In 1938, the discovery of a large, unusual fish turned the scientific community on end. Dubbed a "living fossil," the discovery of a coelacanth in South Africa shocked scientists around the world who thought this type of fish had died out millions of years prior during the process of evolution. Today, living fossils are organisms preserved in the fossil record that still exist in similar form today. Their existence challenges the core concepts of evolution and creates a fascinating debate among scholars. Do they indicate a younger earth than some have thought, placing the millions-of-years evolutionary timeline into question? Or do living fossils represent a deep mystery?
