- Prebiotic synthesis from CO atmospheres: Implications for the origins of life

Conclusions 

A CO-dominant atmosphere may have existed when life originated. This atmosphere could have produced a variety of bioorganic compounds with yields comparable to those obtained from a strongly reducing atmosphere. A small amount of CO₂ could have allowed the primitive Earth to freeze. This could mean that CO would have been more stable in the atmosphere than previously thought because of the reduced vapor pressure of water. Methane and ammonia would have been also more stable and could have contributed to the synthesis of bioorganic compounds. CO₂ is likely to have been present, but it might not have been significantly involved in the synthesis of bioorganic compounds.
