Again, microevolution, not macro.<quoted text>
The theory of evolution has proved itself in practice. It has useful applications in epidemiology, pest control, drug discovery, and other areas (Bull and Wichman 2001; Eisen and Wu 2002; Searls 2003).
Besides the theory, there is the fact of evolution, the observation that life has changed greatly over time. The fact of evolution was recognized even before Darwin's theory. The theory of evolution explains the fact.
Also, again, intellectual and scientific honesty should necessitate the presentation of the holes in evolutionary theory. I would also state that it should necessitate the teaching of an alternative theory that has it's basis in science as well. Teach both - the pros and cons.
