    This study shows that the time after Last Glacial Maximum was the most significant period in the formation of the extant genetic diverzity of Southern Arabia. Several demographical expansions can be detected within the internal diversification of, in Arabia, widespread mitochondrial haplogroup R0a. We present resolved phylogenetic tree of 89 whole mitochondrial genomes (71 being newly presented here) belonging to R0a. Interestingly, two geographically specific lineages (R0a1a1a and R0a2f1) were identified in non–Arabic speaking peoples such as the Soqotri and Mahri. They live in the same part of the Southern Arabia where a past population refugium was recently identified by independent archaeological studies. Age estimates of the most recent common ancestor of these lineages corresponds with the earliest archaeological evidence for seafaring activity of the Arabian peninsula in the sixth millennium BC.
