13C-Depleted Carbon Microparticles in >3700-Ma Sea-Floor Sedimentary Rocks from West Greenland

evidence

Supports the carbon-isotope evidence for biological carbon fixation in more than 3.7 Ga Isua sediments. 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.
