In his 2007 book “A Farewell to Alms,” the economic historian Gregory Clark argued that the English came to rule the world largely because their rich outbred their poor, and thus embedded their superior genes and values throughout the nation. In her comprehensive takedown, the historian Deirdre N. McCloskey noted that Clark’s idea was a “bold hypothesis, and was bold when first articulated by social Darwinists such as Charles Davenport and Francis Galton in the century before last.” Indeed, over the past 150 years, various white Western scientists and writers have repeatedly offered biological explanations for Caucasian superiority. They have repeatedly failed because, as McCloskey noted, none ever mounted a credible quantitative argument.

Now, in “A Troublesome Inheritance,” Nicholas Wade, a longtime science writer for The New York Times, says modern genetics shows that “the three major races,” Africans, Caucasians and East Asians, are genetically distinct races that diverge much as subspecies do, and that their genetic differences underlie “the rise of the West.”

Out bred? without Contraception? more likely rich children lived.
