Two 7,000-year-old mummies from the Takarkori rock shelter in the Sahara have been found to be from a group with a previously unknown ancestry.
Pretty interesting stuff given how hard it is to preserve genetic material in the desert arid environment. While the DNA has been linked to another set of remains it is very interesting that the lineage seems to have died out without any known explanation.
The majority of Takarkori individuals’ ancestry stems from a previously unknown North African genetic lineage that diverged from sub-Saharan African lineages around the same time as present-day humans outside Africa and remained isolated throughout most of its existence
