But you cannot establish that all Eurasian ancestry in Lower Egypt is recent, post-Hyksos.<quoted text>
The funny thing about bubble head Barros is, he doesn't understand that there is no PHYSICAL evidence. So he/ she / it rants about genetic intrusion. Yes, Lower Egyptians have a relatively high dosage of foreign ancestry, as is seen in the gene pool, however, these are from recent introductions, in the last couple of thousands of years. And on top of this, Eurasians /Asiatics (Arabs) were cold adapted and still are cold adapted.
What we can say, however, is that in the Holocene, humans from southwest Asia do not exhibit tropically adapted body shape (Crognier 1981; Eveleth and Tanner 1976; Schreider 1975).... "

Nor does the European:
In fact, in terms of body shape, the European and the Inuit samples tend to be cold-adapted and tend to be separated in multivariate space from the more tropically adapted Africans, especially those groups from south of the Sahara.

Body proportions of circumpolar peoples as evidenced from skeletal data: Ipiutak and Tigara (Point Hope) versus Kodiak Island Inuit.
The rest of your post is commonplace information about body proportions relevant to climate.
Genetics are what definitively shows ancestry.
Certainly you Afronazis by now have learned (from us in here at least) that cranial and limb proportions are not reliable indicators of ancestry. They changed over time, they evolved convergently... they don't answer our questions.
Certainly someone has analyzed the DNA of predynastic Lower Egypt. Doesn't have to be 30,000 years old, since you Afronazi cultists are claiming there were no Eurasians there until the Hyksos...
