Evolution is not a person. It is an idea. It assumes certain things happened in a dynamic early earth, which was sometimes met with extreme changes, including, it is said, an asteroid impact. Basically, the proposal is that land animals, for example, develop this small change and it is supposedly passed along, and as these unguided, non-goal oriented changes accumulate, a particular type of animal not only improves its “fitness” to survive but can go from having gills to having lungs, from walking on land to becoming a whale. You see?

“Science fiction exists, however, in the context of many sciences. What you set forth on the theories about the beginning and the end of the world in Heisenberg, Schrödinger, etc. I would designate as science fiction in the best sense: they are visions and anticipations, by which we seek to attain a true knowledge, but in fact, they are only imaginations whereby we seek to draw near to the reality. Even within the theory of evolution, a great style of science fiction exists. Richard Dawkins’ selfish gene is a classic example of science fiction. The great Jacques Monod wrote sentences that he himself would certainly have inserted in his work just as science fiction. I quote: “The emergence of tetrapod vertebrates … derives its origin from the fact that a primitive fish ‘chose’ to go and explore the land, on which, however, he was unable to move except by hopping awkwardly and thus creating, as a result of behavioral modification, the selective pressure thanks to which the sturdy limbs of tetrapods would have developed. Among the descendants of this daring explorer, of this Magellan of evolution, some can run at a speed of more than 70 miles per hour …” (quoted according to the Italian edition Chance and Necessity, Milan 2001, p. 117ff) .”
