Life was Born on Land, not from the Mother Sea

It was "Mother Spa" not "Mother Nature"

Although Charles Darwin proposed in 1871 that life originated from a " small warm water puddle ", the mainstream theory so far was " Life was born from the ocean ". However, that common opinion may be overturned. Because fossils were discovered indicating that there were microorganisms on land before 3.5 billion years ago .

According to the New Scientist, the team that is founded by Tara Djokic of New South Wales University in Australia, found a fossil of 3.5 billion years ago. In the hot and dry remote province of Western Australia, in the Pilbara area, we discovered rocks of 3.5 billion years ago, where traces of microorganisms inhabited on land from the former volcanic site of the dresser bed were found.

This fossil, of the rock with the structure of the microorganisms made layered stromatolites bubbles of marks that appear to be trapped by mucus and microorganisms.

The reason why the theory that "life is born from the sea" is the reason why it is preferred that the traces of microorganisms living in ancient times are lacking on land. Until recently the oldest evidence of life on land was the fossil of 2.8 billion years ago, whereas the oldest evidence in the ocean was 3.7 billion years ago.

By this discovery, it was confirmed that microorganisms existed in both land and ocean at almost the same time, so the question of which was the first to emerge.

According to Djokic, who thinks that life was born from onshore hot springs like Darwin, a small amount of water such as a hot spring is more likely to be evaporated and the constituent elements of life can be agglutinated, so the conductivity to form life It seems there may have been. In addition, "In hot springs, different minerals come up by circulating warm liquid between the rocks underneath, so there are mixtures with high nutritional value of ingredients".

But it seems premature to exclude the theory that uses the sea as the origin of life, and Gregory Webb at the University of Queens said that this discovery is wonderful while stating that it is difficult to declare early Earth life It was.

This is a video released by New Scientist .

Further investigation is needed about 'the birth of life', but this discovery may give a new perspective to life search on Mars .

Both the Earth and Mars were formed about 4.5 billion years ago, both of which had volcanoes and hot springs, so Djokic says, "If life dates back to the hot springs if it dates back from the history of the Earth, The possibility that it existed also in hot springs is high ".

NASA's "Mars 2020" space vehicle mission landing site is likely to be, Columbia Hills, which was once said to have a hot spring.

Discovery on the Earth may contribute to the discovery of life on Mars.
