WebSince hydrothermal vents were first discovered in 1977, scientists have identified over 300 animal species living at them. Ninety-five percent of these are unique to the vent environment, and thus were previously unknown. Some, like the tube worms, are not closely related to anything else. Why are vent animals so unlike those elsewhere? Web21 de jul. de 2024 · Yet recent studies have shown that two essential ingredients — amino acids and primitive cell membranes — can form spontaneously and reliably near the hydrothermal vents found in seafloors. The discoveries bolster a hypothesis about life’s origins that some scientists have supported for decades.
WebHydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards … WebHydrothermal vents are believed to have a role in the origin of life on Earth. Does this mean that we could find life inhabiting the oceans of Enceladus? Currently extremophiles have been found to inhabit the hydrothermal vents of our own oceans. So it is plausible that there may be the potential for life in hydrothermal vents at Enceladus.
