Evolution of life on Earth depended upon molecular interactions between simple organic and inorganic components to build the basic language of life.  This organic-inorganic interplay has sculpted the geosphere of present-day Earth and shaped Earth’s biosphere into complex ecosystems that continue to change over time.  As life evolved biomolecules became more complex allowing for organic-inorganic and organic-organic interactions that promoted such biological processes as the folding of a polypeptide into a functional enzyme, the formation of protein-protein complexes, and the creation of homo- and heterogeneous lipid membranes.  This allowed for the development of more and more complex organisms.  Over that past three billion years or so, nature has created a myriad of biomolecules capable of interacting with other molecules in complex and amazing fashions resulting in the incredibly diverse collection of organisms that we now find on Earth.
