Complexity arising from simple beginnings from "summary" of On the Origin of Species By Means of Natural Selection by Charles Darwin
Darwin's theory of natural selection posits that all complex life forms we see today have arisen from much simpler beginnings. According to Darwin, this process of evolution occurs through the gradual accumulation of small, heritable variations over time. These variations, when advantageous to the organism in its environment, are more likely to be passed on to future generations, leading to the development of new traits and ultimately new species. In his exploration of the concept of complexity arising from simple beginnings, Darwin uses various examples from the natural world to illustrate his point. One such example is the evolution of the eye, which he describes as having originated from a simple light-sensitive spot in primitive organisms. Through countless generations of gradual modifications, this simple structure has evolved into the complex, highly specialized organs we see in modern organisms....
