It takes planning and anticipatory design to construct a machine. This is the insight that is proving most challenging to Darwin’s theory of evolution by natural selection (TENS).
Suppose, for example, you need a gear to make an engine work. Nature could, presumably, evolve a gear. But would any evolved gear be the right diameter, with the right number of teeth, and a right-sized, properly centered axle hole? Would it even materialize at the location where it is needed?
TENS is popular, I believe, because people use it as an excuse to deny the possibility of a “God principle” in the natural world. The irony is that science seems headed in the opposite direction.
