Which animal can detect the Earth's magnetic field using cryptochrome proteins in its eyes, effectively 'seeing' magnetic field lines as a visual overlay — a sense scientists call magnetoreception?

Accepted Answer

European robins. European robins are among the best-studied animals with quantum-assisted magnetoreception. Cryptochrome proteins in their eyes are thought to create quantum entangled electron pairs that are sensitive to Earth's magnetic field, helping them navigate during migration.

Question 4

Which famous American novelist wrote all his manuscripts standing up at a custom-built chest-high desk, claiming that sitting down made him feel too comfortable to write honestly?
