Edward Humes Quotes

Natural selection may be unconscious but, as Darwin and his successors made clear, it is the opposite of a random force. It can drive changes in an organism in a very linear, per sis tent fashion—as had been observed in the laboratory, in nature, and in simulations such as the one that modeled eye evolution. Denton was wrong about evolution’s being one big lottery. The correct analogy would be a game of darts in which the players cannot see the target. Some darts will find their mark while the majority will miss—a random process. But the rules of the game eliminate all but the best-thrown darts. Because nature tosses an im mense number of darts—the mutation rate in any single gene in an organism will run in the millions—natural selection has plenty of well-targeted darts to choose from, and the march toward new and complex forms is not so difficult to understand, after all. But presenting an accurate meta phor would not have supported an attack on evolution.
