Oh my gosh, how so simple an argument ends the debate.
irreducible complexity
checkmate darwin...
Intricate cellular components are often cited as evidence of intelligent design. They couldnt have evolved, I.D. proponents say, because they cant be broken down into smaller, simpler functional parts. They are irreducibly complex, so they must have been intentionally designed, as is, by an intelligent entity.
But new research comparing mitochondria, which provide energy to animal cells, with their bacterial relatives, shows that the necessary pieces for one particular cellular machine exactly the sort of structure thats supposed to prove intelligent design were lying around long ago. It was simply a matter of time before they came together into a more complex entity.
