Ghost DNA is tracts of your DNA that contain traces of DNA from unknown ancestors. Some Ghost DNA occurs in sub-Saharan Africa where unknown DNA is about 60,000 years old: The Baka of Cameroon, a pygmy group. The Hadza of Tanzania, genetically distant from other people. The Sandawe of Tanzania, perhaps related to Bushmen. Ghost DNA occurs with all peoples—our ancestors were not careful who they mated with!
