Mitochondrial Haplogroup Q
Mitochondrial haplogroup Q
Mitochondrial Haplogroup Q is one of the lineages found almost exclusively in Oceanic and aboriginal Southeast Asian populations. It is believed to have originated in Island Southeast Asia or in the New Guinea region approximately 30-50,000 years ago. Subtypes Q1 and Q2 are widespread in Melanesia, particularly in the Bismarck Archipelago of New Guinea, in the Solomon Islands, Vanuatu and New Caledonia. The subtype Q1 was carried across the Pacific, most likely as part of the Lapita cultural expansion some 3,000 years ago and is found at low frequency in Fiji, Tonga, Samoa and as far east as the Cook Islands and Tahiti. It may be found in very low frequency in other East Polynesian locations.
