Irreducible complexity
From PhiloWiki
Complex structures exist in nature. The challenge for evolution is how complex and useful mechanisms came about by pure chance, against all odds, in a chaotic and randomly evolving universe. Is life full of irreducible complexity that cannot arise through evolution?
- How did DNA evolve naturally?
- How could the complex cell have evolved?
- How could the eye have evolved?

Complex biological systems could not have evolved naturally

Complex biological systems could have evolved naturally
- But what if the designer did not style each species individually? What if he/she/it merely fashioned the primal cell and then let evolution produce the rest, kinks and all? That is what the biologist and intelligent-design proponent Michael J. Behe has suggested. Behe says that the little protein machines in the cell are too sophisticated to have arisen by mutation -- an opinion that his scientific peers overwhelmingly do not share. Whether or not he is correct, his version of intelligent design implies a curious sort of designer, one who seeded the earth with elaborately contrived protein structures and then absconded, leaving the rest to blind chance.

- The cell and several of its fundamental components and biochemical pathways are, according to Behe, irreducibly complex.
- The problem with this statement is that it is at least partially contradicted by the available literature on comparative studies in microbiology and molecular biology, which Behe conveniently ignores.

- Natural selection is not 'random' nor does it operate by 'chance.' Natural selection preserves the gains and eradicates the mistakes.
