      Design for Living

      By: Michael Behe

      Bethlehem, Pa. � IN the wake of the recent lawsuits over the teaching of Darwinian evolution,
      there has been a rush to debate the merits of the rival theory of intelligent design. As one of
      the scientists who have proposed design as an explanation for biological systems, I have found
      widespread confusion about what intelligent design is and what it is not.

      First, what it isn't: the theory of intelligent design is not a religiously based idea, even
      though devout people opposed to the teaching of evolution cite it in their arguments. For example,
      a critic recently caricatured intelligent design as the belief that if evolution occurred at all
      it could never be explained by Darwinian natural selection and could only have been directed at
      every stage by an omniscient creator. That's misleading. Intelligent design proponents do question
      whether random mutation and natural selection completely explain the deep structure of life. But
      they do not doubt that evolution occurred. And intelligent design itself says nothing about the
      religious concept of a creator.

      Rather, the contemporary argument for intelligent design is based on physical evidence and a
      straightforward application of logic. The argument for it consists of four linked claims. The
      first claim is uncontroversial: we can often recognize the effects of design in nature. For
      example, unintelligent physical forces like plate tectonics and erosion seem quite sufficient to
      account for the origin of the Rocky Mountains. Yet they are not enough to explain Mount Rushmore.

      Of course, we know who is responsible for Mount Rushmore, but even someone who had never heard of
      the monument could recognize it as designed. Which leads to the second claim of the intelligent
      design argument: the physical marks of design are visible in aspects of biology. This is
      uncontroversial, too. The 18th-century clergyman William Paley likened living things to a watch,
      arguing that the workings of both point to intelligent design. Modern Darwinists disagree with
      Paley that the perceived design is real, but they do agree that life overwhelms us with the
      appearance of design.

      For example, Francis Crick, co-discoverer of the structure of DNA, once wrote that biologists must
      constantly remind themselves that what they see was not designed but evolved. (Imagine a scientist
      repeating through clenched teeth: "It wasn't really designed. Not really.")

      The resemblance of parts of life to engineered mechanisms like a watch is enormously stronger than
      what Reverend Paley imagined. In the past 50 years modern science has shown that the cell, the
      very foundation of life, is run by machines made of molecules. There are little molecular trucks
      in the cell to ferry supplies, little outboard motors to push a cell through liquid.

      In 1998 an issue of the journal Cell was devoted to molecular machines, with articles like "The
      Cell as a Collection of Protein Machines" and "Mechanical Devices of the Spliceosome: Motors,
      Clocks, Springs and Things." Referring to his student days in the 1960's, Bruce Alberts, president
      of the National Academy of Sciences, wrote that "the chemistry that makes life possible is much
      more elaborate and sophisticated than anything we students had ever considered." In fact, Dr.
      Alberts remarked, the entire cell can be viewed as a factory with an elaborate network of
      interlocking assembly lines, each of which is composed of a set of large protein machines. He
      emphasized that the term machine was not some fuzzy analogy; it was meant literally.

      The next claim in the argument for design is that we have no good explanation for the foundation
      of life that doesn't involve intelligence. Here is where thoughtful people part company.
      Darwinists assert that their theory can explain the appearance of design in life as the result of
      random mutation and natural selection acting over immense stretches of time. Some scientists,
      however, think the Darwinists' confidence is unjustified. They note that although natural
      selection can explain some aspects of biology, there are no research studies indicating that
      Darwinian processes can make molecular machines of the complexity we find in the cell.

      Scientists skeptical of Darwinian claims include many who have no truck with ideas of intelligent
      design, like those who advocate an idea called complexity theory, which envisions life
      self-organizing in roughly the same way that a hurricane does, and ones who think organisms in
      some sense can design themselves.

      The fourth claim in the design argument is also controversial: in the absence of any convincing
      non-design explanation, we are justified in thinking that real intelligent design was involved in
      life. To evaluate this claim, it's important to keep in mind that it is the profound appearance of
      design in life that everyone is laboring to explain, not the appearance of natural selection or
      the appearance of self-organization.

      The strong appearance of design allows a disarmingly simple argument: if it looks, walks and
      quacks like a duck, then, absent compelling evidence to the contrary, we have warrant to conclude
      it's a duck. Design should not be overlooked simply because it's so obvious.

      Still, some critics claim that science by definition can't accept design, while others argue that
      science should keep looking for another explanation in case one is out there. But we can't settle
      questions about reality with definitions, nor does it seem useful to search relentlessly for a
      non-design explanation of Mount Rushmore. Besides, whatever special restrictions scientists adopt
      for themselves don't bind the public, which polls show, overwhelmingly, and sensibly, thinks that
      life was designed. And so do many scientists who see roles for both the messiness of evolution and
      the elegance of design.
