Whether or not shi-tzus and mastiffs have micro-evolved from wolves (not a species change as they can still interbreed) does not seem to me to be proof of much of anything
When you look at those animals, is it such a stretch to think that man and other apes might share common ancestry just as different dog breeds do? Especially considering the overlapping DNA?
, in order for hearing to work, you need 3 "hearing bones" arranged just so, an eardrum held taught with the bones held in place against it just so, a way to transmit the vibration, a way to transform the vibrations into nerve symbols and a part of the brain to understand these electrical impulses.
So the issue is that you need to evolve many many complicated things all of which work together (if engineered just so) but which are useless by themselves. I'm not coming from the place others on this thread are, but you have to seriously violate occams razor to believe anything other than this was designed.
Firstly, though, Occam's Razor is not absolute. It does not state that the explanation with the fewest assumptions is always the right one. On the contrary. Secondly, if there is a watchmaker (or an earmaker), then we have to find out who made the watchmaker. And that sounds more complaticated than evolution. We have evolution plus
the guiding hand, as Mountaineer suggested, of an entity that started it all.

A recently discovered intermediate form is the primitive mammal Yanoconodon, from 125 million years ago in the Mesozoic, in which the ossicles have separated from the jaw and serve the hearing function in the middle ear, yet maintain a slender connection to the jaw via the ossified Meckel's cartilage, which in more advanced mammals dissolves during development.
