Irreducible Complexity

Misconception 4: Life Forms evolve incrementally from very simple to more complex

Cause-effect patterns have to exist to explain everything because if everything in the universe is the product of randomness, science would be impossible. ~Einstein

If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find out no such case.” Charles Darwin [1]

This is describing what is known as “Irreducible Complexity” If a life form has separate functions that cannot be separated without causing the organism to stop functioning, then evolution could not explain it.

The Bombardier Beetle was once used as primae facie evidence of irreducible complexity but it has since been ruled out. The beetle mixes two caustic chemicals together and squirts its would-be predators with a bomb. The chemicals are stored in the body separately and mixed together when ejected to make an explosion that can kill attacking insects and injure small animals.

Bacterial Flagellum (Photo, below, courtesy Access Research Network) are now hands-down the masters of irreducible complexity http://en.wikipedia.org/wiki/Bacteria Inside the bacteria is a little motor that spins what looks like a tail to propel the bacteria from place to place. Like an electric motor, it has a stator, a rotor, bushings and more. No way could the little motor evolve piece-by-piece and be functional. The bacteria would starve. http://www.arn.org/docs/mm/flag_labels.htm The flagellum has been said to be the most efficient machine known to man. Immeasurably more efficient than man can design.

Bacterial Flagellum could never have evolved piece by piece and still function
