answered-by-expert Expert Answer
Evolution refers to the gradual development of organisms from a simple to a more complex form. It is through evolution that different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. It occurs slowly over time because of slight variations in the genes that one generation passes down to the next.
