### Explanation of how the fossil record provides evidence for the idea of natural selection:
The fossil record provides evidence for natural selection by showing how species have changed over time in response to environmental pressures. Fossils reveal transitional forms, indicating how species adapted their structures for survival, such as changes in limb shape for movement or skull size for brain capacity. Additionally, when fossils show a gradual change in traits, it supports the idea that those traits were selected for over generations, leading to the evolution of new species. This pattern of change aligns closely with the principles of natural selection proposed by Charles Darwin.
