As a scientist that specializes in issues concerning evolution, I am open to alternative explanations that better explain data. At present, I've seen no better theory to explain the data I've reviewed in publications and collected myself in my laboratory. I'm open to a paradigm shift, but the fundamentals of evolutionary theory clearly have not yet been falsified.

From a philosophical perspective, intelligent design might be tenable as a belief if you hold that the mechanisms described by evolutionary theory were instantiated as part of this biological reality...but this is untestable and so cannot be addressed by evolutionary theory.
