What Are Living Fossils? Meaning, Examples, and Why They Still Exist Today - Sassy Feeds

Living fossils are species that have remained almost unchanged for millions of years and still exist today, offering insights into Earth's evolutionary history. Examples include the coelacanth, horseshoe crab, ginkgo tree, tuatara, and nautilus. They survive due to stable environments, low competition, successful body designs, and slow evolution. Although they appear unchanged, their DNA and internal biology have evolved. Living fossils help scientists understand evolutionary history, ancient ecosystems, and survival strategies.
