Wikimedia Commons The Russian scientist who revealed the evolutionary secrets of animal domestication has died, aged 91. Lyudmila Trut and her mentor’s experiment began when they started breeding wild silver foxes in 1958, with the goal of producing tamer animals. They found that, within just a few years, the foxes had become not just friendlier but more dog-like, with floppy ears, less muscular bodies, and curlier coats and tails — traits seen in other domesticated animals, suggesting that breeding for tameness brought forth a “suite” of genes. The experiment was a bold move in postwar Soviet Russia, which was then still in thrall to Trosim Lysenko, whose pseudoscientific denouncement of “Western” genetic science exacerbated famines that killed millions, and who had other scientists arrested for researching evolution. |
