Reversal of magnetic poles upon migration

  1. Jan 11, 2007 #1
    Will a sudden change in the orientation of earth's magnetic poles have catastrophic consequences for migrating species?

    1] They don't tend to be sudden.

    2] Migrating species seem to have survived the reversals that have been happening every eon since the dawn of time.

    You make two good points, but I do not understand the link you provided.

    Animals in general have survived, but do migrating species particularly suffer? Are times required for species adaptation to magnetic pole reversals comparable (<,=,>) to the reversals themselves?

    Interesting arguments toward the end of the article. For now, I'm sold. Here is the pertinent exerpt from the article Evo provided:
    Let's hope.
