Evolutionary seen, it all started with the chorda dorsalis (which we only have when we are foetusses and disappear in time) which would be surrounded by a layer of Cartilage (the same as your ears), by time the animals grew a cranium and multiple other cartilage bones which all had their function (as they were fish, they got their fins). Eventually to become better resistant to the world, the cartillage changed in real bone (full of Ca), and as those fish became Tetrapodamorpha, the fins became cluttering together to become what you see now as your legs and arms. Conclusion, all bones look different, because they all had/have their function (the past term as because eg the stuit is completely useless)
