Re: When did human races split from one another?

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".
The classifications you list above were derived from a system that
depended upon one cultural group's perceptions of the relative
importance of certain physical characteristics of human beings.
That classification system was basically flawed.
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.
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: a French traveller
reported that the most-esteemed women in the group of young
women available to the Sultan for sexual expoitation were
said to be from a small part of the mountainous region east of
the Black Sea, i.e. Circassia in the Caucasus Mountains region.
Long after that French traveller was dead, the German-speaking
man who came up with the term "Caucasian" decided to give
his own "race" that name because it was descriptive of the
most beautiful people in the world, and he thought that it was
somehow more descriptive of fair-skinned people than
"Circassian", which was not a geographical term in his language.
The term "Caucasian" had nothing to do with human migration,
nothing to do with changes in human population genetics over time,
and would not include red-headed fair-skinned people from the
northwesternmost European islands, or most of the people
in Caucasus region. Because of these variations from observed
reality, it was adapted to "caucasoid" to include some people who
did not look like people from the Caucasus region but still excluded
most people in the Caucasus region.
"Caucasoid" has been used to describe Pacific islanders, so
your classification scheme is not even internally consistent.
It also has not mention of the other of the three original terms,
"Mongolian", later altered to "Mongoloid" or "Mongloid", which
in the list you gave, above, seems to overlap with "caucasoid"
in the "South East Asian & pacific islander" population, and
which is not-very-useful in the Europe-Asia boundary area.
I would ask you to consider the "mongoloid" epicanthic folds
of the eyes of former South African President and "negroid race"
hero Nelson Mandela, the "mongoloid" facial features of
Russian President and Europeran leader Vladimir Putin, and
the mixed "caucasoid" and "negroid" features of Advisor to the
people of Libya Muammar Ghaddaffi.
None of these people fit into your classification scheme.

Your questions cannot be answered, because they do not correlate
with the genetic variation or migration history of human beings.
The "races" that you listed do not exist.
