Why do we have 10 fingers and not 8?
Because we evolved from fish that had 5 bones in their fins. All vertebrates follow the same pattern – 1 bone, 2 bones, lots of bones. As to why the fish had 5 fin-bones, it was probably simply how it evolved – the optimal number of fin-bones to maintain the fin structure.
