JCA's compilation of C3(xC3c) at Dienekes Hard to tell if C3 was present at the beginning of the Neolithic in North China.

I often find it interesting to review the earliest literature on a topic within the field of genetics in order to see how the consensus of the scientific community has taken shape. T. M. Karafet, S. L. Zegura, O. Posukh et al., "Ancestral Asian Source(s) of New World Y-Chromosome Founder Haplotypes," American Journal of Human Genetics 64:817-831, 1999 [I believe this study is the first one to have appeared in print with data regarding the prevalence of C-M130 (RPS4Y711), but the authors have cited Bergen et al. (1999) for the definition of the RPS4Y711 mutation: "We genotyped the M9 CG transversion (Underhill et al. 1997) and the CT transition at position 711 within the RPS4Y gene (Bergen et al., in press), using SSO hybridization."] Haplotype 1F (=C-RPS4Y711) 21/23 = 91.3% Oroqens (Northern Tungusic) 65/95 = 68.4% Siberian Evenks (Northern Tungusic) 26/41 = 63.4% Evens (Northern Tungusic) 49/81 = 60.5% Buryats (Mongolic) 78/148 = 52.7% Mongolians (Mongolic) 16/31 = 51.6% Australian Aboriginal People 6/12 = 50.0% Yukagirs 18/41 = 43.9% Manchurian Evenks (Northern Tungusic) 5/12 = 41.7% Tanana (Northern Athabaskan) 19/53 = 35.8% Indonesians (Malayo-Polynesian & several Papuan language families and isolates) 4/12 = 33.3% Koryaks (Chukotkan) 14/55 = 25.5% Melanesians (Malayo-Polynesian & several Papuan language families and isolates) 1/4 = 25% Chukchi (Chukotkan) 7/29 = 24.1% Altais (Turkic) 5/22 = 22.7% Kazakhs (Turkic) 6/28 = 21.4% Koreans 2/12 = 16.7% Kets (Yeniseian) 7/44 = 15.9% Cheyenne (Algonquian) 5/47 = 10.6% Papua New Guineans (several Papuan language families and isolates & Malayo-Polynesian) 2/20 = 10.0% Yakuts (Turkic) 2/26 = 7.7% South Chinese 2/26 = 7.7% Wayus (Maipurean) 3/44 = 6.8% Taiwanese 6/118 = 5.1% Japanese 2/60 = 3.3% Indians 1/30 = 3.3% Tibetans 1/56 = 1.8% Navajos (Southern Athabaskan) 2/122 = 1.6% Selkups (Southern Samoyedic) 0/4 Alaskan Eskimos (Eskimo-Aleut) 0/8 Komi (Permic) 0/22 Siberian Eskimos (Eskimo-Aleut) 0/27 Forest Nentsi (Northern Samoyedic) 0/30 Russians 0/32 British 0/32 Germans 0/36 Egyptians 0/38 African Pygmies 0/38 Southeast Asians 0/39 Italians 0/42 Greeks 0/43 East Africans 0/48 Gambians 0/52 Tundra Nentsi (Northern Samoyedic) 0/53 West Bantus 0/55 East Bantus 0/62 (Greenland?) Inuit (Eskimo-Aleut) 0/75 Khoisan A. W. Bergen, C.-Y. Wang, J. Tsai et al., "An Asian-Native American paternal lineage identified by RPS4Y resequencing and by microsatellite haplotyping," Annals of Human Genetics (1999), 63, 63-80 [This seems to have been the first study to describe M130 (RPS4Y711), but it has appeared in print after the aforementioned article by Karafet et al. (1999). Bergen et al. have stated, "One RPS4Y sequence variant, 711C>T, was polymorphic in Asian and Native American populations, but not in African and Caucasian population samples. ... The RPS4Y locus transposed to the Y chromosome early in primate evolution, is found between SRY and ZFY in Homo sapiens, and codes for a functional ribosomal protein (Fisher et al. 1990; Zinn et al. 1994; Bergen et al. 1998)."] C-RPS4Y711 21/90 = 23.3% Plains Native American 3/16 = 18.8% Korean 3/49 = 6.1% Taiwanese 0/20 Jamaican 0/21 Yakut Native Siberian 0/37 Southwest Desert Native American 0/43 Pueblo Native American 0/65 U.S. population sample 0/248 Finnish DE-DYS287 10/20 = 50.0% Jamaican 4/58 = 6.9% U.S. population sample 1/27 = 3.7% Pueblo Native American 3/94 = 3.2% Plains Native American 2/346 = 0.6% Finnish 0/37 Yakut Native Siberian 0/42 Korean 0/43 Southwest Desert Native American 0/66 Taiwanese |
