Answer:
NATURAL SELECTION:
Natural selection is a process whereby species which have traits that enable them to adapt in an environment survive and reproduce, passing on their genes to the next generation.
EVOLUTION:Evolution is a process of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their characteristics.
GEOGRAPHICAL ISOLATION: Geographical Isolation is the separation of two population by a physical barriers.It is a form of reproductive Isolation.
SPECIATION:
Speciation means formation of new species from the pre existing ones.New species are mainly developed due to isolation and variation.
HEREDITY:
Heredity is the transmission of genetic characters from one generation to the next generation.
VARIATION:
Variation are the differences in the combination of traits among members of species. These are slight changes occurred in chromosomes due to error in DNA copying.
GENETICS:Genetics is the branch of science which deals with the study of genes
