I think that sim was a regular evo sim with a very low mutation rate. The base was a neural network like structure, where the basic survival actions where just some hand authored weights in the network.
I'll just post the best results I've managed to reach :
I managed to evolve a descent zero bot, capable of surviving in F1 conditions. It was a medium size shooter most of the way, but in the end it evolved into a very small shooter tieing to alge and slowly devouering them.
The mutation setting where probably too high, so it evolved a realy short genome. It may not look like much, but it gets some interesting behaviour out of it :
(Sim name is ZBotTied... I reinsert a bot now and then to adjust mutations and such, so I'm not sure about actual cycle count of the sim)

The latest I was running was some buggy bot I put together in a sim with a semi tough alge... It evolved into turning around itself as a better way of finding food, and moving backwards while shooting when encountering alies (It did have a conspec, but this was a good way to fight off canibots).
Along the way one cannibot did actualy evolve and survived, but it never whiped out the original species... so they basicaly coexisted (And I think they're still running a balanced eco system without destroying echother, but it's hard to tell because the colors got closer to eachother at one point...)
So I'm posting the latest sim and one from earlier where the difference was very clear. (Sim name is 0_0_0_Iflammaeater...)
And the one you mentioned is named NNNewBase... based on the NN thing...
