Although the term "ossicle" literally means "tiny bone" (from Latin ossiculum) and may refer to any small bone throughout the body, it typically refers specifically to the malleus, incus and stapes ("hammer, anvil, and ...
Andreas Vesalius, in his De humani corporis fabrica, [7] was the first to compare the second element of the ossicles to an anvil, thereby giving it the name incus. [8] The final part of the long limb was once described as a "fourth ossicle" by Pieter Paaw in 1615.
The evolution of mammalian auditory ossicles was an evolutionary process that resulted in the formation of the mammalian middle ear, where the three middle ear bones or ossicles, namely the incus, malleus and stapes (a.k.a.

The stapes is commonly described as having been discovered by the professor Giovanni Filippo Ingrassia in 1546 at the University of Naples, [13] although this remains the nature of some controversy, as Ingrassia's description was published posthumously in his 1603 anatomical commentary In Galeni librum de ossibus doctissima et expectatissima ...
The anvil (a middle ear bone) more resembles those of chimps, gorillas, and Paranthropus than Homo. [24] Like H. habilis and H. erectus, H. naledi has a well-developed brow-ridge with a fissure stretching across just above the ridge and, like H. erectus, a pronounced occipital bun. H. naledi has some facial similarities with H. rudolfensis. [22]
