It can be straightforward to confuse facts and theories, but they remain distinct entities. Asserting that evolutoion by natural selection is not a fact does not diminish its significance as a theoretical framework. The theory is founded on empirical evidence and provides a deeper understanding of the subject matter.  Scientific theories evolve over time as new evidence and discoveries emerge. They continue to be refined and expanded as our knowledge of the natural world grows. Evolution Talk is also a book! You can find links to Amazon, Barnes & Noble and others on the front page of EvolutionTalk.com, or call your local bookstore and ask them to order a copy.
