i like to persuade people by having them imagine an isolated tiger who hasn't eaten anything in a week. by force of nature their sense of smell, hearing, etc. must all be heightened so as to ensure their survival.
but a tiger has evolved to be an apex predator, and not much else.
our predatory speciality is more about leverage than brute force, or scavenging rather than hunting. so i think the logic still applies that cognition can be improved in a way that is beneficial to modern humans. resourcefulness implying that resources are found / conjured when they appeared to be lacking?
