The Trinity of Life: The Genome, the Proteome, and the Mineral Chemical Elements

R. J. P. Williams and J. J. R. Fraústo da Silva

Abstract: In this article the major changes in evolution from the simplest prokaryote cells to man and his industrial activity are described as a progressive change in the organization of chemistry in spatial compartments. The changes reflect the changing availability of chemical elements, produced first through the unavoidable production of oxygen by organisms and most recently through man's exploitation of the environment. We assume that initially Earth had a reducing environment from which it was necessary for organisms to obtain 20 chemical elements in simple cells.
