Darwin proposed the theory of evolution by natural selection from "summary" of To Explain the World by Steven Weinberg
In the mid-nineteenth century, Charles Darwin put forth the groundbreaking idea that species evolve over time through a process known as natural selection. This theory revolutionized the way we think about the natural world and our place in it. Darwin's theory of evolution by natural selection challenged existing beliefs about the origins of species and provided a new framework for understanding the diversity of life on Earth. Darwin observed that within a population, there is variation in traits such as size, color, and behavior. He also noted that some of these variations are heritable, meaning they can be passed down from one generation to the next. Darwin proposed that individuals with advantageous traits are more likely to survive and reproduce, passing on these traits to their offspring. Over time, this process can lead to the accumulation of beneficial traits in a population, ultimatel...
