Modern human origin traced to northern Botswana

The video discusses the origin of modern humans from the region south of the Zambezi River, spanning parts of Botswana, Namibia, and Zimbabwe. Scientists collected DNA samples from local communities to trace the LO lineage, linked to early human populations. The study connects these populations to the Makkadakkadi Okavango paleo wetland, which once hosted Africa's largest lake system. This ecosystem supported human life for about 70,000 years before climate changes prompted migration.
