Evidence for early life in Earth's oldest hydrothermal vent precipitates

evidence

Supports the report of haematite filaments in Nuvvuagittuq jasper and the at-least-3.77 Ga and possibly 4.28 Ga age range of the host rocks. Both the biogenicity and the age are disputed in the subsequent literature, which is not cited here. 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. Volume and page range are quoted from standing knowledge and were 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.
