I see no science papers linked in the article. No hurry. When you find the scientific paper. Quote my reply and link it.
PS:- Everything the article you linked to is scientifically wrong. Its an absolutely proven fact that early earth did not have
any free oxygen in its atmosphere (all oxygen atoms were locked in CO2, H2O, SiO2 etc.).
The rise of atmospheric oxygen : Article : Nature
Excerpts
Two facts are known with certainty: Earth's earliest atmosphere was essentially devoid of oxygen; and today's atmosphere is composed of 21% oxygen.
A battery of geological indicators suggested a shift from an anoxic to an oxic atmosphere some time between 2.5 and 2.0 billion years ago. This shift is known as the great oxidation event
3.
The most compelling evidence was the absence in older stratigraphic units of 'red beds', sedimentary rocks stained red by iron oxide. Instead, an abundance of lithified ancient soils that had lost their iron during weathering were found, reflecting the absence of oxygen in the weathering environment.
The 'smoking gun' for the rise of atmospheric oxygen was discovered and reported in 2000 (ref.
4).
Rocks older than about 2.45 billion years contain a large degree of mass-independent fractionation (MIF) of sulphur isotopes; rocks younger than 2.32 billion years show essentially none5 (
Fig. 1)....The signature of MIF sulphur photochemistry is small and is rapidly homogenized in the modern oxidizing atmosphere.
By contrast, in an oxygen-free atmosphere, large MIF effects are preserved, resulting in contrasting isotopic compositions of reduced and oxidized sulphur species that are deposited from the atmosphere and incorporated into sedimentary rocks....To preserve the MIF signature, three conditions are needed:
very low atmospheric oxygen, sufficient sulphur gas in the atmosphere, and
substantial concentrations of reducing gases.
MIF disappears when oxygen levels reach 0.001% of the present atmospheric level (PAL)
8, and iron is retained in ancient lithified soils when oxygen is at 1% of its PAL.
More detailed analysis based on mountains of evidence on how oxygen concentration changed in the atmosphere and oceans over time.

Since I have a chemistry degree feel free to ask anything that is difficult to follow and I will attempt to explain it as best as I can.
