Does anyone know any up to date estimates on when humans split into
separate races? Obviously all humans started out as one race, so at
what dates in history did the human population split into the major
geographic races such as negroids, caucasoids, South East Asian &
pacific islander, north east asian? What was the chronological
sequence in which those major races split from one another and what
were the dates?

lauriecurtispj@xxxxxxxxxxx:

The classifications of human beings that you listed above are not
"separate races".
Also, they do not describe "major geographic races".


Well put it this way: When did the georgraphic areas corresponding to
what are commonly seen as the major races get settled, and what was the
chonological sequence of splitting? When did modern humans first
appear in sub-Saharan Africa? Did we then leave Africa to colonize a
caucasoid region (middle east/europe)? How long ago? Did a separate
wave of humans leave Africa to colonize Southeast Asia and the Pacific
Islands? If so, how long ago? When did the first modern humans colonize
North East Asia and were they descended from the caucasian region of
the world or their Southeast Asian neigbors?


The first classification you list, "negroid", is based upon
the size of melanin granules in the skin. There is no special genetic
relationship between populations with large melanin granules, who
are found in South East Asia, among Pacific islanders, within
populations otherwise described as "caucasoid", and on the
African continent.

negroid is based on black or sub-Saharan ancestry. Dark skin is just a
common negroid trait, but there are dark-skinned non-negroids (i.e.
Southeast Asians & Pacific Islanders)


The second term you listed, "caucasoid", is based upon
the sexual preferences of castrated harem managers in Istanbul
during the latter history of the Ottoman Empire:

But it's been confirmed by genetic cluster studies. People from the
middle east, europe, South asia, and to some extent ethiopia all form a
genetic cluster which corresponds to the caucasoid race of ancient
anthroplogy It makes sense that people who live close to one another
will form certain genetic profile that distinguishes them from people
who live further away.
