Although he had minimal training in physics, chemistry, and mathematics, throughout his career Bateson consistently surprised doubters with his outstanding abilities. He was a firm evolutionist and believed that the forms on earth were descendants of a small number of ancestors. He made significant contributions to the science of genetics.
