"You can run an earth system without plants and without animals. But you can't do that without microbes. In fact, throughout much of earth's history, that's the way it was. It was photosynthetic bacteria and decomposing bacteria, and the earth functioned. Plants and animals are really quite recent innovations." --an ecologist.
Speaking of photosynthetic and decomposing bacteria I think my compost is almost ready. I am raging jealous of Rich's Project 5. I will have to visit him soon and gush.
Brains: a slightly less recent innovation.
