The Strength of Darwin's Theory

 

It explained data better than previous explanations

            Variation

            Lack of perfection

            Developmental similarities

            Not all similarities the same

                        Homologous vs analogous similarities

            Sexual dimorphisms

 

It also makes specific, testable predictions

            All life should have some elements in common

            Species should exhibit differing degrees of similarity

            Should never see a "frog/mushroom"

 

We have tested the predictions from evolution for well over a century

            The pattern is clear.

            Life looks as if all species are related
