The watchmaker analogy or watchmaker argument is a teleological argument, which by way of an analogy, states that design of creation (like a watch) implies a designer.
The analogy has played a prominent role in natural theology and the “argument from design,” where it was used to support arguments for the existence of God and for the intelligent design of the universe.
The most famous statement of the teleological argument using the watchmaker analogy was given by William Paley in his 1802 book Natural Theology or Evidences of the Existence and Attributes of the Deity.
The 1859 publication of Charles Darwin’s theory of natural selection put forward an explanation for complexity and adaptation, which reflects scientific consensus on
the origins of biological diversity, and provides a counter-argument to the watchmaker analogy: for example, evolutionary biologist Richard Dawkins referred to the
analogy in his 1986 book The Blind Watchmaker giving his explanation of evolution.
