Life on the planet emerged simultaneously with the formation of an independent ability to develop, and the ability to fix carbon, which is very difficult. The fact that carbon dioxide, which is in its structure in the world, is a very stable compound, therefore, to use the carbon system must pass through the stage of unstable states. The cells are taken through carbon chemicals from the environment, building of them then the products that support livelihoods. The scientists presented their hypothesis in the publication of Physical Biology, said that the relationship between the geochemistry of the Earth and the biochemistry of life passes through unstable connections.
"Think of life as a growing bulb, in which each layer is responsible for assuming the role of a feedback mechanism that stabilizes and improves the ability to fix carbon" — suggests the researchers, led by Professor Eric Smith.
Having mastered the process of carbon fixation, a chemical system can be expanded in uncountable variations and combinations. The authors believe that life can be like that and some of the other planets, which is a liquid, there is volcanic and tectonic activity, and throwing in hydrothermal vents chemicals creates potential conditions for life. In other words, heat, liquid and chemical diversity — is required for the existence of extraterrestrials.
