[QUOTE]Originally posted by zarahan- aka Enrique Cardova: [QB] [b]So basically Lower Egyptians came from the East and adapted to the hot climate of Egypt, while the Upper Egyptians are group in the middle of the two. In other words "Super Negroid" Egyptians has been debunked, with these new methods. [/b] Don't celebrate too soon Ace. Raxter is a solid researcher, but there are some flaws in her presentation. In fact, your use of her bi-iliac ranges will not do much for your much touted "wandering Caucasoids" project. [b]In earlier studies (one of which Raxter herself did) US Blacks as a tropial people were used as a stand-in to estimate height of Ancient Egyptians. In those studies Black AMericans were found to cluster closer to Ancient Egyotians than EUropeans. That finding is not changed at all by Raxter's 2011 study. In fact, the new study AGAIN confirms that tropical peoples have similar limb proportions- hence Egyptians and Nubians cluster thereby. And the clustering of Black Americans has not changed one bit.[/b] Sorry. Bi-iliac ranges are correlated with many things including thermoregulation and locomotion. They are also correlated with stature, and with a shift to agriculture. Hence an "intermediate" bi-iliac range could be easily due to any of the above, including a shift from the mixed economy pre-dynastics, to the more agricultural early dynastic/dynastic types. Such ranges change slowly hence there would not be dramatic jumps in the data over time. Thus "incoming Caucasoids" are not needed to explain "intermediate" bi-iliac ranges lest anyone be tempted to make that interpretation. [b]QUOTES:[/b] [i] "Furthermore bi-iliac breadth appears to change slowly over time, likely due to multiple factors (thermoregulation, obstetrics, locomotion) influencing its shape (Ruff 1994; Auerback 2007).." "Generally narrower body breaths of the foragers contrast markedy with the wider-bodied agriculturalists. Although bi-iliac breadth has been argued to be stable over long periods of time (Auerbach, 2007), this shift in mean body breath may be indicative of changes correlated with subsistence economy." "Any use of the bi-iliac breath/stature body mass estimations would inherently reflect changes in stature.." [/i] -- Pihasi & Stock. 2011.
