Scientist A: Bees use the Earth’s magnetic field to navigate back to their hive. Scientist B: Bees use visual landmarks like trees and hills. An experiment is conducted on a perfectly flat, featureless salt plain with no landmarks. A group of bees is released with a small magnet attached to their heads that disrupts magnetic sensing. A second group has a non-magnetic weight.
If both groups fail to find the hive, what is the best interpretation?
- The result proves Scientist A is correct because the magnetic disruption caused the first group to lose their sense of direction entirely.
- The experiment is flawed because bees never fly over salt plains where there are no flowers to provide a reason for navigation.
- The failure of both groups suggests that visual landmarks are necessary for navigation, supporting Scientist B.
- Both scientists are supported because bees always require a combination of magnetism and landmarks to find their way home.
