We think of dogs as man’s best friend. They sleep in our beds, they dominate on Instagram feeds, they shape our public parks. But do dogs also hold the key to our survival? 20,000 years ago, the gray wolf started the long evolutionary process to become our beloved household pet and changed the course of humanity in the process.
