Final answer:
Adaptation is the process by which living organisms develop traits that help them survive and reproduce. It is closely related to natural selection, which acts on the variations in a population to favor those with beneficial adaptations.
Step-by-step explanation:
Adaptation refers to the process by which living organisms develop traits that help them survive and reproduce in their environment. This can include physical structures, behaviors, or physiological processes.
Adaptation is closely related to natural selection, which is the mechanism by which individuals with beneficial adaptations are more likely to survive and pass on their traits to future generations. Natural selection acts on the variations in a population, allowing those with advantageous adaptations to have a higher chance of reproductive success.
