Arrange the sentences into the correct order.
Put the sentences in the correct order:
- This experiment provided strong evidence that magnetic sensing, not merely visual landmarks or the sun, is central to how migratory birds chart their course.
- To test this, scientists placed robins in controlled chambers where the magnetic field could be artificially rotated, and the birds consistently reoriented their attempted flight direction to match.
- Research eventually revealed that these birds possess a light-sensitive protein in their eyes that allows them to perceive the Earth's magnetic field as a visual pattern.
- The central question was how a bird with a brain the size of a pea could reliably find its way across such vast, featureless distances.
- Each autumn, the European robin travels thousands of kilometres from its breeding grounds to wintering sites, navigating with an accuracy that puzzled scientists for decades.
