The females are bigger than the males in most species on the planet including, insects, molluscs, fishes, and reptiles. Mammals and birds are the exception; they contain only patriarchal species in which the males are bigger, stronger and more dominant. Mammals and birds must have evolved a patriarchal gender balance independent of eachother as well as intelligence.
Some say that cephalopods are intelligent because they can be conditioned to repeat certain behaviour but they are very r-selected; they lay around 100 000 eggs at a time and don't raise their offspring. Birds and mammals are intelligent and are taught about the world by their parents at a young age, especially if the father partakes too.
It appears as if intelligence, teaching and monogamy* only appear in patriarchal species which are a minority on the animal kingdom.
*Though there is a norm of monogamy among many species, female cheating has been observed in all known species of birds except for one.
The pattern among mammals is probably similar.
