Evolution Questions

  When talking in class about evolution I thought of questions that evolution itself can't answer yet and may never be able to.  Why is the importance of our DNA similarities such great evidence when we have some of the same genetic make up of a banana?  Why do people not take into account natural disasters changing the layers of the earth when they consider the fossil record? How do we explain why we are the only bipedal creatures on the earth today if we are so much like so many other creatures? Some of these questions I don't think evolution can answer and that is where the questioning of evolution can easily take control.  The changes that we can see in microevolution are some of the only evidence we can see taking place today that can't be argued.  After learning about evolution I feel like I know more about it and the questions I have are more advanced research questions that I would never have had before.
