There hasn't been a great deal published on that particular aspect of the 
varying magnetic field, but I suspect that there is not a great effect on 
most life -- the Earth's magnetic field changes orientation regularly, and 
the complete polarity reversal doesn't seem to coincide with any particular  
increase in extinction or species emergence. Some migratory species may 
be affected: some use the Earth's magnetic field as a navigation aid.
