Clemants and Professor Kirowan had just engaged in a somewhat testy anthropological argument: Clemants upholding the theory of a separate, distinct Alpine race, while the professor maintained that this so-called race was merely a deviation from an original Aryan stock – possibly the result of an admixture between the southern or Mediterranean races and the Nordic people. “And how,” asked Clemants, “do you account for their brachycephalicism? The Mediterraneans were as long-headed as the Aryans: would admixture between these dolichocephalic peoples produce a broad-headed intermediate type?” “Special conditions might bring about a change in an originally long-headed race,” snapped Kirowan. “Boaz has demonstrated, for instance, that in the case of immigrants to America, skull formations often change in one generation. And Flinders Petrie has shown that the Lombards changed from a long-headed to a round-headed race in a few centuries.”
