But the new evidence that humans have adapted rapidly and extensively suggests that natural selection must have other options for changing a trait besides waiting for the right mutation to show up.
Genetic algorithms mimic Darwinian natural selection, where "fitness" selects individuals for survival, breeding, and, hence, adaptive mutation.

It mimics Darwinian natural selection, making "fitness" (as determined by a formula applied to an individual) the chief selector of individuals for survival and procreation, together with mutation.
