Submarine hydrothermal vents are the only comtemporary geological environment which may be called truly primeval; they continue to be a major source of gases and dissolved elements to the modern ocean as they were to the Archean ocean. Then, as now, they encompassed a multiplicity of physical and chemical gradients as a direct result of interactions between extensive hydrothermal activity in the Earth's crust and the overlying oceanic and atmospheric environments. We have proposed that these… Expand

A Hydrothermal-Sedimentary Context for the Origin of Life
TLDR
This work document constant permeation of the porous, carbonaceous, and reactive sedimentary layer by hydrothermal fluids emanating from the crust, representing a widespread system of miniature chemical reactors in which the production and complexification of prebiotic molecules could have led to the origin of life.

Bacterial Communities from Deep Hydrothermal Systems: The Southern Gulf of California as an Example of Primeval Environments
Deep hydrothermal systems result from the magmatic and tectonic activity of the ocean floor. This deep extreme biosphere represents a unique oasis of life driven by sulfur-based chemosynthesis… Expand
Transition metal isotope fractionation in marine hydrothermal deposits of the Mohns Ridge, North Atlantic Ocean
Seafloor hydrothermal vent systems form along mid-ocean ridges in all of the Earth’s oceans. They have a major impact on the chemical exchange between the lithosphere and the hydrosphere, as vast… Expand
Temperature and salinity history of the Precambrian ocean: implications for the course of microbial evolution
Abstract The temperature and salinity histories of the oceans are major environmental variables relevant to the course of microbial evolution in the Precambrian, the “age of microbes”. Oxygen isotope… Expand
A symbiotic view of the origin of life at hydrothermal impact crater-lakes.

  • 2016
TLDR
A new symbiotic model for the origin of life at hydrothermal crater-lakes is proposed here, and it is suggested that RNA virus and prions may represent the evolutionary relics of the RNA/protein world that survived as parasites for billions of years. Expand
Can Life Begin on Enceladus? A Perspective from Hydrothermal Chemistry
TLDR
This paper compares the properties of two proposed sites for the origin of life on Earth—hydrothermal vents on the ocean floor and hydrothermal volcanic fields at the surface—and asks whether similar conditions could have fostered the originof life on Enceladus. Expand
Mapping metabolism onto the prebiotic organic chemistry of hydrothermal vents
  • R. Braakman
  • Chemistry, Medicine
  • Proceedings of the National Academy of Sciences
  • 2013
TLDR
A unique experimental instrument is developed to systematically explore simulated hydrothermal vent chemistry, focusing on the chemistry of pyruvate, which has both a central role in modern metabolism and was plausibly formed prebiotically at hydroThermal vents. Expand
Organisms of deep sea hydrothermal vents as a source for studying adaptation and evolution
TLDR
This review describes some current research concerning metabolic and plausible genetic adaptations of organisms in a deep sea environment, usingiftia pachyptila as model. Expand
Hydrothermal simulation experiments as a tool for studies of the origin of life on Earth and other terrestrial planets: a review.
TLDR
This article critically reviews some of the organic synthesis and stability experiments that have been conducted under simulated submarine hydrothermal conditions and discusses the theoretical and practical considerations that apply to hydroThermal laboratory studies of organic molecules related to the origin of life on Earth and probably also to the other terrestrial planets.
