According to a new study, tiny ripples of sediment on ancient seafloor, captured inside a 3.7-billion-year-old rock in Greenland, may be the oldest fossils of living organisms ever found on Earth.In the Isua Greenstone Belt in southwestern Greenland, there was a discovery of the oldest rocks on the Earth's surface. Layered mounds of sediment and carbonates that build up around colonies of microbes that grow on the floor of shallow seas or lakes. More than 4 billion years ago, a period of intense volcanic activity when large meteorites and icy comets frequently bombarded Earth. That was once subject to intense underground heating and pressure, which distorted their original shapes and changed their chemical composition of the rock. This discovery is a huge new study that is found to be very interesting in the science communitty. Those 3.5-billion-year-old stromatolites, found in sedimentary rocks are found to be similar to the environment in Mars today, and , may hold many answers to how life started. It is a very valuable piece in the science community, and further studies are yet to be held for this new discovery.
