The Fossil Record

The fossil record is a collection of preserved remains and impressions of ancient organisms found in sedimentary rocks. It provides evidence of the history of life on Earth, showing how species have evolved and changed over millions of years. Fossils help scientists understand past ecosystems, climates, and the process of evolution. By studying the layers of rock where fossils are found, researchers can also determine the relative age of different species. This record is crucial for understanding biodiversity, extinction events, and the relationships between different life forms throughout Earth’s history.
