I think I am much like you. Being a mechanical engineering student, I have been trained to look for holes in theories. That's how you prove things in the science world, test the theory until you know it is true. This can make studying the gospel very hard because instead of looking for truth, you are looking for lies to prove it is true. Not a very intuitive approach when doctrine can't be seen like other things in this world. But I also realize that science isn't as perfect as we think, or would like it to be. At one time, science spoke of a medium light could pass through called the aether. Luminiferous aether - Wikipedia, the free encyclopedia This wasn't that long ago when science seriously considered this mystical thing. I think when it comes to the relationship between faith and science, it shouldn't have to be "I believe in such and such even though science proves otherwise," but rather "I believe that the day will come when science will understand truth and my faith and science will be one and the same." I don't know much about DNA, but I do know that we don't understand as much about it as we think we do. P-Worm
