The video explores how animals became domesticated, focusing on a 1960s Siberian experiment with silver foxes. Scientists bred calm foxes to reduce aggression, showing that behavior can be inherited like physical traits. The experiment also demonstrated that environmental factors influence behavior. The video concludes with examples of other animals evolving, such as horses, cats, and dogs.
