Hydrothermal vent

supported theories argue that life came to existence inside hydrothermal vents, hydrothermal impact crater-lakes, and terrestrial, anoxic geothermal vents; these theories claim that life originated inside Earth and this notion is well supported. The correct theory must be able account for the fact that life emerged roughly 3.8 billion years ago, the short time gap between the formation of oceans and the origin of life, and the chemical composition of modern day cells (Baross and Hoffman, 1985).…

The marine world is highly dependent on the activity of microbes in many different ways. Microbes in the ocean come in the form of autotrophs and heterotrophs and come in any of the three domains of Eukaryota, Archaea, and Bacteria. Members of these domains can range from all niches as producers at the bottom of the food change, critical gut microbes and decomposers. Arguably, somewhere these and more duties are most important is around the hydrothermal vents found at the bottom of the ocean.…

Galápagos Rift revealed hydrothermal vents, and along with it new and unknown creatures that somehow has survived in very harsh conditions. Hydrothermal vents are most commonly found along mid-oceanic ridges, such as the Mid-Atlantic Ridge and the Galápagos Rift. Seawater seeping deep into the Earth’s crust through fissures and cracks in the seafloor is heated by magma beneath the surface, causing the water to boil and rise back up to the surface. As it rises, the water dissolves and…

Earth began, the newest clue is the discovery of hydrothermal vents. These vents are deeply immersed in the oceans that harbour rich ecosystems, the energy source from mid-ocean-ridge volcanism. Additionally the vents can reach high temperatures up to 407C (Sander, 2011). and can reach temperatures up to 121°C (Martin et al., 2008). Many researchers’ theories pertaining to the origins of life stem from a series of specific chemical reactions, as well as Earth’s atmosphere, which might have…

Scientists today know mostly everything there is to know about life on prebiotic Earth approximately four billion years ago, yet, they still do not possess the answer as to how life came to be from inorganic matter. Many question how life could have risen from non-living materials and become as complex as it is. Nobody knows for certain how the transition from inorganic matter to life occurred, however, there are several theories made to explain this transition (i.e. Clay theory, Primordial Soup…

In reviewing others posts I didn’t see anyone do a post on the suggested example of thermal vents so I thought I would take a look into it. The full term describing this amazing underwater creation is “hydrothermal vents.” Basically these vents are hot springs produced from underwater volcanoes, kind of like geysers that form on land. These vents form where two plates pull apart and lava covers the sea floor forming an entirely new floor than what was previously there. These vents were first…

of volcanoes on the ocean floor vary in every way which only makes them more mysterious and fascinating. The first discovery of a hydrothermal vent was aboard a 3-person submersible named Alvin in 1977 at the Galapagos Rift (WHOI, 2004). This vent was a discovery of warm fluids mixing with cold ocean water rising from the ocean floor crust (WHOI, 2004). “In 1979, a second hydrothermal system was discovered along the East Pacific Rise” (WHOI,2004). This discovery was much hotter than the first…

organic molecules, but also for the formation of oligomers and polymers. The experiments involved in testing the hypothesis was one that Stanley Miller did , in the experiment he mixed methane, ammonia, and hydrogen to form basic monomers. The reasoning the scientist gave to support their theory was the first cellular life forms may have evolved inside so-called black smokers at seafloor spreading zones, in the deep sea. Deep Sea Vent Hypothesis: The scientist involved in the hypothesis was…

After the discovery of hydrothermal vents, an alternative theory about origins of life have arisen, from new evidence found from these vents, that early life could have begun from hydrothermal vents. It has been theorised that the first organisms on earth had been autotrophs and were able to synthesise organic compounds from inorganic material in the surrounding environment (Morowitz et al. 2000). In the ecosystems surrounding these hydrothermal vents, the organisms living within these…

A deep-sea hydrothermal vent is one of the harshest places to live on earth. This is due to the pitch darkness, heavy metals, extreme acidity, poison gas and the enormous pressure. Sunlight penetrates no further than a few hundred feet down which means the deep-sea floor is as dark as a deep cave. There are no plants due to no sunlight and all the vent life belong to the animal kingdom. Due to there being no plants there is no photosynthesis. These organisms rely on a process called…
