The birth of life

The theories which explain the birth of life include spontaneous generation, biogenesis, universal influx theory and such various theories but most commonly accepted theory in the academic world is the chemically evolution theory. In 1936 Russian biochemist A. I. Oparin wrote his “The Origin of Life” and presented a hypothesis relating to the start of life.
The methane (CH4), ammonia (NH3), water vapor (H2O) and carbon dioxide (CO2) which reached the original air had a chemical reaction which resulted in a production of simple organic compounds. It is said that as these collected and formed the birth of complex life. In 1953 America’s S. L. Miller succeeded in taking methane, ammonia, water, hydrogen and kept these in a sealed container for a week, adding electrical shocks and produced amino acid. This is to say the fact that organic substances form from inorganic substances was demonstrated by experiment. Afterwards this experiment was complemented by a lot of scholars. Finally Oparin’s thinking and Miller’s experiment resulted in a common structure of concept.

It was deduced that through the evolution of chemistry the earliest life was already made and while eating organic substances in order to gain energy and was thought to be the heterotroph. Rather than making energy directly by its self it was way more beneficial to use energy which was already produced. However with the decrease of the organic substances which existed in the ocean came the appearance of the autotroph which was able to make its own nutrients.

If that were the case then where was life produced? At the time the Earth would have been an extremely barren environment to live in. Then, there was no air like the air which exists now and strong ultraviolet rays would have been in contact with the life on Earth. This kind of exposure to ultraviolet rays is means death for life. As a result it is speculated that the earliest life was produced in the deep sea, where sun rays could not reach.

The sun is death as well as the root for life. This is to say sunlight provides energy which enables life to live. If so, it leaves a question of how the life could have survived in the deep sea where the sunlight could not reach. This doubt was solved by the discovery of deep sea hydrothermal vent. The black smoke emitted from the deep sea hydrothermal vent included hydrogen sulfide which could be used as energy for various forms of life and. The present deep sea hydrothermal vent is being researched in an important position in relation to the origins of life.
