Something that I think people in general have difficulty with also is the vast number of generations involved.

Humans have changed ALOT in the past 10,000 years. And humans have a relatively long generational change cycle at ~20 years.

Consider the changes wrought amoung our Canine Friends... (directed evolution to be sure, but significant changes in size, bone structure, coloring, coat, eye/nose sensitivity, etc) in 5 x 10^2 generations

A typical period of time in the Jurassic Age (covers around 55 million years if I recall) boils down to roughly 5 millions or so... Even with relatively long Generation gaps of 10 years, we are still left with 5 x 10^5 generations, or literally 1000 times greater than the above Dog example. (For example, if you would take the difference between a Pug and a Poodle, and expand that 1,000! times, thats a very significant difference... in very short geological time)
