[QUOTE]Originally posted by rasol: [QB] [QUOTE]Originally posted by Comworks: [qb] But wouldn't that ultimately mean that all World lineages are directly African. In human genetics, Haplogroup F (defining mutations M89, P14, and M213) is a Y-chromosome haplogroup. This haplogroup and its subclades contain more than 90% of the world's extant male population, including almost everyone outside of Africa. Haplogroup F is an ancestral haplogroup to Y-chromosome haplogroups G (M201), H (M52), I (M170), J (12f2.1), and K (M9) along with K's descendant haplogroups (L, M, N, O, P, Q, and R) [/qb][/QUOTE]That is the very meaning of Out of Africa. [i]Small groups of settlers expanding outward from Africa are the most likely progenitors of the modern human population [b]worldwide[/b]. While still a student at Yale Medical School, Tishkoff developed a novel way to analyze DNA from living people's blood. Then, by determining the frequency of mutations in DNA from various populations, she was able to conclude that African lineages are the oldest on Earth and that at some relatively -recent- time in the past, a -small group- of people migrated out of East Africa and populated the rest of the world. Several populations thought to have originated in northeastern Africa are ancient, dating back 90,000 years[/i] http://www.popsci.com/popsci/science/b6b80b4511b84010vgnvcm1000004eecbccdrcrd/11.html [/QB][/QUOTE]
