Bots and Simulations > Evolution and Internet Sharing Sims
200 Hour Zerobot Sim
EricL:
Evolution requires differential survival tied to genetics. That is, there must be some implicit or explicit competition between individuals and genotypes which relates to reproductive fitness.
I suggest one such battle front - that of aquiring nrg. Bots that are better at aquiring nrg then others are fitter, which should lead to higher reproductive fitness. There are other battle fronts. I'm not saying that bots given free nrg will do nothing or fail to evolve. One can imagine them competing in other ways, say through metabolic effeciency in the face of costs. But personally, I prefer sims which select for increased complexity not increased simplicity. This is why I prefer not to have any costs at all in my evo sims these days and use shepards/preditors instead for applying selective pressure.

The problem lies not with food acquisition but with successful reproduction. A bot would have to evolve conspec first.

What exactly do you mean by this? Conspec recognition - indeed our whole concept of species - is artifical and means little in an asexually reproducing evosim population... Replication, yes of course and that is the main battle front and main determinant of fitness in all zerobot sims I know of. I.e. out replicating others. Replcaition is fairly easy to evolve, it happens in most zero bot sims after a few million cycles and invaribly is ultimatly limited by the body limit which is where nrg aquisition becomes the key element of compitition.
But conspec recognition? What does that even mean in an evo sim?

Maybe he means not eating your own the same cycle you reproduced?

You just don't see prediation of any form in zerobot sims. Eating another bot, be it your offspring or any other is a sophisticated act, one that requires conditional logic or at least a combination of mutliple coordinated actions. We havn't seen it evolve yet. It's just too sophisticated. Hopefully some day.
