Organic chemistry in a CO2 rich early Earth atmosphere [PDF]
Earth and Planetary Science Letters, Elsevier, 2017, 479, pp.34-42, 2018 The emergence of life on the Earth has required a prior organic chemistry leading to the formation of prebiotic molecules. The origin and the evolution of the organic matter on the early Earth is not yet firmly understood. Several hypothesis, possibly complementary, are considered. They can be divided in two categories: endogenous and exogenous sources.
