We seem to have at least a couple of the types of selection, stabilizing and directional. The disruptive selection is where we're most lacking I think. The bots in even the most successful ecosims seem to stagnate into one particular "best" form, depending on enviroment and initial dna.
I'm going to try and see if walls can be modified to function as mobile blocks, creating a basic movable object for the bots to use/adapt to. I still need to make them(walls) stop being destroyed first though.
Sexrepro in one of my versions is working somewhat correctly now, seems to provide some novel effects.

This bit of reproductive code was conserved by one species during its evolution. Seems evolution likes the occasional re-mixing effects it brings.
Anyways it seems like we just need to provide more texture in a whole bunch of different areas. Just takes awhile to make it work.
