The way you think, the things you think, the things you remember, your capacity to think long-term, and the ways in which you socialize are all evolved traits.
Poos inherited genes for eating and digesting excrement, not being mentally sane.
Why? They went through a population bottleneck where the only available food (besides meat which they were forbidden from eating) was literal cow dung. Those who could eat the dung survived & reproduced. Those who could not eat the dung died & failed to reproduce. They're much like house flys which often lay their maggots in cow dung around farms, the maggots eat the patty as they grow.
