It seems like there's a whole lot of nothing going on for the first 2 billion years. But what I think we miss is during that time, a lot of the complex biochemical and organic pathways were being developed--without which none of the other classifications of lifeforms would have appeared--and none of these bio pathways manifest themselves in the fossile record.
If we were somehow able to classify organisms biochemically instead of by their physical features, I wonder how different the picture would look?
