I look at my dog, a prime example of a smart none humanoid life form.
There I am inclined to disagree, I have a dog and have observed many others and smart is not a word I would associate with dogs, capable of often limited repetitive task learning sure but not much else. From my experience most canine smarts are the result of humans anthropomorphising the animals and not any great intelligence on the pooches part. Though I'd reckon that different breeds may demonstrate differing levels of capability. So we would easily have the superior intellect, we can appreciate our situation, can use tools, mitigate our environment as opposed to being in its thrall, improve our situation, leave the planet and so on; note, that superior intellect does not mean must live in complete harmony with nature.
I just don't think that we are anything special.
Indeed we are not but I'm not suggesting that we are the
exemplary template that all must follow to have success, merely that the very basic set up works self evidently. I'm just approaching this purely from a biological point of view, one which makes no judgments on the moral merits of humanities actions so far.
Hope is but the first step upon the road to disappointment.
