Fossilized bones are revealing secrets from a lost world

The discovery of preserved metabolic molecules in fossilized bones marks a significant advancement in paleobiology, allowing for a more nuanced understanding of ancient life. By analyzing these molecules, researchers can gain insights into the ecological dynamics of prehistoric environments, which may challenge or refine existing theories about evolution and adaptation. The implications of identifying ancient parasites also open new avenues for understanding the co-evolution of species and their pathogens over millions of years.
