Since we've talked about creature with multiple heads, I would like to talk about multi-limbed creatures. And more precisely vertebrates with six or more limbs and centipedes-like creatures. How would their skeleton be like so that it is functional? And how many legs could a creature in Thrive could have? Would there be a limit?
I suppose, structurally, there'd be little difference from having four limbs, just more... Joint junctions to the vertebra. So more shoulder blades and pelvises.
Regarding a limit, I guess there wouldn't really be a magical law keeping anything from having "too many" limbs. The only limits would be whatever selective forces went against redundant limbs, or legs slowing each other down or taking up more energy than an organism with fewer legs doing just fine.
Unless the calculations going into the individual limbs cause too much lag, then there might have to be something. Can you imagine the resulting computer roast from armies of hexapedal centaurine aliens charging at each other?

My guess would be that arthropod ancestors had six limbs, but the fishes from which larger land animals hail had four main limbs. The reason for that is probably just a slight difference in hox genes, but there probably isn't too much advantage to one over the other in most survival cases.
