Darwin's theory of evolution revolutionized biology from "summary" of Darwin's Dangerous Idea by Daniel C. Dennett
Darwin's theory of evolution was a revolutionary idea that completely transformed the field of biology. Before Darwin, the prevailing view of species was static and unchanging. It was believed that each species had been specially created by a divine force and remained unchanged since the beginning of time. However, Darwin's theory proposed a radically different explanation for the diversity of life on Earth. According to Darwin, species were not fixed entities but rather dynamic and constantly evolving populations. He argued that all living organisms are descended from a common ancestor through a process of natural selection. This process involves the gradual accumulation of small, heritable variations within a population over time. Individuals with traits that are better suited to their environment are more likely to survive and reproduce, passing on their advantageous traits to f...
