"The Blind Watchmaker" is a book written by Richard Dawkins that explores the concept of evolution through natural selection. It argues against the idea of a designer by illustrating how complex biological structures can arise from simple, gradual changes over time. The title refers to the analogy of a watchmaker, suggesting that just as a watch requires a designer, some believe life does too. Dawkins uses various examples from nature to demonstrate how intricate features, like the eye or the wing of a bird, can evolve without a guiding hand. The book emphasizes the power of random mutations and natural selection in shaping life on Earth, promoting a scientific understanding of evolution.
