So, here is the latest finding about the part of the human family tree that we've been discussing. From the journal; "Archaeology, Ethnology & Anthropology of Eurasia". Reprinted in the latest New Scientist magazine:

It shows clearly that there is no such thing as a 'mosaic' structure to humanity. The subsaharan African branch has been seperated from the European, Chinese, & Papuan branches for well over 100,000 years.
Biowatch & Galaxian have linked other tables & graphs earlier in this thread showing the distance between various local humans populations. They also showed that mosaic is a political confabulation to serve a social agenda.
No doubt there are some genes that are found in well separated populations. That's not a big deal. Spontaneous mutations are allowed to happen all over the world; downs syndrome, huntingtons chorea, sickle cell, hemophilia, UGT1A1, etc. And for whatever reason, some become established (such as sickle cell's advantage in Malarial areas).
But before the age of air travel distant populations had very little interaction for several tens of thousands of years. The reason for the lack of interaction was;
a) Difficulty & long duration of travel.
b) Dying from foreign diseases if travel was attempted by the foolhardy.
c) Being killed for invading other's territory. Only local mating transfers were acceptable.
These factors of isolation made racial differences significant enough that two more factors became important;
d) Significant cultural & language differences creating further dislike & suspicion.
e) Further genetic divergence so that races looked different & then became actual subspecies.
Which created yet more divergence, leading to;
f) 'General' reluctance to interbreed (except for fetishists).
g) Actual cross-sterility, tending to full speciation (ie; hybrids are unlikely, & have high incidence of dying).
So we have some 7 points, starting from the trivial & developing to the major & insurmountable.
It is only in recent decades that safe travel by air, sea, rail, & highways, have enabled some interbreeding. And then, it is only by high tech medical intervention that a lot of cross sterility has been over come...but needs to be repeated generation by generation, because the sub-species divide is so persistent.
Speciation is a law of Nature. I mentioned before that even if we seed an empty world with a totally homogenous population of absolutely identical clones, & we have perfect travel & communication between them. So long as there is no medical intervention, & forced eugenics programs, & forced social control; the population will fragment into different cultures & phenotypes & subspecies, then species. And that is with the above perfect scenario.
Therefore, given the above 7 points operating in an imperfect world, not seeded by clones, the fact of present human subspeciation is an absolute reality that can NOT be denied by truthseekers.
