Dentition of a modern baboon (IMAGE) Max Planck Institute for Chemistry Caption Dentition of a modern baboon (Papio ursinus). These savanna dwelling omnivores provide a prime analogous model for early hominin evolution. They evolved and radiated in parallel with hominins within a similar landscape and time frame. Tina Lüdecke and her colleagues use tooth enamel from dentitions like this to develop the new method. Credit Tina Lüdecke Usage Restrictions Credit must be given to the creator.
