The Darwinian Mechanism and the Evolution of Life

The critical claim of intelligent design is not that natural selection doesn't explain anything, but that it doesn't explain everything. A random mutation can break a gene and say cause a brown bear to lose its coloration and become a white polar bear. That's exactly right. If you posit that natural selection produced all of life, then it has to have produced not only trivia, but the profound molecular machines that are found in the cell. And we don't see that.
