Scientists have discovered the oldest microflora fossil so far, with a history of about 3.77 billion years

Tencent science news according to foreign “Digital Journal” website reported that scientists from University College London have found the oldest microbial fossils in Canada.

researchers found fossils in the quartz layer of Nuvvuagittuq crustal zone The Nuvvuagittuq crustal zone is rich in fossil resources and contains the oldest known sedimentary rocks on the earth

These rocks were formed in a deep-sea hot spring rich in iron.

deep-sea hot springs provided habitat for the first life forms on earth, dating back to about 3.77-4.3 billion years ago. The discovery of

is not only very important in fossil dating, but also provides evidence for the theory that life on earth originated from submarine hot springs
the earliest form of life on earth mdash; mdash; bacteria appeared shortly after the formation of the earth

The newly discovered fossils are older than the oldest microfossils ever discovered before. The oldest microfossils,

, were found in Western Australia, with a history of about 3.46 billion years. The discovery of these microfossils has also sparked controversy. Some scientists believe that they are prehistoric rocks of abiotic origin This scientific field belongs to microfossils, and microfossils are common features of geological logging

The scientists carefully examined the newly discovered fossils to determine whether they came from biological or non biological origins.

in order to evaluate, the scientists used various methods to study, taking into account the effects of temperature and pressure.

these analysis results indicate the biological origin of the fossil In particular, the structure of hematite in fossils is similar to that of iron oxidizing bacteria found near hydrothermal vents today.

hot night fountains usually exist in areas of volcanic activity, plate tectonics and ocean basins

Dr Dominic Papineau, who led the study, explained: “we have found evidence of one of the oldest forms of life on earth.

this discovery helps us to link the history of earth with life on earth, and will help us identify traces of life in the universe; The discovery suggests that both Mars and earth had liquid water on the surface when life on earth was formed.

suggests that there may have been extraterrestrial life on Mars, or at least life forms existed at some time
