I support the unchanging backbone. People who do not understand that the same biological species cannot have different breeding strategies in males and females.
If the animal adheres to promiscuity - then both males and females, and if it creates long-term coupled relationships - then also all species. There is no eight-legged Argonaut with a harem, or strong family pairs in bees. So men who love polygamy, I recommend to carefully look at their children, if not enough.
