Summary
This chapter serves as an introduction to the book. It discusses the origin of Planet Earth and its Moon, their dependence on the Sun for energy, and the evolution of life on Earth. The evolution of the first living cell seems to have been a single event and all life on Earth is directly derived from this individual primary organism. The first life forms were anaerobic bacteria, but these later gave rise to photosynthesising cyanobacteria, which produced oxygen. The presence of oxygen eventually led to the emergence of aerobic animals and plants. The chapter then details the emergence of the oceans and supercontinents Pangea and Gondwanaland, the eventual break-up of the supercontinents and the development of the varied ecosystems which characterise Planet Earth at the present time.
