The inner ear may not seem like a particularly bony place, but human ears in fact have three small bones (also known as ossicles): the malleus, the incus and the stapes. While most people would assume that these bones are necessary for hearing, one would not imagine that they relate much to how we walk.
Yet according to Chinese and American scientists working together for a study in the journal The Innovation, the ear bones of ancient apes can teach us a lot not only about our primate ancestors, but also about ourselves.
