GEOLOGY

Detailed explanation-1: -Fossils also show how animals changed over time and how they are related to one another. Fossils can’t tell us everything. While fossils reveal what ancient living things looked like, they keep us guessing about their color, sounds, and most of their behavior.

Detailed explanation-2: -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: -Explanation: Archaeopteryx is not a living fossil in fact it is a connecting link between the birds and the reptiles while King crab, Sphenodon, and Peripatus are the living fossils.

Detailed explanation-4: -Fossils are the remains or traces of plants and animals that live a long time ago. Fossils help scientists understand what life was like millions of years ago. Some fossils provide evidence of living things that have gone extinct, which means they no longer found alive anywhere on earth today.
