Paleontology is the scientific study of the history of life on Earth through the examination of plant and animal fossils. This field combines aspects of geology and biology to understand how organisms evolved over millions of years. Fossils, which are the preserved remains or traces of ancient life, provide crucial insights into the past environments and ecosystems. Paleontologists, the scientists who specialize in this field, analyze fossils to reconstruct the appearance, behavior, and habitats of extinct species. Their work helps us understand the processes of evolution and extinction, shedding light on how life has changed over time and how it may continue to do so in the future.
