"The Dog in the Fox – The experiment that replayed 10,000 years of evolution" details the most famous experiment in the history of genetics. In 1959, Soviet scientist Dmitry Belyaev started a secret farm in Siberia to domesticate silver foxes. His method was simple: He bred only the foxes that were least afraid of humans. Science writer Elena Furr describes the astonishing results. Within just a few generations, the aggressive foxes didn't just become friendly; they changed physically. They developed floppy ears, curly tails, and spotted coats—traits associated with dogs. Belyaev discovered "Domestication Syndrome," proving that selecting for behavior (tameness) accidentally drags along physical changes. "The Dog in the Fox" is a window into our own past. It explains how the wolf became the dog and suggests that humans may have "self-domesticated" in the exact same way, trading aggression for cooperation and changing our own biology in the process.
