Having been raised in the JWs from early childhood, what I knew about evolution was what the WTS wanted us to know about it.
Once my faith in the WTS was shattered and I came to the realization (after many years) that I was an atheist, I felt that evolution was probably true, but I really didn't think about it too much until the last couple of years. My knowledge of it was still limited to what the WTS taught about it, and when I realized that I figured that I owed it to myself to go to reliable sources for information about the process of evolution. I'm so glad that I did, because not only did it prove, yet again, that the WTS completely misleads people regarding the teachings of evolution, but I learned about the scientific evidence for evolution and the various means that are used to date fossils, locate them and predict what fossilized remains should look like for given time periods and rock formations.
I still have a lot to learn, but I have far more confidence in the evidence for evolution than I ever did for any so-called prophecy that the WTS attempted to explain.
