Richard Dawkins is the leading evolutionist and spokesperson for evolution today. In his famous book The Blind Watchmaker, he says:
“Biology is the study of complicated things that give the appearance of having been designed for a purpose.”
“Natural selection is the blind watchmaker, blind because it does not see ahead, does not plan consequences, has no purpose in view. Yet the living results of natural selection overwhelmingly impress us with the appearance of design as if by a master watchmaker, impress us with the illusion of design and planning.”
