Jason Rosenhouse, of Evolutionblog, a mathematician, defuses the Creationists’ attempts to use math to disprove evolution.
Probability Theory:
Claims of mathematical disproof of evolution typically make use of probability theory. The idea is to show that it so improbable that a given complex biological structure, such as the vertebrate eye, could have evolved gradually that it is effectively impossible for it to have done so. Frequently this argument will include actual calculations purporting to place the assertion on a rigorous mathematical footing.As a professional mathematician, I am well aware of how impressive such calculations can appear to people untrained in probability. Math is unique in its ability to bamboozle a lay audience, which helps explain why creationists find it so appealing. Happily, though, you do not need to slog through the details of such a calculation to know that it is not correct. Probability theory is a major branch of mathematics that finds countless applications in a variety of sciences, but it is not powerful enough to support the sweeping conclusions creationists are trying to draw. To understand why, let us consider the basic elements of the subject.
