Migration back to Africa took place during the Paleolithic
The Palaeogenomics study conducted by the Human Evolutionary Biology group of the Faculty of Science and Technology, led by Concepción de la Rua, in collaboration with researchers in Sweden, the Netherlands and Romania, has made it possible to retrieve the complete sequence of the mitogenome of the Pestera Muierii woman(PM1)using two teeth. This mitochondrial genome corresponds to the now disappeared U6 basal lineage, and it is from this lineage that the U6 lineages, now existing mainly in the populations of the north of Africa, descend from.
