Answer:
Microbial mats.
Explanation:
Microbes formed sheets that were able to capture layers of sediment is called microbial mats. These mats of microbes provide good fossil evidence to the researchers. These microbial mats consist of bacteria and archaea which is considered the earliest form of life on earth. These microbial mats grow on moist places as compared to dry environment. About 3,500 million years ago, these microbes are the most important members of earth and maintainers of the ecosystems.
we have been evolved through same root, during the process we get separated and develop new features to adjust in the surrounding atmosphere, that's why our genes are matching with fruit flies and others.
Species 3&5 because they have the lowest number
I think c is the answer but I’m not sure
The answer is; prokaryotes are the earliest life forms
Glycolysis was the earliest energy harvesting pathway in early living organisms. Glycolysis does not require oxygen attribute to the early condition of the earth where its atmosphere was majorly comprised of carbon dioxide. It is only after the great oxygenation event that life evolved the oxidative phosphorylation process.
