The chemistry of evolution : the development of our ecosystem 1. The evolution of earth the geochemical partner of the global ecosystem (5 billion years of history) 2. Basic chemistry of the ecosystem 3. Energy order and disorder and organised systems 4. Outline of biological chemical principles : components pathways and controls 5. First steps in evolution of prokaryotes : anaerobic chemotypes four to three billion years ago 6. The evolution of protoaerobic and aerobic prokaryote chemotypes (three to two billion years ago) 7. Unicellular eukaryotes chemotypes (about one and a half billion years ago) 8. Multi cellular eukaryote chemotypes (from one billion years ago) 9. The evolution of chemotypes with nerves and a brain (0.5 billion years ago to today) 10. Evolution due to mankind : a completely novel chemotype (less than one hundred thousand years ago) 11. Conclusion : the inevitable factors in evolution
