Researchers have found the oldest known microorganisms in 3.5 billion-year-old rocks from Australia's Pilbara region, which could end a long-standing debate about early life forms. These ancient rocks, specifically from the Dresser Formation, contain layered structures called stromatolites, and recent studies have revealed exceptionally well-preserved organic matter, including biofilm-like strands. This evidence suggests these structures were created by living microbes, possibly using sulfur as an energy source, which aligns with theories about the origins of life. While some researchers remain cautious, the use of multiple analytical methods to support these findings adds to their credibility.
