When Charles Darwin first proposed natural selection as the mechanism of evolutionary change, he provided many different lines of reasoning. One of them was that he and other biologists had observed striking examples of suboptimal design in nature. If a creator-God was perfect and designed the world and everything in it according to His perfect plan, how could poor structure/function be explained? If we view the natural world as the product of evolutionary forces, however, imperfection is not so surprising. Rather, examples of poor design reveal interesting things about an organism’s evolutionary past, and that’s the thrust of my new book Human Errors.1
Because courts in the United States rightly determined that creationism is a religious doctrine, not a scientific one, its proponents changed their approach, practically overnight, restyling their position as the theory of “intelligent design,” or ID. By focusing on the seemingly scientific principle of “irreducible complexity” and only implying a vague, unnamed “designer,” supporters of ID claim it as a valid scientific theory, not a religious doctrine necessarily. Notwithstanding the fact that vanishingly few scientists support this theory and that neither were the courts fooled by the semantic shift, ID has become the dominant expression of creationism in the United States and is supported by around 40 percent of the population.2 Support for ID is strongly stratified by age, with only around 25 percent of those under age 30 in support, and is finally beginning to decline after years of holding steady.3
