Wade states, however, that there are reasons to reconsider the study of it; the genetic differences between races may give evidence of the different evolutionary pressures they faced, and the differences may be medically relevant. Citing Neil Risch, Wade puts forth that there are five continental races Africans, Caucasians, Asians, Pacific Islanders and Native Americans[nb 1] which are made up of smaller subdivisions called ethnicities. Other positive reviews came from Publishers Weekly; Kirkus Reviews, who called the book "meaty, well-written"; and The New York Review of Books, who said that it was "on the whole, a fascinating account of recent scientific findings.".

^ Wade defines these continental races as follows: Africans are those whose primary ancestry is in sub-Saharan Africa, including African Americans and Afro-Caribbeans; Caucasians are the peoples of Europe, the Middle East, North Africa and the Indian subcontinent; Asians are the peoples of eastern Eurasia, such as those of China, Japan, Indochina, the Philippines and Siberia; Pacific Islanders are Aboriginal Australians and the peoples of New Guinea, Melanesia and Micronesia; and Native Americans are the indigenous peoples of the Americas. .

He references Noam Chomsky's theory of "universal grammar" a term that refers to both the hard-wiring of the brain that allows children to learn grammatical rules, and the underlying grammatical similarities of all human languages. Wade cites a number of evolutionary psychologists for an explanation, including Robin Dunbar, who argues that language evolved because it was a more efficient way of establishing social bonds than grooming; Geoffrey Miller, who suggests that speech was a signal of intelligence and thus evolved through sexual selection; and Steven Pinker, who thinks that the ecological niche of humans required the sharing of knowledge. Wade writes that the genetic basis of language is linked to the FOXP2 gene, as it shows signs of significant change in humans but not in chimpanzees, and that mutations of it cause severe speech disorders..
