Does everyone agree that we evolved from Africa?

"True" Black Africans appear as a recent adaptive radiation in the above
dendrograms, apparently branching off from an ancestral Pygmy population-a
line of ancestry also indicated by osteological data (Coon 1962:651-656;
Watson et al. 1996). This radiation seems to have occurred somewhere in
West Africa.
Before the Bantu expansion about 3,000 years ago, true Black
Africans were absent from the continent's central, eastern, and southern
regions (Cavalli-Sforza 1986:361-362; Oliver 1966). They were also absent
from the middle Nile until about 4,000 years ago, at which time they begin
to appear in paintings from Pharaonic Egypt and in skeletal remains from
Nubia (Junker 1921).
