Say what you will about Texas, it appears their state board of education has got some backbone:

The State Board of Education voted Thursday to approve biology textbooks, despite criticism from religious activists who say the books as written fail to present the anti-evolution point of view.

I'm sure there will be a few people who read this and want to say something along the lines of, "but it is just a theory" or "don't you know there are serious problems with evolution?" or "alternatives deserve equal time." To them I would direct first to the talk.origins archive, probably the best introduction to biological science ever created. Trust me, your question or caveat is answered in there, better and more clearly than I ever could here.
