I have been thoroughly trying to teach myself about the theory of evolution and the causes behind it. I learned in college that no mutations are beneficial. Even if they may seem beneficial on the surface, the mutation comes with one or more side-effect(s) that are disabling to the individual organism. Mutations also are not affected by environment so the possibility of having a "beneficial mutation" is practically impossible if possible at all.
With this possibility of mutation out of the way, I found myself searching for another cause of evolution. Because evolution states the we all were created from the same ancestor, this first organism must have held so much genetic information as to create many different sorts of offspring. But then I read in this website that DNA within organisms become more complex the further along we evolve. I understand that according to evolution, organisms become more and more complex, but if it were true that our DNA becomes more complex than going in an evolutionary reversal, our ancestor in the beginning must have been very basic, including its DNA. How could something so basic create such a wide-variety of organisms? How can DNA become so complex?
