Energy yields for hydrogen cyanide and formaldehyde syntheses: The hcn and amino acid concentrations in the primitive ocean
These results are a model for atmospheric corona discharges, which are more abundant than lightning and different in character and allows a yearly production rate to be estimated. Expand
The Origin and Early Evolution of Life: Prebiotic Chemistry, the Pre-RNA World, and Time
The time for evolution of the first DNA/protein organisms to oscillatorian-like cyanobacteria is usually thought to be very long, but recent results on the organophosphate and phosphonate hydrolyzing phosphotriesterase from Pseudomonas diminuta and other soil eubacteria suggest that this new enzyme diverged by duplication from the α/β barrel family.

The Cold Origin of Life: A. Implications Based On The Hydrolytic Stabilities Of Hydrogen Cyanide And Formamide
It seems unlikely that HCN could have polymerized in a warm primitive ocean, and it is suggested that eutectic freezing mighthave been required to have concentrated HCN sufficiantly for it to polymerize. Expand
Reasons for the occurrence of the twenty coded protein amino acids
It is concluded that aspartic acid, glutamic acid, arginine, lysine, serine and possibly threonine are the best choices for acidic, basic and hydroxy amino acids. Expand
Prebiotic synthesis from CO atmospheres: Implications for the origins of life
It was shown that a CO-CO2-N2-H2O atmosphere can give a variety of bioorganic compounds with yields comparable to those obtained from a strongly reducing atmosphere, which might have been conducive to prebiotic synthesis and perhaps the origin of life. Expand
Hydrogen Consumption by Methanogens on the Early Earth
H2-consuming autotrophs are likely to have had a profound effect on the chemistry of the early atmosphere and to have been a dominant sink for H2 on the early Earth after life began rather than escape from the Earth's atmosphere to space. Expand
Submarine hot springs and the origin of life
The popular hypothesis that life arose in hydrothermal vents is examined, based on a number of misunderstandings concerning the organic chemistry involved, which would not allow synthesis of organic compounds but would decompose them, unless the exposure time at vent temperatures was short. Expand
