The article Did the Earth’s magnetic field affect our evolution? on Pledge Times cite this Science paper to assert:

These authors speculate that, in the Pleistocene, large mammals could have reached a natural limit of body size until the arrival of Laschamps, when the probability of cell mutation would increase at times of high ultraviolet ray flux. It would not be a catastrophic, instantaneous extinction, but rather an accumulation of mutations produced by radiation over multiple generations, over several thousand years, which is the duration of the minimum intensity of the geomagnetic field during geomagnetic inversions.

My question is: Is there any study correlating other geomagnetic inversions with extinctions in fauna?

  • $\begingroup$ The paper goes a long way speculating. No direct evidence on the northern hemisphere connects Laschamps excursion (or any precursory phase, or any geomagnetic excursion in earth's history at all) to an extinction, and the climate record is actually quite good. $\endgroup$ – user22279 Apr 25 at 16:28
