Living Fossils Are Dead! Long Live Living Fossils

The video explores the concept of living fossils, initially coined by Darwin, and how it has evolved over time. While some species appear unchanged, genetic studies reveal significant evolutionary changes. The term 'living fossil' is contentious, but efforts are underway to standardize its use, focusing on organisms with ancient lineages. Researchers propose criteria like the Evolutionary Performance Index (EPI) and the concept of Endangered Living Fossils (ELFs) to identify and protect these species. The video highlights the importance of genetic diversity and conservation in understanding evolutionary and geologic history.
