How are we sure that it constitutes and excellence? Is it even clear that in respect we do exceed the corals and the colonial jellyfish? With them, there are no internal barriers; information flow freely from unit to unit wherever it is needed. The unrestrictedness of the communication much exceeds that among people. Why does this fail to impress us?

The point cannot be just survival, nor even survival in numbers. Survival is just as well achieved by much less ambitions creatures which go in for sheer number. (In fact a cost-benefit-conscious gene that really understood its business would, no doubt, have remained on board something like the amoeba; it will probably be amoung the last to go.) Nor is it survival-as-society, since many animals achieve this despite a lot of bickering.
