If some of the prominent dynastic Egyptians were 25% Eurasian would it bother you?

[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE]Originally posted by Ethan: [qb] Since Horn of Africa populations are more Eurasian than 25%, even excluding semitic-speaking populations like Amhara or Tigray people for instance(who are almost 50-50), it's almost impossible that most Ancient Egyptian populations were any less than 50% Eurasian. The study about Sudan (Dobon et al.) shows Beja people (speaking a very basal language in the Cushitic branch) are even more Eurasian than semitic-speaking populations of Eritrea-Ethiopia. Beja people being the closest Afroasiatic speaking population to Egyptian geographically (excluding Asian Bedouins and the atypical Siwa berberophones), they should represent a good-proxy for AEs if you don't like modern Copts.

[/b] The antiquity of the east African gene pool could be viewed not only from the perspective of the amount of genetic diversity endowed within it but also by signals of uni-modal distribution in their mitochondrial DNA (Hassan et al., unpublished) usually taken as an indication of populations that have passed through ‘‘recent’’ demographic expansion [33], although in this case, may in fact be considered a sign of extended shared history of in situ evolution where alleles are exchanged between neighboring demes [34].[/i] [IMG]http://oi58.tinypic.com/2w567ut.jpg[/IMG] [list] [*]Figure S1 Neighbor joining (NJ). NJ tree of the world populations based on MT-CO2 sequences. The evolutionary relationship of 171 sequences and evolutionary history was inferred using the Neighbor-Joining method. The optimal tree with the sum of branch length = 0.20401570 is shown. The evolutionary distances were computed using the Maximum Composite Likelihood method and are in the units of the number of base substitutions per site. Codon positions included were 1st+2nd+3rd+Noncoding. All positions containing gaps and missing data were eliminated from the dataset. There were a total of 543 positions in the final dataset. Phylogenetic analyses were conducted in MEGA4. Red dots: east Africa, Blue: Africa, Green: Asia, Yellow: Australia, Pink: Europe and gray: America.
