Abstract

Molecular biological markers, or biomarkers, are natural products that can be assigned to a particular biosynthetic origin. For environmental and geological studies, the most useful molecular biomarkers are organic compounds with high taxonomic specificity and potential for preservation. This chapter introduces some of the general principles, provides examples of their use for discerning the identities and physiologies of microbes in contemporary environments and summarizes biomarker research aimed at elucidating aspects of biological and environmental evolution in the Precambrian.
