A Chemical Taxonomy of Life Genomics and Proteomics

Carolus Linnaeus (1707-78) published his book Species Plantarum in 1753 and started the science of taxonomy of plants as well as animals. Linnaean taxonomy, which remains the basis of modern classification, relies upon structure (morphology) and function. The close relationship between horses and zebras is quite clear to any observer. On the other hand, a new observer (a scientist from another planet ) would almost 

Chemical taxonomy of dams based on DNA sequences, in contrast to taxonomy based on morphology (shell structure, information supplied by Dr. Robert Vrijenhoek). Calyptogena elongata is morpholo cdly similar to Calyptogena kilmeri, but its DNA is actually closer to that of a clam, Vesicomya gigas, of a different genus.
