Ancient DNA Reveals Isolated Saharan Population 7,000 Years Ago
2025-04-11
A new genetic analysis sheds light on the genetic makeup of humans living in the Sahara's green oasis 7,000 years ago. Researchers sequenced ancient DNA from two women buried at the Takarkori rock shelter in Libya, finding their closest genetic relatives were 15,000-year-old foragers from Morocco. This suggests a long-standing, stable population in North Africa before and during the Saharan humid period. This lineage diverged from those leaving Africa over 50,000 years ago and remained largely isolated for millennia, with only minor gene flow from the Levant, including Neanderthal DNA. The study suggests pastoralism spread through cultural exchange, not large-scale migration.
