The first living things on Earth were microscopic organisms microbes These prokaryotic organisms were unicellular and lacked a defined nucleus or other membrane The microorganisms that live near such plumes have led some scientists to suggest them as the birthplaces of Earth s first life forms Organic molecules may also have formed in certain types of clay minerals that could have offered
Ancient fossilized microbial mats of cyanobacteria called stromatolites date back to 3 7 billion years Ancient Australian rocks have isotope signatures suggestive of life that date The origin of life deals with how the first living organisms formed from non living matter Researchers have proposed different scenarios based on evidence from Earth s
