@Javier aren't we ambush predators and trappers, necessarily, by nature? Like, the whole outlast predator thing never made much sense to me, because it's such a poor cost to benefit ratio, and also so much more effort than ambush and trapping, which would have likely come to early humans pretty easily, given that who we evolved from was already socially cooperative - so as soon as we mutated for high cortical growth, we'd probably be planning ambushes, if not even before then? Conjecture though
