Evolutionary dynamics is the study of how a group of organisms change over time. It looks at how the environment and natural selection affect the way a species develops and passes on traits to its offspring. The process of evolution is driven by random changes called mutations that occur in an organism from generation to generation. Over time, some of these mutations will be passed on and become more common in the population. Natural selection is a process that helps certain traits to become more common than others by selecting the ones that help an organism survive and reproduce in its environment. Evolutionary dynamics looks at the long-term effects of these changes and how they shape the lives of species over time.
