EVERYDAY SCIENCE

Detailed explanation-1: -Fossils are key evidence that helps study evolution and the adaptation of different organisms to the environment. It provides the record of how organisms evolved and is represented as the tree of life.

Detailed explanation-2: -Why do we study fossils? Fossils give us a useful insight into the history of life on Earth. They can teach us where life and humans came from, show us how the Earth and our environment have changed through geological time, and how continents, now widely separated, were once connected.

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: -They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited. Finally, and if the fossil record is complete enough, their study can help us better understand the evolution (or progression) of life through geologic time.

Detailed explanation-5: -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.
