I think it's because humans think. We have too much intelligence for our own good. Or perhaps to little. It's a confusing thought but if we didn't have brains large enough to have emotions and desires then I don't think we would cause so many problems. For example...rabbits. You heard me I said rabbits, they don't have large brains, all they have to think about it eating to survive and then reproducing then raising the baby then eating some more. Surival, and reproduction are the basic elements of any animal. As far as I know(correct me if you have evidence) humans are the only ones who desire more than survival and prolonging of the life of their species. We want power and we want to advance, to be be "better".
So in that way you could say we have to much intelligence for our own good. But maybe it's too little, maybe if we had more we would have the foresight to realize we are causing serious problems in the world.
LoL
Anything with a brain 'thinks'
Do you separate us from rodents because of out high complexity? Rabbits live for more then sex and grass, they are creative and practical, (study a warren) yes, it can be considered instinct driven, but so is humanity. Everything we learn, deduce, and invent can be broken down to instinct. Other species learn and develop, not to the same extent, but dolphins, birds, various primates, communicate and the likes.
I'm a bit tired at the moment, but I have debated about this for a while with various philosophical groups, humanity is different, yes, but nothing unique, beyond the degree of separation.
*yawns* Sorry, I don't mean to condescend, and the lol at the start just signifies my smile at this age old argument.
