Detailed explanation-1: -If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
Detailed explanation-2: -What has to happen for an inherited trait to increase in a population? Organisms with the trait need to bear more offspring than organisms without the trait.
Detailed explanation-3: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.
Detailed explanation-4: -Evolution occurs by natural selection, the process by which organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Evolution is due to differences in the survival and reproduction of individuals within a population.
Detailed explanation-5: -Individuals with adaptive traits-traits that give them some advantage-are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population.
