Researchers have discovered chemical traces of life in rocks older than 3.3 billion years, offering a rare look at Earth’s earliest biology. By combining advanced chemical methods with artificial intelligence, scientists were able to detect faint molecular patterns left behind long after the original biomolecules disappeared. Newly analyzed fossils, including ancient seaweed from Canada’s Yukon Territory, helped validate the method and deepen understanding of early ecosystems.
