It would need toes of the same size on each side and a symmetric knee plus muscles to control it, I think it would need a leg and foot or hoove design completely independent from the outer ones, it couldn't copy or reuse the existing design, so less likely to evolve.
But if the kangooroo tail counts as a leg, it's indeed very different, but symmetric.
- kijin 7y agoYeah, it would seem that we have plenty of three-legged animals already. A stout tail is what you get when you try to make a third leg that is perfectly symmetric and optimized for being positioned in the middle.
