In mid-October of this year found a place where many billions of years ago, there were signs of life on Earth. Scientists believe that the mud volcanoes. Isua. the south-west Greenland became the cradle of the earliest simple life forms. About 4 billion years ago, these volcanoes have created a comfortable environment in which the first biomolecules could be formed by the chemical composition of the medium.
For the first time scientists have stumbled on a completely suitable for. the origin of life. environment in volcanic rocks, numbering 3.8 billion years. This discovery was made by geologists from the University of Lyon, whose study is published in a scientific journal. Proceedings of the National Academy of Science.
The mineral serpentine, which is composed of these volcanoes are often used in the manufacture of jewelry. It is also called the coil, it has a distinctive dark green color. This rock appears in subduction zones where oceanic plates collide and one goes to another.
Mud volcanoes, which are investigated by French scientists, have come out in this area, they have risen to the surface of the planet almost immediately after the formation of the Earth's core.
It is believed that life could arise near the hydrothermal vents located on the ocean floor. They are called ' black smokers ', because they are surrounded by thick clouds of dark smoke emission due to the large ore components. Environment in areas with underwater geysers rich in hydrogen, methane and ammonia. These chemicals may have contributed to the birth of early life forms. However, scientists are always alarmed the high acidity of the medium, because in such conditions, free amino compounds could not be stable, that is, could not form the organic molecules - the most simple forms of life.
A research team led by Francis Albareda came to the conclusion that it is Isua volcanic rocks, which are the oldest on the planet could create conditions in which the simple amino acids connected to a complex formation. Not a very high temperature and alkaline qualitatively distinguish them from ' black smokers '.
Interestingly, the zinc content of Isua Wednesday reminiscent of that which now exists in the vicinity of the Mariana volcanic chain in the Pacific Ocean, where there is a cluster of submarine volcanoes. This is the modern area of the collision of continental plates.
