some tree species self-selected themselves for height (ie. there’s no point in being a tall tree unless taller trees are blocking your sunlight)
humans were not the first species to self-select (for humans, the trait being intelligence) (although humans can now do it intentionally, which is a qualitatively different level of “self-selection”)
just a loose thought, probably obvious
