The Sahara Desert was once a lush region during the African Humid Period, inhabited by human settlements. A genetic study of two 7,000-year-old mummies from Libya reveals a previously unknown 'ghost population' with distinct ancestry. This challenges existing views on African history and suggests limited genetic interaction between North and sub-Saharan Africa. The research proposes that agriculture and animal husbandry spread through cultural interaction rather than migration, highlighting the isolation of the Takarkori community due to diverse ecosystems.
