This process involved the transformation of some bones of the [[Reptile|reptilian]] jaw into three bones in the mammalian middle ear, known as the [[Auditory Ossicles|auditory ossicles]]: the malleus, incus, and stapes.<br /> <br /> ==Overview==<br /> <br /> The evolution of the mammalian auditory ossicles is one of the most well-documented and important evolutionary events, demonstrating a significant transitional stage in mammalian evolution. This process is a classic example of [[Exaptation|exaptation]], where structures originally evolved for one purpose are later adapted for a new function.<br /> <br /> ==Evolutionary Process==<br /> <br /> The transformation from jaw bones to ear bones occurred over a long period of time, starting with early [[Synapsid|synapsids]] (mammal-like reptiles) and ending with true mammals. The two bones that were part of the lower jaw in early synapsids, the articular and quadrate, eventually became the malleus and incus in mammals. The stapes, however, is a bone that has always been part of the ear in all tetrapods.<br /> <br /> ==Significance==<br /> <br /> The evolution of the mammalian auditory ossicles has been significant for several reasons. Firstly, it has allowed mammals to hear a wider range of frequencies than their reptilian ancestors. Secondly, it has provided evidence for the theory of evolution, as it is a clear example of a transitional form.<br /> <br /> ==See Also==<br /> <br /> * [[Evolution of mammals]]<br /> * [[Mammalian evolution]]<br /> * [[Evolution of the ear]]<br /> <br /> ==References==<br /> <br /> &lt;references /&gt;<br /> <br /> ==External Links==<br /> <br /> * [http://www.bbc.co.uk/nature/life/Mammal Evolution of Mammals] (BBC Nature)<br /> <br /> [[Category:Evolution]]<br /> [[Category:Mammalogy]]<br /> [[Category:Anatomy]]<br /> {{anatomy-stub}}</div>
