Depends:
Is intelligence genetic?
Are seers particularly...I'll be polite and say prolific?
Is there any reason there intelligence would have to shift either direct:
Crocs and sharks have been "left alone" for eons, neither seems ready for Jeopardy college week, but I'd never call either dumb.
Still get by just fine all in all
Idk, as far as I'm concerned asking is it intelligent should almost always be followed with does it need to be intelligent?
And of course it would help if someone would make a good definition of the word....
