[QUOTE]Originally posted by Whatbox: [QB] @liness: = more than just adaptation = genetic affinity with and migration involving folks from climate where such adaptation comes about. [QUOTE]Originally posted by Near: [qb] Are tropical body plans more than just height? [/qb][/QUOTE]This explains your first question :D (answered below). Let me explain this citation in my first post. Follow the bolded and this should answer your question easy. In the more Tropically adapted: [i]"The values for the brachial and crural indices show that the [b]distal segments of each limb are longer relative to the proximal segments[/b] than in many “African” populations (data from Aiello and Dean, 1990). This pattern is supported by Figure 7 (a plot of population mean femoral and tibial lengths; data from Ruff, 1994), which indicates that the Egyptians generally have tropical body plans."[/i] - Zakrzewski et. al. 2003 If tropical body plans were height this would be dumb, it wouldn't be able to tell anyone anything at all. There are tell groups of people on every continent (Swedes of Sweden and certain Sudanese groups i think the Shilluks being some of the tallest in the world .. and Kenyan Maasai are pretty tall) and most if not all pygmy (abnormally short) populations that i know of live in more tropical climates than whites: they are found in inner Africa and Southern Asia. By the way, Badarians here are on the lower end of the Egyptian tropically adapted scale: [QUOTE][i]"Of the Egyptian samples, only the [b]Badarian[/b] and Early Dynastic period populations [b]have shorter tibiae than predicted from femoral length.[/b] Despite these differences, all samples lie relatively clustered together as compared to the other populations."[/i][/QUOTE]Do you know what a Tibia or Femur bone is? The Tibia is your major lower leg bone another word for shin, and the femur is your thigh bone. The more tropically adapted you are the longer your distal (distant) limbs relative to your proximal (close) in [b]*intra-limb*[/b] (limb part to limb part) indices or measurements. [b]Limb-trunk[/b] (limb to trunk) measurements are supposedly more accurate though as per a newer 2007 study involving ancient Egyptian - black and white American comparisons done by Raxter. Does this clear it up for you? [QUOTE]Originally posted by Near: [qb] Wait, so the body plans are not the result of diet?[/qb][/QUOTE]No. She does mention though, their stunted growth. It isn't even apparent from the video however if this at all affected their measurements in terms of tropical adaptation as opposed to just stunting their growth. If it did affect how tropical they were, stunted [b]outlier[/b] people as an example of his least tropically adapted ancient Egyptians (who all still mostly cluster together) is not evidence i would use were i him. Makes him seem desperate. [QUOTE][qb] And according to the study, they were extremely tropically adapted (more so than other African populations). [/qb][/QUOTE]Ancient Egyptians in general yes. [QUOTE][qb] And the MK "Nubian" sample, Zakrzewski states all samples lie clustered together as compared to other populations including "Nubians" right? [/qb][/QUOTE]On the vid he shows a part where she says she's holding them as a potential out group of outlier because of their apparent admixture with Nubians. Really though, as we know here there were plenty of Dynasties and regions with influence from folks people today lazily call "Nubians". The original ancient "Egyptian" term comes from a city going by the name Nub.t or "Golden" and there i think was a vocational title along the same lines (gold miner). I'm [b]not sure whether or not she actually did exclude or include the sample[/b] and frankly you'll have to read the study yourself, i'm more interested in the fairly new field genetics now if anything (the picture is still clearing up, it's current, fresh, more intriguing for me) and less in such a video. By the way, just as you edited you post with more questions i'd before you finished editing edited mine in terms of my commentary to clarify. Someimtes i'm incoherent when i write fast and have to recheck my text, hope i didn't cause any confusion. [/QB][/QUOTE]
