Chapter 28: Science, Religion, and Teaching Evolution

A significant portion of human culture relies on belief systems that posit a designed universe established and maintained by an intelligent deity. However, the advancement of scientific thought, inaugurated by the astronomical findings of Copernicus and Galileo and the mechanistic physical laws formalized by Isaac Newton, progressively challenged the necessity of an active, intervening creator, eventually redefining the deity as a prime artisan who established self-functioning natural laws. Central to the theological defense of creation was the argument from design, most famously articulated by William Paley’s doctrine, exemplified by his renowned watchmaker analogy, which asserted that complexity in nature implies an intelligent designer. Charles Darwin’s theory of evolution by natural selection offered a complete, testable, and natural explanation for the origin, adaptation, and relationships of organisms, fundamentally providing a process of chance and necessity that replaced the need for supernatural design. This conceptual shift had a profound and widespread impact, revolutionizing not just biology, but also sociology, economics, politics, and philosophy by challenging the idea of fixed species and denying humanity a unique, specially created place in the cosmos. To illustrate the power of natural processes, the chapter examines the evolution of the eye, demonstrating how even extraordinarily complex light-gathering organs, such as those found in mollusks and vertebrates (indicating convergent evolution), can be explained through gradual, stepwise adaptation driven by selection. Historically, the conflict manifested in public confrontations, including the notable 1860 Oxford debate between Bishop Samuel Wilberforce and Thomas Huxley, and the internationally famous 1925 Scopes Monkey Trial featuring John Thomas Scopes, William Jennings Bryan, and Clarence Darrow. In contemporary society, this tension persists through fundamentalist movements that advocate for “creation science” and intelligent design. The chapter emphasizes the critical distinction that religious arguments possess explanatory power within belief systems but must not be confused with, or regarded as, scientific explanations, a legal reality confirmed by the 2005 Kitzmiller v. Dover decision.
