I do not believe in pussy cats licking the faces of their kittens nor in children laughing and playing pranks. It is not necessary to believe in something which we can all see happening and which constantly manifests its own truth. Stripped of all misconceptions, evolution is like the growth of an oak or the laughter of a child. It is a natural phenomenon that is abundantly apparent to everyone who has an open eye and an open mind. Thousands of persons have observed it and used it to their advantage.
Evolution simply means change.
The growth of the oak and the laughter of the child are familiar examples of natural change that is going on around us at all times. Nature has no other phenomena that are more ubiquitous and easily observed than change. There are theories about how evolution works but these are not properly called the theory of evolution. The best known theories about how evolution works are those that were proposed by Charles Darwin. They are properly called the Theory of Natural Selection and the Theory of Sexual Selection.
