-And yet—it seems like humans _are_ special, in some ways. Of all the creatures on [the tree of life](https://en.wikipedia.org/wiki/Tree_of_life_(biology)), our lineage "took over the world" in the sense that if humans want a resource that cats or crows or octopuses are using, the nonhuman side of the ensuing conflict is predictably going to lose. (To the extent that we don't usually think of ourselves as engaging in a "conflict". Animals aren't _enemies_; they're just in the way.) This is not because humans are stronger or have sharper teeth than other creatures, but because of something about our "intelligence" in the natural-phenomenon (not the IQ-test variation) sense. It's not even necessarily about _individual_ human intelligence being a particularly formidable force: given no tools and no friends, and confronted by a hungry lion at ten paces, it doesn't seem easy to survive by thinking of some incredibly clever plan. If you had a gun, you could shoot the lion, but [no one individual knows how to make a gun](https://en.wikipedia.org/wiki/I,_Pencil) all by themselves, starting from nothing.
