Yet, recent studies have highlighted possible preservation biosignatures carried some oldest carbons. Laboratory simulations increasingly being used better constrain transformations organic into induced sedimentation burial processes. These research advances justify a reevaluation putative biogenicity numerous carbons, including presumed traces on Earth.
