Intelligent Design (ID) has gained much publicity over the last few years with some public school boards proposing the mention of Intelligent Design as an alternative to the theory of evolution. The proponents of Intelligent Design hold that certain features of the universe and of living things can best be explained by an intelligent cause and not by an undirected process such as natural selection. We discuss the beginnings and the principles of the Intelligent Design movement and how Intelligent Design differs from the theory of Evolution, as well as from Creationism. Phenomena can be explained by the principles of either chance, necessity or design. We describe a process for testing for design and explain use of the the terms "irreducible complexity" and "specified complexity" used by ID proponents. We will also touch on some of the perceived strengths and weaknesses of the Intelligent Design movement.
