Selection is the process of choosing the best option from a set of alternatives. This can occur in various contexts, such as in hiring employees, picking a product, or making decisions in everyday life. The goal of selection is to identify the choice that best meets specific criteria or requirements. In biology, selection refers to the mechanism of natural selection, where certain traits become more common in a population over generations. This occurs because individuals with advantageous traits are more likely to survive and reproduce, passing those traits to their offspring. This process plays a crucial role in the evolution of species.
