Evolution explains design without a designer.
The objection, in full
Paley's watch was the strongest pre-Darwinian argument. Darwin disposed of it. Random mutation plus non-random selection produces the appearance of design from below. We don't need a designer for the eye, the hand, or the human.
Biology is the study of complicated things that give the appearance of having been designed for a purpose.
or, in plain terms —Evolution killed God.
I have spoken to Brother Wolf and Sister Moon.
You give me a mechanism and call it an explanation. But the mechanism is itself a wonder. Selection requires reproduction; reproduction requires a self that can fail; a self that can fail is already a marvel.
Praised be my Lord with all his creatures, especially Sir Brother Sun, who is the day, through whom Thou givest us light. Whether by six days or six billion years, the Canticle is unchanged.
Evolution does not subtract praise. It tells us by how many means God brings the daisy out of the dust.
