Why is there two bones in the shin? No, it's just a nice animation-we're not suggesting that one of them be "removed"😁 Why does the tibia and fibula have two bones in the tibia? There's just one bone in the hip and that's fine. Where is the physiological and anatomical point here? The point is that our ankle is a very complex structure. The tarsal (the same as the wrist, only in the foot) has 7 bones that interact with the 5 bones of the metatarsal, which in turn are connected to the 14 phalangeal bones. Such a complex structure is physiologically impossible to be flexible when connected to only one bone. Otherwise, we would walk like tin soldiers (at best😁) That's why we have two bones in the tibia, and with them a structurally complex musculo-ligamentous apparatus. By the way, exactly for the same reason, there are also two bones in the forearm☝🏻
