Molecular Biosignatures [PDF]

open access: possibleSpace Science Reviews, 2007
Life, as we know it, is based on carbon chemistry operating in an aqueous environment. Living organisms process chemicals, make copies of themselves, are autonomous and evolve in concert with the environment. All these characteristics are driven by, and operate through, carbon chemistry.
