Answer:
I don't exactly know too much about fossils and current animals, so I'll try my best.
Explanation:
Fossils provide evidence about life on Earth that currently extinct. Through fossils, we've discovered several species of animals and plants that previously existed. We also learn how life on Earth changed throughout the years. Fossils found in younger rocks look like animals and plants that are living today. Fossils in older rocks look less like the current living animals and plants. Some fossils found look either more or less like current species we know today.
