The complexity of life can be explained by natural selection from "summary" of The God Delusion - by Richard Dawkins by Instaread
The complexity of life, Dawkins argues, can be fully understood through the lens of natural selection. This theory, first proposed by Charles Darwin, explains how the vast diversity of life forms on Earth can be attributed to the process of evolution. Natural selection is a simple yet elegant concept that relies on three key components: variation, inheritance, and differential reproductive success. Variation refers to the differences that exist within a population of organisms. These variations can be seen in traits such as size, color, or behavior. Inheritance ensures that these variations are passed on from one generation to the next. This means that offspring will inherit certain traits from their parents. Differential reproductive success is perhaps the most crucial aspect of natural selection. This principle states that individuals with traits that are bet...
