Darwin's four postulates
For example, fossils show a gradual change from the aquatic fin to the terrestrial limb. Why was Darwin's and Wallace's theory of evolution by natural selection revolutionary? 1) It overturned the idea that species are static and unchanging. 2) It replaced typological thinking with population thinking.4. Describe Darwin’s four postulates for natural selection by filling in the summary table below. Postulate Description Overproduction Individuals of the same species have natural variations in their genetic traits. Some of these variations give an individual an advantage – increasing their chance of surviving and reproducing.
