What did Charles Darwin discover that was so significant?
Charles Darwin changed the way people look at living things. Darwin’s Theory of Evolution by Natural Selection ties together all of the life sciences and explains where living things came from and how they adapt. Only certain members of a species reproduce, by natural selection, and pass along their characteristics.
Is the process in which the organisms that are best able to adapt?
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
What process did Darwin’s book suggest that organisms evolve through?
