  • CHARLES DARWIN• Charles Darwin was greatly influenced by the geologist Adam Sedgwick and naturalist John Henslow in his development of the theory of natural selection, which was to become the foundation concept supporting the theory of evolution. Darwin’s theory holds that environmental effects lead to varying degrees of reproductive success in individuals and groups of organisms. Natural selection tends to promote adaptation in organisms when necessary for survival. This revolutionary theory was published in 1859 in Darwin’s now famous treatise On the Origin of Species by Means of Natural Selection.
