Stromatolites—layered rock structures built by ancient microbes—are revealing how early life thrived in extreme environments like post-impact crater lakes and even on land. New research uses AI and geological analysis to decode these microbial fossils as windows into Earth's earliest oxygen-producing life and the origins of complexity.
·Crater lakes formed after asteroid impacts provided ideal conditions for early oxygen-breathing organisms
·AI technology is detecting previously invisible signatures of ancient microbial life in stromatolite formations
·Some stromatolites defied expectations by forming in terrestrial rather than purely aquatic environments
·Modern stromatolites in Australia preserve records stretching back billions of years to Earth's oldest life
·Microbially induced structures are being studied as keys to understanding how simple life became complex
