[Discussion] Intelligence is only found in patriarchal species.

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.
