The nature of the last universal common ancestor and its impact on the early Earth system

evidence

Supports the c. 4.2 Ga age estimate for LUCA and the inferred genome size and metabolic character. Deliberately cited without volume or page numbers, which were not confirmed. V55 verification basis: this session had no network access to any source — WebFetch was egress-blocked and the WebSearch budget was exhausted — so the cited work was not retrieved and its pagination was not re-checked.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
