Not until Mendel’s rediscovered“ genetics” met Darwin’s natural selection in the “ modern synthesis” of the 1920s did science take a giant step toward understanding evolutionary mechanics. Charles Darwin developed the theory of how living things develop from simpler organisms over long periods of time. That theory is known as evolution through natural selection.
