Organization Reveals Alien Life

A statistical test of molecular 'organization' (using ecological metrics of richness and evenness) can distinguish organic mixtures made by life from those produced abiotically. The method works on diverse datasets and remains sensitive even when samples are heavily degraded, so it can serve as a robust biosignature alongside chemical or isotopic evidence. — If adopted, this approach will change how scientists and agencies evaluate and report organic detections from Mars, meteorites, or exoplanet atmospheres, lowering false alarms and shaping mission priorities and public expectations.
