fossil records

DNA evidence

case studies

Answer 1

Check all three.

- DNA evidence — reveals genetic relationships, common ancestry, and molecular changes.
- Case studies — observational and experimental studies (like Darwin’s finches) document natural selection and evolutionary change in real populations.
