[QUOTE]Originally posted by Truthcentric: [QB] [QUOTE]Originally posted by Hersi_Yusuf: [qb]I know races don't exist but I was wondering if all native africans are more related to each other then any other group of people shouldn't that be consider a race or a independent population? I mean not on a skin color or phenotype level but on a genetic level, seeing that most africans are long limbed, dark skinned people and share common ancestry really the only people who don't fit that are the so called "white" berbers but they still have the "black" hap group E from what i studied. So can you guys clear that up for me because what I've gathered through studies is that africans are a diverse people ranging all phenotypes and a wide variety of skin tones but they are still related very closey and I think we should still use the concept of race in a new way not in skin color but in gentics.[/qb][/QUOTE]The fact that you can't include all Africans into a single race without including the rest of humanity (because all human genetic variation is nested in African variation) would suggest against this. Human DNA Sequences: More Variation and Less Race Jeffrey C. Long,1* Jie Li,1 and Meghan E. Healy2 1Department of Human Genetics, University of Michigan, Ann Arbor, MI 48109-5618 2Department of Anthropology, University of New Mexico, Albuquerque, NM 87131 KEY WORDS race; DNA sequence; short tandem repeat; diversity; hierachical models [QUOTE] The pattern of DNA diversity is one of nested subsets, such that the diversity in non-Sub-Saharan African populations is essentially a subset of the diversity found in Sub-Saharan African populations. The actual pattern of DNA diversity creates some unsettling problems for using race as meaningful genetic categories. For example, the pattern of DNA diversity implies that some populations belong to more than one race (e.g., Europeans), whereas other populations do not belong to any race at all (e.g., Sub-Saharan Africans). As Frank Livingstone noted long ago, the Linnean classification system cannot accommodate this pattern because within the system a population cannot belong to more than one named group within a taxonomic level. ... A classification that takes into account evolutionary relationships and the nested pattern of diversity would require that Sub-Saharan Africans are not a race because the most exclusive group that includes all Sub- Saharan African populations also includes every non- Sub-Saharan African population (Figs. 2B and 4B). Moreover, the Out-of-Africa branch would place all Eurasians in the same race, but this would necessitate placing Europeans and Asians in sub-races.[/QUOTE] [/QB][/QUOTE]
