Where does Cruciani say this ?
I have cruciani saying that E came from the Nile delta as well as the upper Nile ( egypt and ethiopia)
On the other hand, when only E-V13
chromosomes from western Asia are considered, the resulting network (fig. 4B) does not show such a star-like shape, and a much earlier TMRCA of 11.5 ky (95% CI 6.8–17.0; fig. 1) is obtained. These results open the possibility of recognizing time windows for 1) population movements from
the E-M78 homeland in northeastern Africa to Eurasia and
2) population movements from western Asia into Europe
and later within Europe.
The low E-V13 frequency (0.9%) and microsatellite
variance (0.13) in northern Africa do not support an antiquity greater than in western Asia. Thus, the most parsimonious and plausible scenario is that E-V13 originated in
western Asia about 11 ky ago, and its presence in northern
Africa is the result of a more recent introgression.
Under this hypothesis, E-V13 chromosomes sampled in western Asia and their coalescence estimate detect a likely Paleolithic exit out of Africa of E-M78 chromosomes devoid
of the V13 mutation, which later occurred somewhere in
the Near East/Anatolia.
