Scientists have explained the emergence of life on Earth

Researchers recreated the environment that existed on our planet before the emergence of organisms.
Scientists from the Institute of Promising Researchers in the United States, the Institute of Earth and Life Sciences in Japan, and the University of New South Wales in Australia were able to find out how life came about on Earth. The experimental results are published in the journal Proceedings of the National Academy of Sciences.

To find out how the first bacteria originated on our planet, the researchers created a mixture of sodium chloride, ammonia, phosphate and hydrogen cyanide, and then exposed it to high-energy gamma radiation. Thus, it was possible to simulate a radioactive medium that appeared on Earth due to the large number of minerals on the surface.

Periodically, scientists allowed the water from the mixture to evaporate. So it was possible to simulate the disappearance of small reservoirs. As a result of the experiments, a large number of compounds appeared, including amino acids, which subsequently led to the appearance of RNA – ribonucleic acid. It is an integral part of the molecule.
