Inbreeding in Animals

[Slim]

Does inbreeding happen/has happened in the wild?

Probably not much in warm blooded animals just based on their social behavior...young wolves are run off to find their own packs, other large roaming animals cover lots of ground which further's their chance to outbreed. I do wonder about animals like orcas and dolphins live in family pods.

In cold blooded animals, it's most likely more common. I'm thinking of large frog populations in a small pond, and turtles who may not roam far from their place of birth during their lives.
