How life emerged on Earth? The old theory is removed

The argument is the fact that, until now, knew too little information on how life on Earth is driven.

For several decades, the main hypothesis on the origins of life was linked to the formation ,, primordial soup ", an event which would have occurred during the first bodies as a result of a chemical reaction triggered within an area with warm water. Recent research however, indicate that life on Earth would have appeared in the depths of the oceans, in the so-called hydrothermal vents ,, ".

A study published in the journal Nature Microbiology suggests that the oldest common ancestor of all living beings is fed with hydrogen as a gas in a high temperature environment, such as hydrothermal vents. On the other hand, the primordial soup hypothesis ,, "says that life would appear when an energy source came into contact with water from the Earth's surface, creating simple molecules first. They were subsequently grouped into structures DNA, which in time led to the formation of the first living organisms.

Recent studies made on genes that most likely were present and there were first living cells on Earth have shown that organisms first appeared on our planet in the deep-sea hydrothermal vents. From within these structures, the alkaline fluids penetrate into the ocean water, producing the natural gaps proton concentrations in a manner similar to the activating all living cells.

The research conducted recently suggests that in the early stages of development of living organisms, chemical reactions in the cells of these variations were driven proton. Then, the cells were able to reproduce these individual differences out of the area of ​​activity of hydrothermal vents, colonizing the oceans and, eventually, the entire planet.

Hydrothermal vents are the only known natural structures that could constitute places of occurrence of the first organic molecules. Aeastă hypothesis was accepted on ,, detriment of primordial soup "because until now knew very little about the principles that govern how life is driven.
