What is one result of natural selection acting on a population?

One result of natural selection acting on a population is the gradual improvement of adaptations over time. Natural selection is a mechanism that favors individuals with traits that enhance survival and reproductive success in a given environment. Over generations, these advantageous traits become more common within the population, as individuals with these traits are more likely to survive, reproduce, and pass them on to their offspring. This process leads to a gradual evolutionary change where the population becomes better adapted to its environment.

In essence, as the environment changes or as organisms move to different habitats, natural selection can drive the development of new adaptations, enhancing the population's overall fitness. This ongoing process is fundamental to the evolution of species and contributes to the biodiversity we observe today.
