Actually thats a good point. If the notion is that it’s the ability to augment your natural abilities through other actions and tools, what does it matter if YOU come up with the method or you observe it or were taught it?
While I believe it has been shown that Mike’s original stance, that it was uniquely human to extend our natural abilities beyond that which our morphic traits dictate, is wrong (thanks mainly to the diving spider, and to some extent the capuchins) What I will acknowledge is that humans key distinction is the level and complexity that we take it over all aspects of our existence.
We are the supreme tool users/makers and through this it have given us the technology to become the dominant organic force on the planet. ( with germs and viruses a close second) but as it seems clear this extended tool use is just an extension and refinement on tool use in other creatures to expand into areas that their morphic traits wouldn’t normally allow. This doesn’t mean we shouldn’t marvel at our skills or not realise the massive advantage that they give us as a species. Some creatures can run fast, some can fly, some can dive to extreme depths, some can shoot scalding chemicals from their rear, some can navigate by sound, some can see heat some can make and use tools. But when it comes to tools we are the masters.
