    In this study we have focused our attention to the human mitochondrial DNA haplogroup L3 encompassing not only many sub-Saharan Africans but also all ancient non-African lineages. The age estimate of this specific clade therefore provided us upper time limit for the dispersal of modern humans out of Africa. We have analyzed 369 complete African L3 genomes and placed the maximum at 70 ka. Therefore we have ruled out a successful exit of the anatomically modern humans before 74 ka, the date of the Toba volcanic super-eruption in Sumatra. The later time of the spread of modern humans can be linked rather to improved climatic conditions in Africa than to behavioral changes that appeared earlier. Furthermore, we have concluded that another migrations emanated from Eastern to Central Africa between 60 - 35 ka and again after last glacial maximum at 20 ka. However, the largest demographic growth seen in our L3 dataset is 3 - 4 ka in Central Africa corresponding to the expansion of the Bantu pastoralists.
