There is a common misconception that evolution by means of natural selection is a random process ...
Darwin was not wrong, Creationists are:
Logic should lead you to conclude that mutations that are beneficial are of course going to survive, because those gene pools with useful mutations are a better candidate for reproduction: they are naturally selected.
This visual demonstration makes clear the difference between randomly selected genes and darwinian evolution of a gene pool.
The box with a blue border uses the principles of darwinian evolution, the box with a red border is the Creationist idea of evolution; completely random.
The way evolution works is quite beautiful, and as an algorythm the most powerful thing in the universe, I hope this helps people to understand.
This experiment is based on an experiment conducted by Richard Dawkins in The Blind Watch Maker, all credit to him.
