Scientists: All life on Earth consists of 20 amino acids
Scientists have discovered that there were about 500 types of amino acids on Earth, but life was born only thanks to 20 of them.
In the course of several decades, researchers tried to find out how the first amino acids interacted with each other in order to form protein molecules.
Scientists conducted an experiment to find out. Arginine, lysine and histidine are placed together with non-biological elements that competed with each other.
These acids were subjected to conditions that previously existed on our planet.
As a result, the amino acids randomly formed small segments that were linked. According to the study, only 20 amino acids from all participated in the creation of life.
