In reality, creativity is, perhaps, our only advantage when trying to not get killed by other animals. Picking up a stick and fighting off a larger animal -- great example of creative solution. It's novel.
Before, no one ever thought to pick up a stick. Perhaps sticks were viewed as merely lying there, to be carefully avoided in case somebody steps on one. Maybe those who tried to pick up sticks were viewed as crazy, sinful by some sort of primitive Republicans (not that Republicans now are more evolved :)... I mean, who cares about sticks, animals were usually fighting with their own teeth, hands, or horns (I wish I had a horn).
It's not until an animal with a stick has beaten the shit out of another animal without a stick for calling him crazy, that the sticks became a useful tool.
I mean, face it -- we're just animals, and without creative approaches to our problems we wouldn't be talking about this on a giant electronic mind-network-thing.
