Mysteries of skulls

Modern scientific data prove that the size and shape of the skull (i.e. morphological features) do not affect human intellectual abilities in any way. But more recently by the standards of history in Nazi Germany (and not only!) there were special sciences including eugenics which proved by measuring the skull belonging or not belonging to the Aryan race. Inside the large races (Negroid Caucasian Mongoloid) there are groups with different skull forms (dolichocephalic - long head brachycephalic - broad head mesocephalic - middle head). Scientifically proven facts show that brain size and weight are also not reliable criteria for assessing intelligence. Characteristically the capacity of the brain box of Mousterian fossils - Neanderthals - is no less than that of living people. As for modern races Mongols not Europeans have the largest brain volume and weight while the average brain weight of the British and Japanese is approximately the same. But inside the same race there is also a big variation of brain size and weight.
