was developed the modern inhabitants of the shores of
the Mediterranean in Europe, Asia, and Africa and, by mingling with the
primitive Negroes, the ancient Egyptians and modern Negroid races of
Africa.
As we near historic times the migrations of men became more frequent from
Asia and from Europe, and in Africa came movements and minglings which
give to the whole of Africa a distinct mulatto character. The primitive
Negro stock was "mulatto" in the sense of being not widely differentiated
from the dark, original Australoid stock. As the earlier yellow Negro
developed in the African tropics to the bigger, blacker type, he was
continually mingling his blood with similar types developed in temperate
climes to sallower color and straighter hair.
We find therefore, in Africa to-day, every degree of development in
Negroid stocks and every degree of intermingling of these developments,
both among African peoples and between Africans, Europeans, and Asiatics.
The mistake is continually made of considering these types as transitions
between absolute Caucasians and absolute Negroes. No such absolute type
ever existed on either side. Both were slowly differentiated from a common
ancestry and continually remingled their blood while the differentiating
was progressing. From prehistoric times down to to-day Africa is, in this
sense, primarily the land of the mulatto. So, too, was earlier Europe and
Asia; only in these countries the mulatto was early bleached by the
climate, while in Africa he was darkened.
It is not easy to summarize the history of these dark African peoples,
because so little is known and so much is still in dispute. Yet, by
avoiding the real controversies and being unafraid of mere questions of
definition, we may trace a great human movement with considerable
definiteness.
Three main Negro types early made their appearance: the lighter and
smaller primitive stock; the larger forest Negro in the center and on the
west coast, and the tall, black Nilotic Negro in the eastern Sudan. In the
earliest times we find the Negroes in the valley of the Nile, pressing
downward from the interior. Here they mingled with Semitic types, and
after a lapse of millenniums there arose from this mingling the culture of
Ethiopia and Egypt, probably the first of higher human cultures.
To the west of the Nile the Negroes expanded straight across the continent
to the Atlantic. Centers of higher culture appeared very early along the
