I was walking my dog this morning when I thought was there ever a time when carnivores, predators, were not hunters? Dogs, for instance, do they have a known ancestor who was not a meat-eater? My guess, and I admit that it is only a guess, is that most carnivores developed from omnivores. It’s hard to see an herbivore, say a sheep, turning into a carnivore, whereas there are instances of omnivore’s being superb predators (bears!). So what do we know about dogs, wolves, foxes, jackals, hyena and coyotes earliest ancestors? What were their habits, and what did they eat?
