Evolution is a science.
In fact, Biology cannot presently be truly studied without incorporating evolution in almost every aspect of the endeavor. I'm sorry Mr. Carroll, but you've stepped on a pet peeve, here. Evolving an individual forward to its 'endpoint' is as silly as looking at a typewriter and a stack of paper and deducing the Foundation Trilogy. What happens over time is absolutely crucial. Technically, our evolution could take us right back to a creature indistinguishable from Australopithecus.
