There are people who openly suspect me, at least in an affable fashion, of having an undue obsession for evolution. But I do not claim, nay pretend, to possess an ounce of intelligible knowledge on the subject. Far from it. Being fanatical of anything is, I learn, the greatest stumbling block to the development of science. As the inimitable Carl Sagan once remarked, we should keep our mind open, but not too wide that our brains fall off.
