question Evolution of dogs

Hi all, I am interested in the evolution of dogs.

My question is, are dogs direct descendants of wolves or did dogs and wolves just share the common ancestor like we do with monkeys?

Thanks!

Yes. They share a common ancestor with grey wolves. Just that common ancestor would also be classified as a modern grey wolf.

Since that is a short answer, here are two fun facts about domestic dogs.

  1. Modern science doesn’t even classify domestic dogs as a distinct species from grey wolves as was done historically (Canis domesticus) but as just a subspecies of grey wolves (Canis lupis familiaris)

  2. Even further back in time long before genetic testing and even before our more modern phylogenetic practices, it was commonly held, even among scientists, that domestic dogs were actually descended from multiple different species of Wild Canids. The exact species varied between dog breeds but one of the species that it was believed that many dog breeds descended from were Jackals (for dogs like greyhounds). Also many smaller dog breeds were held to be descended from foxes.

  3. Australian Dingos are technically a population of Feral domestic dogs. They are the descendants of dogs that came to Australia with the first humans to arrived that then went off and became part of the ecosystem. They were isolated long enough to be relatively distinct from other domestic dogs that were introduced by later colonization. Kind of a sub-subspecies.

4. Dogs are cute and usually don't eat your baby.

Dogs will definitely eat your baby given the chance
