Only the third statement is true.
- Dark matter has been proposed to explain observed gravitational effects (galaxy rotation curves, gravitational lensing, cosmic microwave background patterns).
- It has not been identified as a cause of biological mutation.
- It has not been directly observed or measured; its presence is inferred from its gravitational effects and is the subject of ongoing searches.
