ancestry, contradicting prior theories of migration from sub-Saharan Africa. Their genetic profile shows less Neanderthal DNA and a stable population size of around 1,000, suggesting they transitioned from hunter-gatherers to herders without significant outside influence.
