Evidence from fluid inclusions for microbial methanogenesis in the early Archaean era
Abstract
Methanogenic microbes may be one of the most primitive organisms, although it is uncertain when methanogens first appeared on Earth. During the Archaean era (before 2.5 Gyr ago), methanogens may have been important in regulating climate, because they could have provided sufficient amounts of the greenhouse gas methane to mitigate a severely frozen condition that could have resulted from lower solar luminosity during these times. Nevertheless, no direct geological evidence has hitherto been available in support of the existence of methanogens in the Archaean period, although circumstantial evidence is available in the form of approximately 2.8-Gyr-old carbon-isotope-depleted kerogen. Here we report crushing extraction and carbon isotope analysis of methane-bearing fluid inclusions in approximately 3.5-Gyr-old hydrothermal precipitates from Pilbara craton, Australia. Our results indicate that the extracted fluids contain microbial methane with carbon isotopic compositions of less than -56 per thousand included within original precipitates. This provides the oldest evidence of methanogen (> 3.46 Gyr ago), pre-dating previous geochemical evidence by about 700 million years.

“First, O2 is a product of cyanobacterial photosynthesis, which was lacking [89] in the environment at the origin of the acetyl‐CoA pathway and methanogens > 3.5 billion years ago [65, 82].”

“Methane isotopes [65] provide the earliest evidence for life on Earth, tracing methanogenesis, hence the acetyl‐CoA pathway, hence an ancestral CoFeS (judging by the homology between bacterial and archaeal CoFeS), hence corrins, into rocks 3.8 billion years of age.”

“Isotope data trace the ultralight isotope signature of the acetyl‐CoA pathway [68] back to > 3.5 Ga [65, 66], consistent with the structural (Fig. 3) and phylogenetic (Fig. 5) evidence for the age of corrins.”

From Early bioenergetic evolution (2013) · cites this paper as [164]
In the citing paper
“With that in mind, dismal appear the prospects of getting branching patterns sorted out for prokaryotes, which have been around for 3.8 billion years or more [30,164], assuming that there are any real branches in that phylogeny to be recovered in the first place [225], and the goal probably pushes phylogenetics beyond its limits.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
