The Life navigation envelope begins at 3.7 Ga as a conservative sampled biosignature boundary supported by biogenic-graphite evidence and extends to living Earth life at 0 Ma; 3.7 Ga is a minimum age by which life is evidenced, not a precise date for abiogenesis, LUCA or the origin of every lineage. This navigation entry is not a phylogeny or a complete taxon dossier.
