Haplogroup M-P256

Haplogroup M, AKA M-P256 and Haplogroup K2b1b (previously K2b1d) is a Y-chromosome DNA haplogroup. M-P256 is a descendant haplogroup of Haplogroup K2b1, and is believed to have first appeared between 32,000 and 47,000 years ago.

M-P256 is the most frequently occurring Y-chromosome haplogroup in West Papua and western Papua New Guinea. In addition, M-P256 is also found in neighboring parts of Melanesia, Indonesia and indigenous Australians.

This phylogenetic tree of haplogroup subclades is based primarily on the trees published by YCC in 2008 and ISOGG in 2016.

The paragroup M-P256* is found at a low frequency in New Guinea (6.3%) and Flores (2.5%).

This group is found frequently in New Guinea and Melanesia, with a moderate distribution in neighboring parts of Indonesia, Micronesia, and Polynesia.

An extreme geographical outlier was apparently identified in a 2012 study, which reported a Hazara individual from Mazar-e Sharif, Afghanistan, with M1 (among a sample of 60 males from the mentioned area). The Hazara individual carried the SNP M186 (which is believed to be equivalent to M4).

M1a (M-P34) is the most frequently occurring Y-chromosome DNA haplogroup in Western New Guinea. It is also found with moderate frequency in neighboring parts of Indonesia (Maluku, Nusa Tenggara) and throughout Papua New Guinea, including offshore islands.

M1b M-P87(xM104/P22) has been found in approximately 18% (20/109) of a pool of samples from New Ireland, approximately 12% (5/43) of a sample of Lavongai from New Hanover, approximately 5% (19/395) of a pool of samples from New Britain (and, in particular, in about 24% (15/63) of Baining from East New Britain), in addition to one Saposa individual from northern Bougainville, and another individual from the north coast of Papua New Guinea.
