We also act out of instinct
@Rocky998 . And we have to stop and decide what intelligence is, and what it means. We can do remarkable things within the confines of how our brains work. But if you look at the current, quickly developing research on animal cognition, there is a lot of intelligence in this world. We aren't that special - we just have abilities no other other species has (while some of them have skills we can only dream of. If we could see like we are learning some other species see - wow).
We're seeing strong evidence of problem solving, memory, emotion and other mental skills in our fellow animals - it's one of the most intriguing new avenues in science right now. As a human, I've learned to keep my jaw from dropping too often when I look at this stuff. I doubt I'll ever get my head around the implications of it, if there are any different than how we act toward other species from our own instincts.
I would have completely denied the possibility of what's being found when I was 16. It completely goes against everything I had been taught back then. Now though, I have an ever growing respect for what is happening in the heads and nervous systems of other creatures.
