The chief mechanism of evolution is natural selection. Whilst I can't hang around long enough to see what elephants might evolve into next, I can see natural selection in action all around me. And, in the diversity of life and the inter-relationships of organisms on the levels of cell biology, biochemistry, anatomy, morphology, physiology and embryology (all of which were facets of my degree course many moons ago), I can see evolution.

Wacko, pete hasn't even read On The Origin Of Species (I won't be so unkind as to suggest that he can't read it. Yes I will).
