The first living organisms evolved in a reducing environment which had little free oxygen. Then, photosyntheitic prokaryotes arose and began "poisoning" Earth with free oxygen. This event is written in the geology of this planet, and had a profound effect on the evolution of living things. How did this chemical revolution affect early life? What innovations were made possible? What happened to those first, anaerobic organisms? Where are they found today? What does that say about the primordial earth?
