Sentences with phrase «living around hydrothermal vents»

The unusual changes in currents may help explain how the larvae of the heat - loving creatures living around hydrothermal vents are dispersed through long stretches of near - freezing waters to reach other warm havens, says Adams.

Not exact matches

Other researchers, however, say that the fossil stromatolites were not formed by living organisms, but by physical and chemical processes around hydrothermal vents.

Suggestions of hydrothermal activity on Europa led researchers to speculate that life there could resemble ecosystems around hydrothermal vents on Earth and would survive on chemosynthesis, extracting energy from chemicals.

A hotspot on the ocean floor could become a living laboratory where marine scientists can study underwater volcanoes and the weird life that clusters around the plumes of superheated water spurting from hydrothermal vents.

Although the evidence was subsequently contested, some single - celled microbial life lacking a nucleus that segregates their internal DNA or RNA («prokaryotes») from the surrounding cytoplasm may have flourished in darkness within cracks in Earth's seafloor crust and around deep, warm or boiling hot ocean springs (hydrothermal or volcanic vents, such as at Lost City or at black smokers) without a need for light or free oxygen in the oceans or atmosphere.

Mars is thought to have contained oceans with similar conditions to those near hydrothermal vents at around the same time the fossils were thriving, living creatures.

More recently, however, microbial life found around hydrothermal vent ecosystems (i.e., the «Lost City» found in the Mid-Atlantic Ridge, which is cooler than those found at «black smokers») indicate that Carbon - 13 is not selected against Carbon - 12 in hydrogen - rich environments where microbial life is starved of carbon, essentially in the form of carbon dioxide (Alexander S. Bradley, Scientific American, December 2009: pp. 62 - 67).

The revolutionary discovery in the 1970s of a thriving complex marine ecosystem around the hydrothermal vents of the Galapagos Rift on the ocean floor of the eastern Pacific forever changed our understanding of habitability showing that life could also arise and flourish in the complete absence of sunlight in conditions that were utterly toxic to any other life forms on Earth.

Astrobiologists theorize that, like ancient Earth, life may have emerged around hydrothermal vents located around the moon's submerged rocky core.

I think the various theories around hydrothermal vents are the best explanations for origin of life.

Geologists now know that the Gakkel Ridge is an active zone of slow spreading tectonic plates with massive amounts of activity including explosive emissions of super carbonated magma that have blown the tops off dozens of undersea mountains, produced mineral / metal riches from extensive hydrothermal vents throughout the range and holds sea life around smoker chimneys with abundant hydrogen - sulfide based ecosystems.
