It has generally been assumed that the process that could transform this: into this: was a drawn-out evolutionary slog, taking many generations of human-canid interaction to achieve. But as Tim Flannery notes in a recent review of several new titles on the subject for The New York Review of Books, Lee Alan Dugatkin and Lyudmila Trut’s How to Tame a Fox (and Build a Dog): Visionary Scientists and a Siberian Tale of Jump-Started Evolution offers a fascinating look at the groundbreaking discovery that revealed that the process of domestication, once thought to have taken thousands of years, could be compressed into decades: “Profound insights into how dogs evolved from wolves come from a remarkable, multidecade experiment on foxes that was carried out under the supervision of the Russian geneticist Dmitri Belyaev from the 1950s onward. … Belyaev’s experimental method was simple in the extreme. Out of the thousands of silver foxes held at a fur farm, he simply selected for ones that were calmer than normal in the presence of humans. After just a few generations of selective breeding, some offspring of these slightly tamer foxes started to seek out human company. Breeding these individuals produced foxes that showed changes . . .
