this aught to get the panties of any cat lady viewing all wadded up. scientific division of races by measured differences; 

 

This is not a volume for conformists, in the sense that it does not spend much time beating down threadbare orthodoxies: that race does not exist, that IQ tests are biased, that environment and “racism” explain racial differences in achievement, etc. Prof. Lynn quickly summarizes the arguments in these areas, but writes mainly for an audience that already understands that race is real and that races differ in intelligence. His main interest is in assessing IQ differences, determining to what extent the differences are genetic, and sketching out the events of the past 100,000 years that probably caused these differences. It would be hard to imagine a clearer, more capable treatment.

‘Genetic Clusters’

Prof. Lynn divides homo sapiens into ten racial groups based on genetic similarities that follow traditional anthropological classification. He notes that before the vogue for pretending it does not exist — a vogue limited essentially to the United States — there were straightforward definitions of race. As a textbook from 1976 explains: “[R]aces could be called sub-species if we adopted for man a criterion from systematic zoology. The criterion is that two or more groups become sub-species when 75 percent or more of all individuals constituting the groups can be unequivocally classified as belonging to a particular group.” Prof. Lynn points out that one of the book’s authors, Luigi Cavalli-Sforza, now famously insists on writing about “genetic clusters” rather than races.

There are four recognized sub-species or races of chimpanzees, and two races of gorillas. There are as many as 79 different breeds of dog, and Prof. Lynn lists a few striking biological differences in human races. Almost all Amerindians, for example, have type O blood, and virtually no Australian aborigines have type B. Disease rates vary so much by race there is even a journal called Ethnicity and Health devoted to them. Europeans, for example, are 6.6 times more likely than East Asians to carry the gene for the disease phenylketonuria (PKU). Pygmies average about four feet seven inches in height. It is only with respect to their own species that some people refuse to see the obvious...........more...........
