Fossil Ape Teeth May Lead to New Insight On Early Human Evolution

New research by Tanya Smith, Professor in the Australian Research Centre for Human Evolution & Griffith Centre for Social and Cultural Research, Griffith University, and Daniel Green, Postdoctoral Research Scientist, Columbia University, has brought a new academic approach that leverages tooth chemistry and growth to extract information about seasonal rainfall patterns from the jaws of living and fossil primates.

The pair found several aspects in their work that proved helpful for understanding the link between environmental patterns and primate evolution. "This novel research approach, coupled with our fossil ape findings and modern primate data, will be crucial for future studies of hominin evolution - especially in Kenya's famous Turkana Basin," Smith and Green wrote for The Conversation.
