Arguing that the perfection of the human body is the result of improbable mutation, a prominent Darwinian uses the metaphor of climbing a mountain to illustrate how natural perfection is due to the unending journey of DNA through time
The metaphor of Mount Improbable is represented in the combination of perfection and improbability, which is epitomized in the seemingly 'designed' perfection of living things. Dawkins skillfully guides the reader on a breathtaking journey through the mountain's passes and up its many peaks to demonstrate that following the improbable path to perfection takes time. Evocative illustrations accompany Dawkin's eloquent descriptions of natural perfections such as the teeming populations of figs, the intricate silken world of spiders, and the evolution of wings on the bodies of flightless animals. Through it all runs the thread of DNA, the molecule of life, responsible for its own destiny on an unending pilgrimage through time.
