Biomolecules contain tremendous amounts of information; this information is “written” and “read” through their chemical structures and functions. A change in the information of a biomolecule is a change in the physical properties of that molecule—a change in the molecule itself. It is impossible to separate the information contained in biomolecules from their structure and function. For molecules such as DNA and RNA, new information can be incorporated into the sequence of the molecules when that new sequence has favorable structural and functional properties. New biological information can arise by natural processes, mediated by the inter- actions between biomolecules and their environment, using the inherent relationship between structure and information. This fact has important implications for the generation of new biological information and thus the question of origins.
