[QUOTE]Originally posted by Troll Patrol # Ish Gebor: [QB] [QUOTE]Originally posted by Dead: [qb] Theoretically Melanesians should be 86+ like other Old World populations at tropical/equatorial latitude. Instead they are 84.8. This has to do with the recent large-scale mixture of the natives islanders with Austronesians who settled across Melanesia from Taiwan and southern China. Like Melanesians, African-Americans are not tropically adapted. AA's are 85.1. This is because the average African-American has recent white ancestry. West African and East Africans means are both 86+ [the "South African Black" sample mean in the above table is 86.2-3]. None of the data supports your clustering attempt. You are trying to pool all these populations together, but it doesn't work. What West & East Sub-Saharan Africans match is the Lower and Upper Nubian series, not Egyptian. The data is there for anyone to read. The quote from Bleuze et al., 2014 who point out: ancient Egyptian "crural indices [are] more similar to Southern Europeans" is directly citing Raxter (2011). They aren't talking about the late period series. I'm not claiming they pool with Southern Europeans, but that they are intermediate/warm-adapted/subtropical, but fall closer to Mediterranean's, when compared to populations at hot tropical latitude like Sub-Saharan Africans (the Melanesians though aren't a good example for the reason I pointed to above). And you can combine Lower and Upper Egyptians to produce an overall mean. It comes out still below 85.

[IMG]http://www.nature.com/nature/journal/v507/n7491/images/nature12960-f2.jpg[/IMG] The SNPs around the two diagnostic variants (red arrows) in these two genes were analysed. The resulting haplotype comprises neighbouring SNPs that are also absent in modern Europeans (CEU) (n = 112) but present in Yorubans (YRI) (n = 113). This pattern confirms that the La Braña 1 sample is older than the positive-selection event in these regions. Blue, ancestral; red, derived.

Furthermore, three fixatives were tested with each of the rehydration fluids. Meniscus (fibrocartilage), skin, and a placenta were used for this study. The rehydration and fixation procedures were uniform for all methods. Materials and methods In 1997, the German Institute for Archaeology headed an excavation of the tombs of the nobles in Thebes-West, Upper Egypt. At this time, three types of tissues were sampled from different mummies: meniscus (fibrocartilage), skin, and placenta. Archaeological findings suggest that the mummies dated from the New Kingdom (approxi- mately 1550-1080 BC). Skin Skin sections showed particularly good tissue preservation, although cellular outlines were never distinct. Although much of the epidermis had already separated from the dermis, the remaining epidermis often was preserved well (Fig. 1). [b]The basal epithelial cells were packed with melanin as expected for specimens of Negroid origin. [/b] In the dermis, the hair follicles, hair, and sebaceous and sweat glands were readily apparent (Fig. 2). Blood vessels, but no red blood cells, and small peripheral nerves were identified unambiguously (Fig. 3). The subcutaneous layer showed loose connective tissue fibers attached to the dermis, and fat cell remnants were observed. To evaluate the influence of postmortum tissue decay by micro-organisms, the samples were tested for the presence of fungi using silver staining[/QUOTE].
