How do scientists account for the development of life on earth?. What is biological evolution by natural selection, and how can it account for the current diversity of organisms on the earth?. History of Evolution. The evolution of life is linked to the physical and chemical evolution of the earth.. Life on earth evolved in two phases over the past 4.7 -4.8 billion years. Chemical evolution (1 billion years) of the organic molecules and systems of chemical reactions needed to form the first proto-cells.. Section A: Software Basics. Section B: Office Suites.
