Ironically, it was the monkey's need to be an expert hunter gatherer that brought it to its apex status with intelligence. Then the monkey traded it all away for "security". There was a natural environmental pressure to be intelligent in nature as the monkey had to know what was safe to eat and where to go. This jack-of-all-trades attitude was traded for experts that are seemingly useless outside of their field of expertise. A diverse omnivorous diet for traded the security of the same bowl of grains every single day. The monkey traded a 4-5 hour workday for endless toil, but hey at least the monkey wasn't getting rarely eaten by tigers now.
