"For all of those who do see the overwhelming evidence of natural selection and life's descent from ancestors, and the immense span of time over which the story of life has unfolded, it is, to put it mildly, baffling how so many still do not. It is absolutely astonishing and often infuriating that some take it so far as to deny the immense foundation of evidence and to slander all the human achievement that foundation represents. With the facts on evolution's side, how can this doubt and denial persist, or even be growing, here at the outset of the twenty-first century?"                                           Sean B.
