What would happen if we found something that radically challenged the now-accepted wisdom of evolution? In Darwin’s Black Box, Michael Behe argues that evidence of evolution’s limits has been right under our noses — but it is so small that we have only recently been able to see it. The field of biochemistry, begun when Watson and Crick discovered the double-helical shape of DNA, has unlocked the secrets of the cell. There, biochemists have unexpectedly discovered a world of Lilliputian complexity. As Behe engagingly demonstrates, using the examples of vision, bloodclotting, cellular transport, and more, the biochemical world comprises an arsenal of chemical machines, made up of finely calibrated, interdependent parts. For Darwinian evolution to be true, there must have been a series of mutations, each of which produced its own working machine, that led to the complexity we can now see. The more complex and interdependent each machine’s parts are shown to be, the harder it is to envision Darwin’s gradualistic paths. Behe surveys the professional science literature and shows that it is completely silent on the subject, stymied by the elegance of the foundation of life. Could it be that there is some greater force at work?
Michael Behe is not a creationist. He believes in the scientific method, and he does not look to religious dogma for answers to these questions. But he argues persuasively that biochemical machines must have been designed — either by God, or by some other higher intelligence.
