Scientists: the cradle of mankind is a volcanic lake
Experts believe that the hot and fresh water could contribute to the development of life on Earth.
The first primitive living cells could appear in the waters of fresh lakes, which is heated and saturated with minerals prehistoric geothermal sources. Most geologists and evolutionary biologists believe that life on Earth in its modern form originated in the waters of the primary ocean that covered almost the entire surface of the planet.
It is believed that this ocean was a thick broth of amino acids and other “building blocks of life,” from which came the first living cells.
A group of geologists and evolutionary biologists under the guidance of a native of Russia, Evgeny Kunin from the National institutes of health in Bethesda (USA) has offered a new argument in favor of the alternative theory of the origin of life in freshwater lakes, in which water enters the steam and hot water from geothermal sources.
In recent years there have been a lot of evidence that the activity of volcanoes and other geothermal processes played an important role in the origin of life, reports ” RIA-news “.
So, in February 2010, British and German geologists have proposed a new theory of the origin of life, according to which the first cells emerged at the vents of underwater volcanoes and then colonized the entire World ocean.
In their study, the authors suggested that the primary cells had to evolve in that country, which was distinguished from them by chemical composition.
From this point of view, seawater is not an ideal environment for the development of life – the concentration of sodium, potassium, manganese, zinc ions and other essential bio-elements it is significantly different from cell.
It turned out that the crater lake were most favorable “cradle” for the emergence of life. As noted by Kunin and his colleagues, only in their waters has a sufficiently favourable conditions for the formation of the basic structures of proteins and other essential molecules that make up the base of the cell.
