Where did domesticated dogs come from? In 1959, Dr. Dimitry Belyaev began an experiment to answer that question. Although the experiment was illegal in the U.S.S.R. and could have cost him his life, through hard work and a little luck, he not only conducted the experiment, but he also began unlocking some of the mysteries of dog and animal domestication. In this episode we explore the famous Farm Fox experiment, its risks, its controversies, and what we have learned from this research.
