How would an intelligent species evolve if its members could see magnetic fields ?
For example, if they could visualize magnetic fields in the atmosphere like birds, as you read about in this paper, about how migrating birds use quantum effects to navigate, quoting :
" But unlike humans, birds also detect the magnetic field generated by Earth’s molten core and use it to determine their position and direction. [...] Our experimental evidence suggests something extraordinary: a bird’s compass relies on subtle, fundamentally quantum effects in short-lived molecular fragments, known as radical pairs, formed photochemically in its eyes. That is, the creatures appear to be able to “see” Earth’s magnetic field lines and use that information to chart a course between their breeding and wintering grounds.
