ARTIFICIAL SELECTION. “One well-known computer program that purports to mimic evolution is the one by Richard Dawkins that creates “biomorphs”. The program generates stick figures that resemble insects, trees, bats, spiders, etc. The figures show a certain amount of variety as they evolve. But the evolution is by artificial selection, and nothing like gene duplication occurs. Instead, only nine or sixteen variables (in different versions) are allowed to wander within narrow ranges.”
