what asker said above.
of course there are some animals that have hierarchical social structures, and there are animals that use tools, and there are animals with certain specializations, etc. none of that conflicts with a thoughtful critique of civilization.
the animal kingdom - including humans, of course - has a level of diversity that is almost unfathomable, even within species. some bees, for example, are biologically different from others, making them better suited to being, say, "workers". not unlike how men's general physical size and strength made them more adapted to certain tasks (eg, hunting) than women, and vice versa. i don't mean to be resolving the chicken/egg question around this (were men strong first, then decided to do the heavy lifting; or did they become strong from heavy lifting), and i don't really think it can be.
there are biological realities that life seems to adapt quite well to. but the hierarchical structures (and levels of specialization) imposed by civilized humans - on all forms of life - has little (if any) biological imperative that i can detect. most of that shit comes from the scheming civilized human mind.
