PALAEOMAGNETIC samples show a number of polarity transitions in the Earth's dipole field, and there seem to have been marked evolutionary changes in flora and fauna near the time of several of the reversals1. Suggestions that when the magnetic dipole moment decayed during a reversal, there would be an increase in radiation producing a sudden increase in the rate of evolution2 seem to have been discarded without considering whether the atmospheric mass would be reduced1,3. Mariner V observations… Expand
