Pecision helps to clarify what we mean. At least with GC, we can decide if it is really what we mean when we're talking about causality or not. > > <<if you do not approve trilobites, please feel free to pick ANY ancestors > of our exquisite human specie from - say - 1-2 billion years ago>> > 1-2 billion years ago, all life was unicellular. Even 500 million years ago, our ancestors were insipid worm-like creatures, contemporaneous with the earliest of trilobites, which were far more magnificent creatures.
