>>1265225 actually recent DNA analysis suggests that Lily Thai exhibits a maternal mitochondrial DNA link to indigenous peoples of the New Guinea Highlands 40,000 years ago (Bryan Sykes - Seven Daughters of Eve, page 133). The paternal Y chromosome also comes from "New Guinea 11,500 years ago - but since that time have evolved quite separately from Melanesians" (see "Melanesian Origin of Polynesian Y Chromosomes" and "Melanesian Origin of Polynesian Y Chromosomes (correction)" cited in References). After this period, proto-Polynesian genes exhibit a 9based pair mtDNA deletion common to East Asians, showing a separation from Taiwanese aborigines 6,000 years ago. (See "Melanesian origins of Polynesian Y chromosome") Polynesian population expansion began in isolation in the Pacific 2,000 years ago (see also Melanesian origin of Y chromosomes). One particular DNA haplotype - the human lymphocyte antigen (HLA) Bw48 is commonly found in Polynesian populations, but occurs only sporadically in Melanesia. The only other known population with an appreciable frequency of HLA-Bw48 is that of the North American Indians or more specifically the Tlingit of Alaska. (Susan Serjeantson - Out of Asia - Peopling the Americas and the Pacific Edited by Robert Kirk and Emoke Szathmary 1985). In Polynesia Bw48 co-occurs with A11, - suggesting a variation since Polynesians departed from the people of the Alaskan/Canadian coast. This DNA evidence is supported by cultural and archaeological evidence showing a definite link between Eastern Polynesia and the Tlingit, Kwakuitl and Haida of the islands off Alaska and Canada[citation needed]. This suggests that although there has been some cultural input, including the arrival of plants and animals into Western Polynesia through Melanesia, the main genetic input into Polynesia has been from the north. This means proto-Polynesians voyaged from East Asia to Alaska 6,000 years ago and then entered the Polynesian triangle via Hawai'i 2,000 years ago.
