Detailed explanation-1: -Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record.
Detailed explanation-2: -Scientists use fossils to learn about how environments and ecosystems have changed over long periods of Earth’s history. By comparing fossil species to modern species, scientists can learn about populations, ecosystems, climate, and the type of biome in the area at a certain time in Earth’s history.
Detailed explanation-3: -Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history. They can also help scientists reconstruct the evolutionary histories of present-day species.
Detailed explanation-4: -Fossils are essential evidence for evolution because they show that life on Earth was different in the past than it is now. They can use techniques like radiometric dating to determine the age of fossils and so classify them to determine evolutionary links between things.
