The evidence from the fossil record that supports the observation that life changes over time includes:
- **increased numbers of fossils of different species found in younger rock layers**: This indicates that biodiversity has increased over time and that new species have emerged.
- **fossils of distant relatives of a modern species found in ancient rock layers**: This provides evidence of evolutionary change, showing how current species are related to past forms.
The other options do not directly support the observation of change over time:
- **several rock layers that do not contain fossils**: This does not provide evidence of life changing; it simply indicates periods where fossilization did not occur.
- **more fossils of the same species found in several rock layers**: This suggests the persistence of certain species but does not indicate change over time.
Therefore, the correct choices are the first and fourth options.
