Making do....

...with what you've got.
Evolution has to start with what has gone before--it can't "back up".

Much of our body is, if analyzed critically, really not very well "designed": the larynx is too small for its critical role in getting oxygen to the lungs; the coronary arteries are too narrow and few for their essential role in getting blood to heart muscle; our backs are too stiff and angled improperly for walking upright; our heads are too big; sinuses are laughable structures over all.
One feature that is an excellent example of "making do" is the synovial joint. Padded and packed and layered, filled with fluid, it still is incredibly vulnerable to environmental injury. But it's better than "bone grinding on bone"--but only just!
It's a good thing we have a large and fantastically plastic brain, which seems to have taken all the true creativity in its development--we need it to overcome our innumerable deficiencies!
