Hydrothermal vents and the origin of life
Submarine hydrothermal vents are geochemically reactive habitats that harbour rich microbial communities. There are striking parallels between the chemistry of the H2–CO2 redox couple that is presentExpand
The emergence of life from iron monosulphide bubbles at a submarine hydrothermal redox and pH front
The hypothesis is that the FeS membrane, laced with nickel, acted as a semipermeable catalytic boundary between the two fluids, encouraging synthesis of organic anions by hydrogenation and carboxylation of hydrothermal organic primers, and led to the miniaturization of the metabolizing system.

On the origins of cells: a hypothesis for the evolutionary transitions from abiotic geochemistry to chemoautotrophic prokaryotes, and from prokaryotes to nucleated cells.

The universal ancestor the authors infer was not a free-living cell, but rather was confined to the naturally chemiosmotic, FeS compartments within which the synthesis of its constituents occurred, leading to the emergence of prokaryotic lineages from inorganic confines. Expand

Thermodynamic considerations related to formyl pterin synthesis suggest that the ability to harness a naturally pre-existing proton gradient at the vent–ocean interface via an ATPase is older than the able to generate a protongradient with chemistry that is specified by genes. Expand
The rocky roots of the acetyl-CoA pathway.
It is suggested that primordial biochemistry was housed in an acetate-producing hydrothermal reactor that retained reduced carbon compounds produced within its naturally forming inorganic confines. Expand
Serpentinization as a source of energy at the origin of life.
Hydrothermal mounds accumulating at similar sites in today's oceans offer conceptual and experimental models for the chemistry germane to the emergence of life, although the ubiquity of microbial communities at such sites in addition to the authors' oxygenated atmosphere preclude an exact analogy. Expand
Extreme accumulation of nucleotides in simulated hydrothermal pore systems
It is found that interlinked mineral pores in a thermal gradient provide a compelling high-concentration starting point for the molecular evolution of life, indicating that complicated active membrane transport is not required for the initial steps of life. Expand
Geodynamic and metabolic cycles in the Hadean
Abstract. High-degree melting of hot dry Hadean mantle at ocean ridges and plumes resulted in a crust about 30km thick, overlain in places by extensive and thick mafic volcanic plateaus. ContinentalExpand
Genesis of Vein Stockwork and Sedimentary Magnesite and Hydromagnesite Deposits in the Ultramafic Terranes of Southwestern Turkey: A Stable Isotope Study
Vein stockworks and lacustrine developments of cryptocrystalline magnesium carbonates of Neogene and Quaternary age occur within the partially serpentinized, discontinuous ultramafic belts ofExpand
The onset and early evolution of life
The tension between CO 2 dissolved at relatively high atmospheric pressure in the Hadean ocean, and H 2 generated as ocean water oxidized ferrous iron during convection in the oceanic crust, wasExpand
