"My theory of evolution is that Darwin was adopted"

This quote by Steven Wright is a funny take on the theory of evolution. It implies that Charles Darwin, the scientist who proposed the theory of evolution, was embraced. This could be translated as a joke about how Darwin's theory of development is not accepted by everybody, which some people might not think it holds true. It might likewise be translated as a joke about how Darwin's theory of development is so widely accepted that it is practically as if he was embraced by the scientific neighborhood. In either case, the quote is a humorous way of satirizing the theory of development and its approval.
