Molecular biologist Michael Behe described a system made of several interacting parts, whereby the removal of one part would disrupt the functioning of the whole, as irreducibly complex. Both creation scientists and intelligent design proponents highlight examples of irreducible complexity in their studies. The very structure of these systems--with their interdependent parts working all together or not at all--demands design, not chance. Nevertheless, a team of evolutionary molecular biologists think they may have refuted irreducible complexity. They recently studied the parts of a particular cellular machine involved in protein transport, claiming that it was actually reducible to its component parts...
