The Evolution of Irreducible Systems
Irreducible complexity was coined by
Michael Behe in his book Darwins Black Box. The idea is that many biological systems
require several parts to function properly. Without all of the parts, the system does not
provide any selective advantage, and natural selection cannot preserve or optimize it.
Behe used a mousetrap to illustrate this concept in his book. The mousetrap does not
function properly if any of the pieces are missing. The drawback with the mousetrap
analogy is that it does not lend itself to a mathematical analysis.
The odds for opening the first
door are found as follows: this door requires 27 letters to be correct, and each letter
has a 1 in 20 chance of arising by chance. So the odds of finding the combinations are 1
in 2027 tries. The odds are actually slightly better. The 27 required letters
on this first door can be divided into 3 groups, and if the group associated with the
bottom floor is switched with the one on the top, then the door should still open because
all 3 infons still exist.
