"...in general high intelligence is not a particularly useful adaption. Sure we are numerous and dominate our planet for the last few-thousand years. The Sauropods managed that for 100 million years."
Extremely bad comparison. Humans are unique in that we lack almost any physical adaptations to the environment. Sauropods had every physical adaption needed to survive as long as they did. The only thing we have is intelligence. Not only is it a useful adaptation, it is our ONLY adaptation.
I expressed myself badly. I was merely trying to downgrade the idea that humans, with their intelligence, represent some kind of pinnacle of evolution that can regard itself as far more successful than past species.
Not remotely true.
