Detailed explanation-1: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. 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: -Natural selection is sometimes summed up as “survival of the fittest” because the “fittest” organisms-those most suited to their environment-are the ones that reproduce most successfully, and are most likely to pass on their traits to the next generation.
Detailed explanation-3: -The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution.
