Variation and natural selection are fundamental concepts in the theory of evolution. Variation refers to the differences in traits among individuals within a population, which arise from mutations, genetic recombination, and other factors. These differences can affect an organism's ability to survive and reproduce in its environment. Natural selection is the process by which certain traits become more common in a population because they provide some advantage in terms of survival or reproduction. Over time, this process can lead to adaptation, where populations become better suited to their environments, and potentially give rise to new species .
