1 Theory of Evolution by Natural Selection
... It took Darwin years to form his theory of evolution by natural selection. His reasoning went like this: 1. Like Lamarck, Darwin assumed that species can change over time. The fossils he found helped convince him of that. 2. From Lyell, Darwin saw that Earth and its life were very old. Thus, there h ...
