Mutations disprove the theory of upward evolution

Complex interrelated new features do evolve. It has been observed. One well known example is Richard Lenski's e-coli evolving the ability to metabolize citrates under oxygen rich conditions. Lenski's escherichia coli long term evolution experiment has been running for more than 50,000 generations now. Somewhere before generation 20,000 one of the populations involved in the experiment developed a neutral mutation. Somewhere around generation 30,000 this same population experienced another mutation which along with the previously mentioned one resulted in the ability to metabolize citrates under oxygen rich conditions. Lenski was able to reproduce these results by thawing earlier samples of his different populations. Once again the population with the original mutation developed the second mutation. The two mutations together resulted in an advantageous evolutionary change. Once again, you are wrong.

Even intelligent design proponent Michael Behe, one of a very few ID proponents with actual credentials in the feild, recognizes the mechanisms that allow these types of things to happen. He discusses them in his paper Experimental evolution, loss-of-function mutations, and “the first rule of adaptive evolution. In the paper he discusses three different types of changes that Functional Coded elemenTs (FCTs) can undergo. The changes include loss of function (the only thing you seem to be familiar with) modification of function and gain of function mutations. You can read the his paper here.
