>>13777831>>13777639brain power is moreso related to predation than "environmental complexity". he's right in what he's saying but i just wanted to add that point. and it's not like predator = bigger brain = better brain. it's just that you need a lot of complicated thought to prey on anything that moves. your environment has more to do with what happens to your sensory organs. you might think this is related, it sort of is (to brain processing power) but evolution would work in the step by step way of
>1. sensory organs change in response to environment>2. less information = less need for big brainbut it'd be slow, and there's no way of knowing if there would be some other benefits conferred by having a good brain that would cause it to be beneficial.
for your question though OP it's way too subjective to be answerable in general. i don't say that to be disparaging, it's a good question, it's just a very subjective one.
