Quantum Microscopy Uncovers Neanderthal Fire Evidence in Ancient Sites

Researchers employed quantum diamond microscopy to analyze ancient hearth deposits in El Salt, Spain, revealing previously undetectable magnetic traces. This advanced physics method provided new insights into Neanderthal fire-making practices, indicating the use of fibrous plant materials as fuel and high-temperature burning. The findings offer a deeper understanding of daily life for Neanderthals tens of thousands of years ago.
