Alfred Russel Wallace was a contemporary of Charles Darwin and independently developed a theory of evolution by natural selection which he presented together with Darwin in a joint paper in 1858. Lamarck preceded Darwin and proposed a theory of evolution based on the inheritance of acquired characteristics, while Aristotle lived over 2000 years before Darwin and did not propose a theory of evolution. William Paley was a theologian who argued for the existence of a divine creator based on the apparent design in nature, which was a view opposed by Darwin's theory of natural selection.
