Tooth Enamel Unlocks Genetic Secrets of Ancient Human Relatives
A new study of two-million-year-old tooth enamel has revealed surprising genetic diversity in Paranthropus robustus, a distant upright-walking relative of early humans. Using paleoproteomics—the analysis of ancient proteins—researchers extracted molecular data from fossil teeth found in South Africa’s Swartkrans Cave, offering one of the oldest glimpses into human ancestry ever recovered from the continent. Proteins ...
