Often the assertion is made that evolutionary processes cannot create irreducibly complex features or that it cannot generate new "information." Perhaps some of you have seen some of the experiments in digital organisms where evolution can proceed at a pace quick enough for our human observations. One of these is Avida from Caltech. http://dllab.caltech.edu/avida/ Now this is not a perfect simulation, mind you. There are of course difficulties in modeling complex systems, such as life, so the program is a bit more simple than the real thing. But basically you give the sigital organism a starting point and let it evolve. You can download the program yourself and try it out. Many have. Most people have had very good success in modeling the evolutionary process using the program. Of course, some have found situations in which it does not work. But the program has shown how novel features, even irreducibly complex ones, can arise through random mutations and selection. Some of you might find the program and its result interesting. If you hunt around a bit, you can find many, many papers written from the research involved.
