Final answer:
Natural selection is the process where organisms best adapted to their environment tend to survive and reproduce, passing their beneficial traits on to future generations, leading to adaptation.
Step-by-step explanation:
This process enables organisms with traits that are suited to their environment to produce more offspring, thereby passing their advantageous traits on to the next generation. Over many generations, these characteristics can lead to significant changes in a species, resulting in adaptation. Adaptations are heritable traits that aid the survival and reproduction of an organism, helping it to fit better into its environment. As environments change, natural selection drives the evolution of species, leading them to develop new adaptations.
