It remains one of the most accepted and controversial theories in the scientific world that living things have evolved throughout history and continue to evolve through natural selection. Agree, foundations of evolution where does it start?

While most people think of cell-sized creatures, this is not the case. A new study has even provided important clues about the common ancestor of all living things on Earth. Evolution, It continued even when there was no living thing on earth.

Let’s explain it slowly: the living world owes its existence to 20 amino acids:

Proteins that play a crucial role in the functioning of our cells, only 20 amino acids occurs in different orders. But in nature and in the universe, there are actually not so few amino acids. For example, in a meteorite that fell just above Australia in 1969 85 different amino acids was found.

So why did nature choose only the 20 amino acids that make up life as we know it today? The scientific world assumes that 10 of these 20 amino acids came from the atmosphere and meteorites during the formation of the Earth. But other There was no information on the selection of 10 amino acids.

New research sheds light on how that choice came about:

In a new study published by the American Chemical Society, scientists Earth 4.6 billion years ago simulated. Simulation on Earth primitive protein synthesis rebuilt.

20 amino acids present in all living things, from bacteria to humans, according to simulation. by natural selection chosen. He was seen to choose organic compounds, amino acids that will form proteins, considering the benefit the protein would provide according to its function.

In other words, it is not the most abundant amino acid in nature. amino acids that will contribute most to the protein’s job had been chosen.

This proved that even in chemical molecules there was natural selection before there was life on our planet. In this way, the source of 10 amino acids, the choice of which is mysterious, has a new theory.
