Self-refuting....I would have to say yes. It can be argued that humans and animals in general are "Intelligently Designed" because they can adapt to survive. The resiliency and adaptation can be linked to evolution. That word scares a lot of people, but animals in our surroundings evolve everyday with each passing generation. In must cases the next generation more apt to survival. For example, on a small scale, bacteria and viruses. New evolved strands are popping up everyday, mostly because of the over-use of antibiotics, but that's another thread altogether. But the point is, they actively evolve and become more and more resilient. That is the basis of evolution, and that is fact.
