Chemical evolution and early Earth's and Mars' environmental conditions 1
Life originated more than 3.5 billion years ago either on Earth or on our neighbour planet Mars from where it reached Earth by lithopanspermia. Life’s origin was preceded by an abiotic chemical…

TLDR
The results highlighted here show that a variety of products can be formed in mildly reducing or even neutral atmospheres, demonstrating that contributions of atmospheric synthesis to the organic inventory on early Earth should not be discounted.
Organic Haze as a Biosignature in Anoxic Earth-like Atmospheres
TLDR
It is shown that organic haze formation requires methane fluxes consistent with estimated Earth-like biological production rates and detection of haze at an anomalously low CH4/CO2 ratio could suggest the influence of these biogenic sulfur gases and therefore imply biological activity on an exoplanet.

TLDR
A rise in O2 at approximately 2.4 Ga, and a concomitant decrease in CH4, provides a natural explanation for the Palaeoproterozoic glaciations.

Atmospheric carbon dioxide concentrations before 2.2 billion years ago
TLDR
The results suggest that either the Earth's early climate was much more sensitive to increases in pco2 than has been thought, or that one or more greenhouse gases other than CO2 contributed significantly to the atmosphere's radiative balance during the late Archaean and early Proterozoic eons.
The Paleoproterozoic snowball Earth: a climate disaster triggered by the evolution of oxygenic photosynthesis.
TLDR
It is argued that oxygenic cyanobacteria evolved and radiated shortly before the Makganyene snowball, and could have destroyed a methane greenhouse and triggered a snowball event on time-scales as short as 1 million years.
