Interdisciplinary review separating Earth's uncertain habitability boundary from the approximately 3.7 Ga sampled biosignature boundary; neither boundary is presented as an exact origin-of-life date.
Claim ledger
fossil-range · mediumThe 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.
