good god amighty!
as far as NOI mythology - what does that have to do with the information
in the interview ... the interview that you didn't even read and yet are all
up in the discussion. what are you afraid of?
the NOI teaches that white people were grafted out of black people .. you
know grafting, the scientific process that white folks are utilizing today in
their labs? if you think that is mythology what is your explanation for how
white people came to be on the planet?
let's hear it.
I was originally gonna stay out of this thread, but as a student and lover of
evolutionary biology, I simply can't let that one pass.
White people "came to be" in the same process as all other people. As a
member of NOI, I understand you may be opposed to evolutionary
biology, and thus have little regard for what I'm about to write. Even so,
there is a wealth of information and evidence which give credence to the
field, so whether you accept it or not is a matter of faith and personal
belief, and not lack of evidence on the part of Science. Now that I've
finished my disclaimer, on to the science part!
Modern humans all evolved on the African continent, most likely in
Eastern Africa. From there, there were several waves of migration, with
some groups going to other parts of Africa, and the rest making their way
through all the habitable continents. As humans dispersed into new
habitats, time, selective pressures, and genetic drift acted upon them.
Some traits were more successful for certain environments, thus over eons
(assuming these environmental conditions were relatively constant) these
traits were positively selected for. Traits which proved to be too much of
an hindrance were negatively selected against. Thus good traits
propogated and bad ones were shoved to the wayside. Now, some traits
were "nuetral", meaning they had no negative or positive impact on the
individual or group as a whole. Sometimes these traits would go away on
their own, other times the frequency of these traits found within a
population would just happen to increase, to the point where it was
common for most people to possess them. This is random drift to
fixation.
The populations within each migrating group may have come from one
originl mega group, but each subgroup may have had certain random
characteristics. When these groups are isolated and small, prolific mating
will produce inbreeding, which would circulate those characteristics at a
higher frequency. Each subsequent generation that breeds increases the
frequency of the characetristic, until it becomes fixed within the whole
popuation of that subgroup. This is called a bottleneck, because a
relatively few people who mated streamlined their genes into a ballooning
population. When groups are isolated, there is little to no gene flow
between groups, thus some populations will retain or develop
characteristics not found in others.
Gene flow bottleneck, selective pressures, and random drift is what
created so many unique ethnicities, of which White Caucasians are one.
You may ask how they got pale skin or blue eyes. Just last year a study
was published which showed that pale skin is the result of a combination
of alleles for a pigment gene which does not "turn on", so to speak, and
thus produces little pigmentation in their melanin. The reason their genes
for this trait didn't "turn on" could be selective--white skin had an
advantage in colder climates--or it could have been a random, nuetral
mutation in one person in drifted to fixation. Or it could be that it was
originally a nuetral mutation, but new selective pressures turned it from
neutral into advantageous. The same can be said for blue eyes.
OK, that is an extremely simplistic argument, but I hope it correctly
conveyed what I'm trying to say. Sorry 1milehi, but this myth of some evil
scientist grafting white skin onto Black humans a few millenia ago is,
scientifically speaking, utter BS.
