The Mariana Trench is the deepest point on Earth

Chinese scientists have decoded the genomes of finfish that live in the deepest seas in the Mariana Trench of the world to withstand hundreds of times higher pressure and no light at all, because their bodies are genetic at the genetic level in a relatively short period of time. It has gone through many dangerous changes. Research shows that many creatures live and breed in this abyss. In the early 1950s, the Soviet ship "Vityaz" and the Danish ship "Galati" studied deep trenches (many of which were discovered) and by far the deepest place on the planet is the Abyss Challenger in the Mariana Trench. The information belongs to the expedition team. More than half a century ago.In 1960, the Swiss submarine Trieste landed on the bottom of the Challenger Cliff for the first time.Submarine captain and oceanographer Jean Picard described the incident as follows: Below us is a shape similar to a flat fish, resembling a European red-brown fish, like two round eyes moving along the bottom, surrounded by mucus and waterdisappearing at night. Scientists immediately doubted this, especially since there were no cameras on the submarine, but reporters admired the image of the "Triestfish" and had been talking about it to the public for decades until some of the professors were misled. Thanks to director James Cameron's plan, the legend of Oblate appeared again in 2012. This is the third person in the world to see the bottom of Challenger Abyss from a deep Cameron, like the participants of the previous campaign, did not notice the flounder there, the Japanese who set traps at the bottom of the Mariana Trench, the Americans and the Chinese did not find her, and the assistant of Trieste did not speak about her confidently.In an article in 2012, British oceanographer Alan Jamison of the University of Aberdeen finally refuted the myth of "flounder Trieste": First of all, people know a real fish, for example, rays or European veins live in shallow water; And second, a deep submarine is unlikely to land directlysubmarine.According to fishery statistics, in fishes, the average arrival time of the first fish increases with increasing depth, reaching ten hours, that is, about 11 kilometers. Trieste stayed at the bottom for 20 minutes without bait traps. The main argument is the strong pressure, which seems to make it impossible for fish to live at depthsof more than 8.5 kilometers, but for being at these depths, the human body needs to make massive hanges. For a long time, it was believed that the finfish could live in the deepest place, and they were found at a depth of six kilometers. But he asked Among them is Jamison too, according to fish records,

there are 17 specimens of this type of Brucella, only two of which were captured at a very deep depth, so mistakes can be made, and no one has been found living in the deepest place. biological. Mechanically, Pseudomonas is the record holder, so, in 2013, Chinese researchers found it by testing a submarine deep at a depth of 7 kilometers. In 2017, Americans found it from 8178. Dozens of these fish were collected at a depth of meters This is a small fish, which measures 28 cm in length and weighs no more than 200 grams. They have transparent skin covered with mucus, and the internal organs through which two small, black eyes appear. It is completely blind and unresponsive to lighting traps. There is growing evidence that the human body has to be specially adapted to live deeper in the cold without light. The latest research on the genome allows scientists to unveil secrets here. For example, it turns out that as fish bony tissues deepen, the content of trimethylamine oxide - a simple organic compound that helps cells not to deform and respond to external pressure. These substances are called osmotic substances. There is also evidence that cell proteins lose their shape due to elevated pressure, which is fatal to living organisms. So there must be a mechanism that does not allow this. Therefore, there is a hypothesis about whether the sol-the sol retains the protein form or that soluble materials may agglomerate after their destruction.
