Description and sources
The eurasian Y-chromosomal haplogroup K is consistent with the scenario that the coastal southern route migration from Africa carried the ancestral Eurasian lineages first to the Indian subcontinent and probably it originated there[1] about 47,000 years ago.[2]
Haplogroup L is probably of Middle-Eastern origin.[3] The dispersal of haplogroup T also points within the Near East and from the Near East to sub-Saharan Africa mainly.[4]
An initial rapid diversification process of K2 (M526) likely occurred in Southeast Asia.[5] K2c was observed in Bali, K2d in Java and MS (or K2b1) diversifies in Maritime Southeast Asia and is related to the settlement of Oceania.[5]
NO diversified into the Far East, and while O spread throughout East Asia and Southeast Asia, N expanded to the north and through southern Siberia reached into northeastern Europe.[6]
The greatest diversification of P was in Southeast Asia and its main clade P1 was found in human remains from North Asia, which occurred before diversifying into Q and R;[7] while P2 was found in the Philippines.[8]
Q is considered to have arosed in Central Asia,[9] like R1 and R2.[3]
Subclades of Q are related to the settlement of the Americas. The Amerindians are characterized by the presence of Q-M3 and Q-Z780, while the Eskimos have Q-YP1500.[10]
It has been suggested that R1a (M420) would have originated in the vicinity of Iran, While R1a-M17 would have an European origin.[11] R1b would have originated in the Near East,[12] expanding during the Holocene into Europe[13] and sub-Saharan Africa.[14]
