The Lord shall laugh at him... Psalm 37:13
".....Darwin’s fascination with natural theologian William Paley. He 
was
deeply impressed by Paley’s argument that life demonstrates clear
evidence for design, pointing to an all-powerful Creator.
Paley famously compared the design of living structures to the
intricate complexity of a watch. Darwin mimicked Paley’s logic and style
in his own writings, but he replaced the Creator with natural
selection.
Famed paleontologist Stephen Jay Gould commented in The Structure of Evolutionary Theory:
I was struck by the correspondences between Paley’s and Darwin’s structure of argument (though Darwin, of course, inverts the explanation). Darwin did not exaggerate when stating to Lubbock that he had virtually committed Paley to memory. The style of Darwin’s arguments, his choice of examples, even his rhythms and words, must often reflect (perhaps unconsciously) his memory of Paley. p. 119." EN&V
