Detailed explanation-1: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-2: -Evolution. The process by which modern organisms have descended from ancient organisms over time. Common ancestor. An ancestor shared by two or more descendant species.

Detailed explanation-3: -More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.

Detailed explanation-4: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-5: -The environment creates selective pressure that is one of the driving factors in natural selection. Changes in the environment allow for some organisms to survive better than others within a species.
