Cosmic ray intensity at Earth's surface would be greater when Earth's magnetic field passed through a zero phase because magnetic shifting is minimal. Fossil evidence suggests that the periods of no protective magnetic field may have been as important in changing life forms as x-rays have been in the famous heredity studies of fruit flies.

Cosmic radiation would increase substantially, probably wiping out many life forms.
