Restos fósiles

The video explores the history of life on Earth through fossils, which are remains or impressions of ancient organisms. Fossils form when organic matter is preserved by sediment or ice, and minerals replace the organic material. They can be bones, shells, or even whole organisms. The age of fossils is determined by their depth in the strata, with deeper fossils being older. Fossils reveal how species have evolved over millions of years. A paleontologist analyzes a dinosaur fossil, noting differences between northern and southern hemisphere species, illustrating evolutionary changes due to habitat separation. Fossils provide insights into the evolution of both extinct and extant species.
