One can say that Charles Lyell’s work greatly contributed to Darwin’s theory of evolution. Charles Lyell was a geologist and paleontologist who published Principles of Geography and he also theorized natural law. After reading Lyell’s publication Darwin was greatly influenced and was able to review thoroughly his findings during his voyage. Darwin first noticed shells embedded in a cliff along a shore line that were about 45 ft. above sea level. He also noticed that the line was not perfectly horizontal which indicated that it had moved. This would support Lyell’s theory of geological change over a great period of time. Without having read Charles Lyell’s publication Darwin might have not considered the adaption of species or natural law.
