Concealing and revealing coloration and their relation to natural selection

Roosevelt, Theodore, 1858-1919
Handwritten draft of Chapter 4 of Life Histories of African Game Animals . Theodore Roosevelt argues that followers of Charles Darwin have done a disservice to the theory of evolution by asserting the over-arching importance of natural selection in bringing about the evolution of species. The coloration of animals is one phenomenon often used to illustrate the importance of natural selection - i.e. the animals' color traits (striped, dark, light) help to conceal it from its predators and therefore enable it to survive. Roosevelt details his observations of African game animals to contest such theories, concluding that natural selection has played a minor part in developing the coloration of these animals.
