WebDarwin and Wallace’s theory of evolution by natural selection can be summarized by four steps: 1. There is variation in some trait of interest. 2. Individuals with traits that best match their particular environment will on average leave more descendants than others, either because they have higher survival or higher reproductive output. 3.
