Is Darwinian evolution an established fact, or a dogma ready to be overtaken by the next scientific revolution? The intelligent design movement argues the latter. Why Intelligent Design Fails assembles a team of physicists, biologists, computer scientists, mathematicians, and archaeologists to examine intelligent design from a scientific perspective. They consistently find grandiose claims without merit. Contributors take intelligent design's two most famous claims--irreducible complexity and information-based arguments--and show that neither challenges Darwinian evolution. They also discuss thermodynamics and self-organization, the ways human design is actually identified in fields such as forensic archaeology, how research in machine intelligence indicates that intelligence itself is the product of chance and necessity, and cosmological fine-tuning arguments. Intelligent design turns out to be a scientific mistake, but also a useful contrast highlighting the amazing power of Darwinian thinking and the wonders of a complex world without design.
