[QUOTE]Originally posted by Djehuti: [QB] [QUOTE]Originally posted by Swenet: [qb] I think you're referring to the analysis undertaken by MacIver and Thomson. Note, though, that even of those "negroid" individuals, only a subset would cluster with most SSA groups. When you look at the criteria they used to identify negroid Egyptians, it covers not just Sub-Saharan Africans, but also northeast Africans and even Afalou and Taforalt (who we now know, have substantial Eurasian mtDNAs). One of the criteria they used was platyrrhiny. Look at the map below for an indication of how different populations relate in terms of this index: https://mathildasanthropologyblog.files.wordpress.com/2009/01/saharan-populations-compared1.png MacIver and Thompson started counting individuals as negroid already at 51%, while the Sub-Saharan population averages used here start at 57%. Most predynastic Egyptian populations average around 52%, while dynastic Egyptian populatons average lower, towards West Eurasians. Because of this, predynastic population averages are called negroid. But it's clear that most predynastic population averages are nowhere near the 57-60% range of the Sub-Saharan African population averages shown here. Lioness [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=009694;p=9#000442]recently posted this table from a German study, where various measurements of Egyptian mummies are listed[/URL]. As you can see, two of the four Egyptian mummies can be classified as negroid in terms of nasal index, but only one of these negroid individuals approaches the range of SSA population averages. The other three, one of which also has a 'negroid index', are far removed from SSA population averages: [IMG]https://i.imgbox.com/hNDlOZhM.png[/IMG][/qb][/QUOTE]Yeah, Thompson & MacIver's book [i]The Ancient Races of the Thebaid[/i] was exactly what I meant, though I'm embarassed to say that I wasn't aware until years later in this forum when the poster Rasol informed me there was a difference between "negroid" and "[true] negro". Thus many old scholars like Petrie, Gardiner, Griffith, and Mackay noted "negroid" features were not uncommon in Egyptians and some even outright called Egyptians "negroid" in appearance but not actually "negro". Although ironically enough these same scholars did note a very select few of the skeletal remains especially in Upper Egypt were of truly "negro" and thus foreigners. [QUOTE][qb]I have not looked into the possible genetic affiliations of prehistoric Central Saharans much, but the pre-Neolithic Round Head rock art in the Central Sahara and certain skeletal remains in the region support a presence of SSA groups there. I have posted about these skeletal remains in the past, but it was a long time ago. I don't remember the source, unfortunately.[/qb][/QUOTE]Well, like I said there were a number of cultures living in the central Sahara during the Holocene wet period, and the skeletal remains also display heterogeneity with some looking "negroid" (or negro) and others looking "Mediterranean" while others "Mechtoid". It varies from area to area. [QUOTE][qb]I have been working on the origins of those populations. I'm still gathering evidence to make sure I'm on point. I aint trying to go out like the Xyyman's "Niger Congo Natufians" that never materialized. Lol. [/qb][/QUOTE]I personally think these populations displaying so-called "caucasoid" morphology predate Afro-asiatic and Nilo-Sahran in the Great Lakes region and clues to who they may be genetically can be seen in the Hassan et al. paper I cited [URL=https://www.nature.com/articles/srep09996]here[/URL] with regards to the Maasai perhaps. By the way, I checked and realized it was Lioness who first posted the study in this forum 2 years ago [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=009232#000000]here[/URL].
