Dr. Philip Rushton, using a scientific method of statistical
analysis, compared the IQ ratios of representatives of different
races, as well as the size of the brain, limbic system and the
volume of hormones secreted by the glands. This scientist -
Darwinist, proved quite obvious things about early puberty
in Negroids and late in Asians. He quantified the release of
estrogen, testosterone, dopamine, and other hormones. In
general, Rushton has done a colossal titanic job of collecting
and processing data. But instead of criticizing his methods,
or his information, opponents from "science" began to personally
criticize Rushton, as well as his Darwinian views.
Say, the differences between the races are only some 0.1%
of the DNA. But there is only 2% difference between humans
and the same chimpanzee bonobos. In addition, 0.1% of the
DNA molecule code contains at least 3 million nucleotide
pairs distinct from each other! And this is not so little as it
might seem in percentage terms.
At one time in the film National Geographic - "The Great
Human Odyssey" it was stated that 95% of the immune genes
of Papuans and Australians belong to Denisovans and Neanderthals.
Which leads to the resistance of these races to most tropical
diseases that kill white people in a matter of weeks. Which,
however, is also not politically correct.
However, Dr. Rushton found that blacks have larger hormonal
glands than whites, and that there are differences in brain structure.
Which leads to their early puberty, as well as excessive hot temper
due to the higher concentration of hormones in the blood. That is
why black people are so restless. All this and much more you can
learn in it in the book banned in the USA called "Race, Evolution,
Behavior".
