Here's the thing, you are simply failing to understand what I have said. Curiosity is a fairly simple characteristic. It means "inquisitive" and that's all. Lots of living things are "curious" as we've already discussed, including humans. However, humans have something more than simple curiosity. You want to lump it all in together and make it curiosity too, but we can see that is not the case.
Mankind retains the characteristic of inspiration to go along with curiosity. Not only are we curious, we also are inspired to find answers and understanding. It is the inspiration driven by curiosity, of which I am speaking, and you don't want to recognize. But it is YOUR argument which fails the test of logic here. Regardless of 'semantics' or word understandings, you must admit, humans have achieved far more than any other species on the planet. If simple curiosity were the explanation, some species would be competing for 2nd, and we don't see that. Nothing else even remotely comes close to human achievement. So there has to be some other characteristic in play, curiosity alone, doesn't explain it.
Do other animals learn from curiosity? Perhaps, but they lack the inspiration to explore and find answers and understanding. Humans clearly have something different than the rest. I've been calling it 'inspiration' here, for lack of a better word, but I suppose you could call it 'humanity' as well. Whatever it is, nothing can dispute it's considerably more than the simple 'curiosity' found abundantly in the animal kingdom.
