If you have never noted the fact that they are predicated upon evolution as a fact, you haven't read them with any sort of care.

You don't believe that organisms evolved? That would make you a creo, wouldn't it?

If you have never noted the fact that they are predicated upon evolution as a fact, you haven't read them with any sort of care.

Have you read equivalent textbooks in other fields to see their treatment? It seems the only criticism we see here is of biology texts. I suspect that criticism is based more on religious sensitivity to the results of evolutionary theory than actual approaches in biology texts as opposed to other fields, but it has been a while since I perused them, so...

By the way, evolution is both a fact and a theory. The fact part is that each generation is slightly different from the one before it. The theory part seeks to explain these differences, and their effects through time.
