Reader Ted sent along a rebuttal to that pathetic evolution “simulation” written by a creationist—it’s a much better simulation that was presented at TAM5, called IC Evolver. The simulation plays a simple game that has a strategy that can be encoded in strings, and it starts with a set of randomized strategies, which it then uses and modifies, generation after generation, to maximize the score. Two cool things about it: one is that it modifies the strategy with common genetic operations, like insertions, deletions, point mutations, and recombination, and displays them graphically so you can see what’s happening. Another is that it tests for irreducible complexity—when there are 5 components, and removing any one of them reduces the score it can get to 0, it flags it.
You can see the scores steadily improve, and you can also see irreducible complexity evolve.
Turn it loose and let it run in the background. It works fairly quickly.
