In a broad sense, Geobiology is the use of information preserved in and by the biosphere to attack problems of importance for understanding the geological evolution of the Earth. The interaction of life with the earth works in two directions: life has had an enormous impact on the chemical and physical evolution of this planet, and in turn, global changes in the surface environment of the earth have left their imprint on the genetic and molecular systems which are part of every living thing. In the past, the thrust of geobiological work at Caltech (and elsewhere) has focused primarily on the first of these domains, the effect of life on earth; this work includes many of the isotopic, biogeochemical, and biomineral studies of Patterson, Epstein, Lowenstam & their students. Today, researchers in our division continue to study the geochemical signatures of life (examples include the discovery of magnetofossils, and the discovery that bacterial arsenate respiration can precipitate arsenic sulfides), but the approach taken to explore these problems has now expanded to include molecular genetics.
