Sorry fo this Nazi-like thread title but I was just looking at this chart again>
quote:Originally posted by Truthcentric: I have just downloaded this new limb proportion study onto my laptop at UCSD. If anyone's interested in taking a look, PM me your e-mail so I can send it to you.
To give you a preview of the findings, here's a dendrogram showing similarities in limb proportions between the populations measured:
Population Affinities of the Jebel Sahaba Skeletal Sample (Holliday 2013)
I printed out this chart and measured. It looks like Nubian limb ratios are about 2.5 times more distant to West Africans then they are to Germans and over 3 times more distant to East Africans then they are to Germans I haven't seen the whole article but since Nubians are East Africans they must be being distinguished here from other East Africans and/or are ancient Nubians. (Pygmies are a special case because their short height adds a possible Bergmann's Rule factor)

What was the climate like in that region during (pre and post) that time and date?

Although the main question is do you know how to read it, what good is the dendrogram without the context of the text in which it was given and the data behind it?
Eg., what does the author say about the Circumpolars in regard to their dimensions? Is it as expected or ... ? Are they more or less cold adapted than others in the chart's two major clusters?
Still waiting for you to explain to us how to read that dendrogram.
Please direct your team to produce that if the casket not dropped.

The way to determine the distance bewteen two populations on the above dendogram is to start at the name of the first populaltion. Then you follow the line path eminating from that name it like a mouse in a maze to the second popualation. You can move in any direction along the path, up, down, backwards or forwards, whatever is the shortest distance from one population to the next. Since the scale of this chart is horizontal you only record the distances of the horizontal movements. When you put these horizontal segments together and measure them in total, that is the distance bewteen two populations

The Lower Nubian Epipaleolithic site of Jebel Sahaba (Sudan) was discovered in 1962. From 1962 to 1966, a total of 58 intentionally buried skeletons were uncovered at the site. Diagnostic microliths indicative of the Qadan industry as well as the site's geology suggest an age of 14–12 ka for these burials. In this study, the body proportions of the Jebel Sahaba sample are compared with those of a large (max N = 731) sample of recent human skeletons from Europe, Africa and circumpolar North America, as well as to terminal Pleistocene ‘Iberomaurusian’ skeletons from the Algerian sites of Afalou-Bou-Rhummel and the later Capsian-associated Ain Dokhara specimen, as well as Natufian skeletons from the southern Levantine site of El Wad.
* East Africa vs Tigara or * Pygmy vs EuroAmerican ?
By your method is Jebel Sahaba closer to * East Africa or * West Africa?
What is the meaning of branches on the same limb?
What is being measured as the distance between populations?

Yes, I know it shows limb ratios, but explain its relevance to what I asked cass.
