The fossil record provides evidence for the idea of natural selection by showing how species have changed over time. Fossils of organisms that lived in the past show how they were adapted to their environment, and how they changed over time to become better adapted. For example, fossils of early horses show that they had four toes, while modern horses have only one toe. This suggests that horses evolved over time to become better adapted to their environment. Additionally, the fossil record shows that some species have gone extinct, which suggests that they were not able to adapt to changing environmental conditions. This provides further evidence for the idea of natural selection.
