In 1933 it can hardly be alleged that Prehistory is a useless study, wholely remote from and irrelevant to practical life. In one great country at least, interpretations of supposed facts of Prehistory, imperfectly apprehended by an untrained mind of undoubted genius, have revolutionized the whole structure of society. No one who has read Mein Kampf, or even the extracts therefrom in The Times, can fail to appreciate the profound effect which theories of the racial superiority of ‘Aryans’ have exercised on contemporary Germany. In the name of these theories men are being exiled from public life and shut up in concentration camps, books are being burned and expression of opinions stifled just as, in the name of religious ideas, they were during fifteen long centuries of darkness.

7 Baur, p. 67 : –Difference in the shape of the skull, the structure of the brain … in a word the numberless morphological and physiological distinctions between the various races of man depend in each case upon very numerous heredity-factors, with the result that as yet we how little about the course of their inheritance—. Fischer, pp. 119 and 151, and Ruggles-Gates, pp. 42 and 323, point out the alterations in skuilform and stature produced by non-hereditary post-natal factors. Such alterations cannot be distinguished from hereditary traits in individual cases, though in large populations they might be discounted statistically.
