If the show had an idiom for survival of the fittest, what would it be?

In Equestria, it's survival of the friendliest. I mean...friendship is literally a weapon that can conjure a rainbow laser to blast away or brain wa-er, reform the bad guy.

Survival of the fittest works fine. It's not people-specific like saying 'Social Darwinism' or some-such.

Yeah, I’ve got to go with 6784405’s answer. Friendship is magic.

Well, seeing as Equestria has dinosaur (excuse me, "pony-saur") fossils lying about underground, we can assume there was some big cataclysmic extinction-level event in the world's distant past. "Survival of the fittest" as a term was either coined or popularized by Darwin to describe the ability of species to adapt to change. Probably fine to use it as is.
