According to fossil records, life first appeared on the earth about 3.5 billion years ago, but how life appeared on the earth is still one of the unsolved mysteries in the scientific community.
According to foreign media reports, after billions of years of development, there are different kinds of life on the earth, and it is also the only planet with life that we know at present. For the formation of early life, scientists have made new discoveries.
For the formation of the universe, many scientists believe that it was formed by the expansion of a dense and hot singularity after a big explosion 13.7 billion years ago, which laid the material foundation for the earth. As a planet, the earth originated from the primitive solar nebula 4.6 billion years ago.
Previous studies have shown that,Stromatolite is considered to be the origin of organisms, but this theory has not been confirmed.A recent study published in nature communications provides clues to the formation of early life on earth.
By analyzing and studying the stromatolites in this area,
In general, it is difficult to leave fossils after the death of microorganisms in the early stage of the earth,Scientists have to look for other indirect evidence to prove their existence, and organic compounds in their food or decomposition products are one of the best evidence.
