Final answer:
Fossils are preserved remains of organisms from the past, providing evidence for evolution. Paleontologists study fossils to understand how species have changed over time.
Step-by-step explanation:
Fossils and Paleontology
Fossils are the preserved remains of animals, plants, and other organisms from the distant past. They provide clear evidence for evolution. Paleontologists are scientists who study fossils to learn about life in the past. When scientists first found dinosaur fossils, they had no way of providing what it was at the time. Instead, they made an educated guess called Reconstruction. Paleontologists compare the features of species from different periods in history to understand how species have evolved over millions of years.
