Integrated Multidisciplinary Detection of Martian Biosignatures: Carbon Chemistry, Isotopes, and Morphology

To the point

Finding life beyond Earth requires a holistic, multidisciplinary approach that combines carbon chemistry, isotopic and molecular biosignatures, morphology, and mineral clues within the planet’s environmental context, because abiotic processes like Miller-Urey can also produce organics and no single sign is definitive.
