Stories About Dogs | 60 Minutes Full Episodes
In a Nutshell
Dogs evolved from wolves around 20,000 years ago through "survival of the friendliest," with genetic mutations on chromosome 6 enabling human bonding, as shown by Duke's Brian Hare comparing dog and wolf pups, and parallels to human Williams syndrome. Comparative oncology leverages dogs' shared cancers (e.g., osteosarcoma, glioblastoma) for faster treatments via NIH DNA studies and trials like Listeria immunotherapy, benefiting both species under Cancer Moonshot. Chaser, a border collie knowing 1,000+ toy names and sentences, proves dogs' advanced cognition; Emory fMRI scans confirm genuine love via reward-center activation to owners' scents and oxytocin from eye contact.

Many viewers have a dog nearby. Dogs evolved from wolves, but how and when remains a mystery. DNA of dogs and wolves provides intriguing clues about their and human evolution. Survival of the friendliest best describes dogs' evolutionary success, according to Duke University scientist Brian Hare. There are an estimated billion dogs on the planet. They live with us, work with us, and love us.
What is it you're trying to understand about dogs? I'm really interested in where dogs come from. I think it teaches us a lot about where humans came from.
Brian Hare, evolutionary biologist and author at Duke University, has studied animal evolution for 25 years.
I think what really summarizes the link between dog and human evolution is survival of the friendliest.
What about survival of the fittest? Survival of the fittest is a misconceived idea in the public mind of what evolution is. It's the idea that the biggest, the strongest always win. Might makes right. But not at all. Dogs are exhibit A of this.
Sweet dogs started as wild predatory wolves. Their evolutionary story began at least 20,000 years ago when humans were hunter-gatherers. Wolves chose humans; a population became attracted to humans, gaining advantage by eating garbage around homes. Wolves that gave up hunting and were friendliest toward humans had a huge advantage. Some wolves fed off scraps, weren't aggressive, and over time became domesticated.
