The biological racism of late 19th century Darwinism is now both well documented and widely publicized. Especially influential in the development of biological racism was the theory of eugenics developed by Charles Darwin’s cousin, Sir Francis Galton.2,3
Less widely known is that many evolutionists, including Darwin, taught that women were biologically and intellectually inferior to men. The intelligence gap that Darwinists believed existed between males and females was not minor, but of a level that caused some evolutionists to classify the sexes as two distinct psychological species, males as homo frontalis and females as homo parietalis.4 Darwin himself concluded that the differences between male and female humans were so enormous that he was amazed that ‘such different beings belong to the same species’ and he was surprised that ‘even greater differences still had not been evolved.’5
