"A system performing a given basic function is irreducibly complex if it includes a set of well-matched, mutually interacting, non-arbitrarily individuated parts such that each part in the set is indispensable to maintaining the system's basic, and therefore original, function. The set of these indispensable parts is known as the irreducible core of the system. <ref>William Dembski, ''No Free Lunch'',(2001), p. 285. ISBN 0742512975</ref>

However, organisms that appear to have no unnecessary parts could have been built up from simpler parts that are no longer necessary.  Irreducible complexity has been used by astronomer [[Fred Hoyle]] and biochemistry professor [[Michael Behe]] to argue against the idea of "[[evolution through natural selection]]". Hoyle compares the probability of all the parts of a [[cell]] coming together through natural forces to the probability of a cyclone in a [[hangar]] assembling all the parts of a [[Boeing 747]] aircraft.
