A Diversity-Based Biosignature: Statistical Organization of Molecular Assemblages Across Terrestrial and Extraterrestrial Contexts
To the point
Led by Gideon Yoffe, Fabian Klenner, Barak Sober, Yohai Kaspi, and Itay Halevy, the work shows a diversity-based biosignature in amino acids and fatty acids where biotic samples are more diverse than abiotic ones, a pattern robust to space-like degradation and detectable from relative abundances in data from current and planned planetary missions, with all data and code available on Zenodo.
