Somewhat related to what Eric has done, I'm putting forward a challenge for evo sims. No prize offered, though.
I'd like someone to take either Animal Minimalis, or another bot that can beat Animal Minimalis in an F1 match, and evolve it. The number of mutations must be greater than or equal to the original DNA length of the bot. You "win" if your evolved version can beat the original in an F1 match.
To the best of my knowledge this has never been done. I had a sim going using Enitor Comesum, but the end result was significantly weaker than the original, despite what I thought were some strong selective pressures for combat.
