Final answer:
Natural selection is a fundamental concept in biology that explains how organisms in a population develop traits that allow them to survive and reproduce.
Step-by-step explanation:
Natural selection is a fundamental concept in biology that explains how organisms in a population develop traits that allow them to survive and reproduce. It is the process by which traits that offer an advantage are more likely to be passed on to offspring, resulting in individuals with those traits having a better chance of survival. Natural selection is a driving force behind evolution, as it leads to the development of populations that are better adapted to their environments.
