what type of fossil evidence support the origin of life. one paragraph only

1 answer

Fossil evidence that supports the origin of life primarily includes stromatolites, which are layered structures produced by the activity of microbial mats, predominantly formed by cyanobacteria. These ancient fossils date back over 3.5 billion years and provide insight into early microbial life and its role in shaping the Earth's environment. Additionally, carbonaceous microfossils and isotopic signatures, such as the presence of carbon isotopes (^12C and ^13C) suggesting biological activity, further indicate that life existed in Earth's primordial conditions. Such fossils illustrate not only the existence of early life forms but also their capacity to influence atmospheric and geological processes, paving the way for the evolution of more complex organisms.
