complexity in an object guarantees the presence of intelligent design. Behe claims that there are instances of irreducible complexity in the natural world and that parts of the world must have been designed. This negative argument against step by step evolution ignores longstanding evidence that evolution proceeds through changes of function from preceding systems. The specific examples Behe proposes have been shown to have simpler homologues which could act as precursors with different functions. His arguments have been rebutted, both in general and in specific cases by numerous scientific papers. In response, Behe and others, "ironically, given the absence of any detail in their own explanation, complain that the proffered explanations lack sufficient detail to be empirically tested". Unreasonable effectiveness of mathematics William Lane Craig has proposed an nominalist argument influenced by the philosophy of mathematics. This argument revolves around the fact that, by using mathematical concepts, we can discover much about the natural world. For example, Craig writes, Peter Higgs, and any similar scientist, 'can sit down at his desk and, by pouring over mathematical equations, predict the existence of a fundamental particle which, thirty years later, after investing millions of dollars and thousands of man-hours, experimentalists are finally able to detect.' He names mathematics as the 'language of nature', and refutes two possible explanations for this. Firstly, he suggests, the idea that they are abstract entities brings about the question of their application. Secondly, he responds to the problem of whether they are merely useful fictions by suggesting that this asks why these fictions are so useful. Citing Eugene Wigner as an influence on his thought, he summarizes his argument as follows: "Third way" proposal University of Chicago geneticist James A. Shapiro, writing in the Boston Review, states that advancements in genetics and molecular biology, and "the growing realization that cells have molecular computing networks which process information about internal operations and about the external environment to make decisions controlling growth, movement, and differentiation", have implications for the teleological argument. Shapiro states that these "natural genetic engineering" systems, can produce radical reorganizations of the "genetic apparatus within a single cell generation". Shapiro suggests what he calls a 'Third Way'; a non-creationist, non-Darwinian type of evolution: In his book, Evolution: A View from the 21st Century, Shapiro refers to this concept of "natural genetic engineering", which he says, has proved troublesome, because many scientists feel that it supports the
