Talk about logical fallacies:
Do we “not need” long toes because our toes are “not used” for hanging from trees? Or do we not hang from our toes because we can’t?
Although it seems unlikely to me that I could, it is even less likely I'll ever be completely sure.
Human feet are pretty interesting. They obviously were going through a similar change that horses feet did - losing toes to eventually form one giant toe (hoof) - but that evolutionary change was short-circuited by the development of our large brain. If we had remained only as smart as a horse, perhaps our feet would look more like a horse’s foot, too. As it is, our feet are dominated by one large toe, three smaller ones, and a near-vestigial little toe (wee-wee-wee, all the way home).
