Simple mechanisms select for certain tr
Simple mechanisms select for certain traits which have interesting side-effects. Multicellularity might evolve for one reason (clumping) but then that opens other possibilities and things move on from there.
There's a forthcoming paper that does something similar (not multicellularity though) in an artificial chemistry:
"Size selection and adaptive evolution in an artificial chemistry" Michael W. Lucht (2012) Artificial Life 18(2): 143-163.
