A biosignature (sometimes called chemical fossil or molecular fossil) is any substance, such as an element, isotope, molecule, or phenomenon, that provides scientific evidence of past or present life on a planet.[1][2][3] Measurable attributes of life include complex physical or chemical structures, use of free energy, and the production of biomass and wastes. Biosignatures are central to the field of astrobiology and the search for extraterrestrial intelligence.
