I have hands that can turn into fists. Does that mean I was created for hitting things?

This is your logic, woman!

I mean, unironically... from an evolutionary pov, yeah kind of. I don't know specifics about how hands evolved, but knuckles seem to be shaped a certain way for reasons. I imagine big, boney knuckles was a trait that got successfully passed down due to its usefulness.

I am not an evolutionary biologist, so I could be wrong. Evolution is weird and counterintuitive sometimes.

If you look at how Gorillas kind of walk around on their fists, it definitely makes sense that there's some evolutionary benefit to the knuckle shape. It doesn't have to be related to hitting things either. It's easiest to support yourself with a straight wrist, like if you're holding a branch, vs putting your palm flat is a lot more stress on your wrist.
