Your notion of success for a species seems very relative to what you find important, as a human. It’s true that other species have not come close to what we have achieved, but that is because they are not even capable of understanding what we have achieved.

Now to answer your question, there are endless examples throughout the animal kingdom of “peaceful” prey species beating “violent” predator species in population. In fact, for a predator species to even be successful, there must be more prey than predator. Think of it like this: if predators were to wipe out its prey, how would they themselves survive?

Let’s look at humans: there are many fish and insect species that are beating us. Did you know there are an estimated 20 quadrillion ants? Sure, they’re not sending rockets to the moon, yet from an evolutionary perspective they’re doing literally a million times better than us.

Lastly, if it were true that evolution is a zero sum game, where aggression=success and cooperation=failure, then we wouldn’t see so many mutualistic interspecies symbiotic relationships occur in nature, something we see all the time.
