Two 7,000-year-old mummified women discovered with strange DNA profiles

Two 7,000-year-old mummified women discovered in Libya have revealed a previously unknown North African lineage, challenging the understanding of the Green Sahara's genetic history. Genetic tests show these women had no detectable roots in sub-Saharan Africa and only a small trace of Neanderthal ancestry, suggesting limited gene flow between northern and southern populations. The findings indicate that herding practices spread through cultural diffusion rather than large migrations, offering insights into the complex history of human movement and adaptation in North Africa.
