It was his research on natural selection during that voyage that formed the basis of his later work. He felt that natural and observable causes should be used to explain things that happen in nature. Darwin was able to observe many of these natural phenomenons, like earthquakes, erosion, volcanoes, and such.

What is Darwin's theory of natural selection?

Darwin's Theory of Evolution by Natural Selection
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.

What were Darwin's observations?

Darwin's observations that led to his theory of natural selection are: Overproduction - all species will produce more offspring than will survive to adulthood. Variation - there are variations between members of the same species. Adaptation - traits that increase suitability to a species' environment will be passed on.

What animals did Charles Darwin discover in the Galapagos Islands?
