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?

Studies of mitochodrial DNA show when various human communities split
from others. This cannot be used to justify "races" as it is basically
a meaningless category and am surprised to see it still i existence in
the 12st century.


READ it back first!!!!! I mean 21st century!!!



A mitochondrion is the power house of all living cells. It has a unique
DNA that is in no way related to the host organism. In other words
mitochodria reproduce themsleves by division and exist in symbiosis
with humans. Mitochondria are passed from mother to child during the
development of the foetus and undergo no re-combination of genetic
material as they reproduce asexually.
The implications of this has been that it enables different human
population to be mapped in terms of their chronological differentiation
providing that the natural mutation rate is constant.
