I'm sure the two million 'full blooded' Native Americans registered in the
2000 census will be delighted to learn they don't exist. Actual anthropological
evidence contradicts your notion that the last millenia or so of influxes have
effectively changed the character of the Egyptian population. BTW there was
plenty of immigration from the east as well as the south in AE. They were always
complaining about the 'Wretched Asiatics'.

Again of course the AEs are 'Africans'! But that does NOT make them identical
physically or culturally to all other peoples in Africa. BTW my understanding
is the latest thinking is the ancesters of the AE migrated into the Nile Valley
from the Sahara as it dried - not up the Nile from the south.
