I'd guess most research is aimed at understanding something we know to be true but not necessarily why it is true.

Your 'knowledge' as to the truth of evolution is really based on a considerable amount of faith. You believe evolution is true, but you do not know why it is true. If fact, it may not be true at all. sounds like a religion to me. Of course, I am obviously referring to macro-evolution.

It's based on the "faith" that evidence means something. We have lots of evidence.

Sure we know why. It's called natural selection.
