Evolution is frequently driven by competition between members of the same species, independent of resources available. Witness the elaborate feathers of many birds of paradise which evolved to secure mating partners, or the antlers of deer which serve during ruts to compete for harems of does.

- maxbond 4y agoI feel as if I'm repeating myself but that doesn't address whether or not that's true in this case or address the reasons I've provided for why I don't think so. Afterall I mentioned peacock feathers in one of my first comments, I'm aware of intraspecific competition. Since we've made two laps around this point I suspect we'll have to agree to disagree.

Hence the reasoning above that the human intelligence evolved in competition with something that required increased intelligence to overcome; the only such thing on the planet throughout human evolution is other hominids. Evidently, this is simply a hypothesis, and doesn't exclude other evolutionary pressures.
