Quick Summary

A "living fossil" is an organism that has remained largely unchanged from its ancient ancestors, with few or no close relatives still alive today. These organisms provide a unique glimpse into past life forms because their basic structure has persisted over vast geological timescales.12

Examples of living fossils include horseshoe crabs and ginkgo trees. Pelican spiders are also considered living fossils due to their ancient fossil record and minimal changes over time. While most organisms evolve and change significantly, some, like the brachiopod Lingula, have shown little morphological evolution for hundreds of millions of years. The study of fossils is crucial in paleontology and stratigraphy, helping scientists understand Earth's history and the evolution of life.1324
