Out of Arabia : the settlement of island Soqotra as revealed by mitochodrial and Y chromosome genetic diversity

Popis výsledku v původním jazyce

The island of Soqotra lies not far from the proposed southern migration route of anatomically modern humans out of Africa 60 thousand years ago (kya). However, nothing is known about the timing and origin of the first Soqotri settlers. The oldest historical visitors to the island in the 15th century reported only the presence of an ancient population. We found little African influence among the indigenous people of the island. The island population likely experienced several founder effects but links tothe Arabian Peninsula or southwestern Asia are evident. The Soqotri population shows evidence of long-term isolation and autochthonous evolution of mitochondrial haplogroup R0a. We identified two high-frequency founder lineages that have not been detected in any other populations and were classified as a new R0a1a1 subclade. Recent expansion of the novel lineages is consistent with a Holocene settlement of the island 6 kya.
