400,000-Year-Old Teeth in China Reveal the First Molecular Evidence from Homo erectus
Chinese scientists have recovered the first molecular data from Homo erectus, using proteins preserved inside 400,000-year-old teeth from China. The discovery, published in Nature, does not involve ancient DNA. Instead, it opens a rarer and more durable archive: tooth enamel, where biochemical traces can survive long after genetic material has disappeared. For a species long…
