Contrary to the belief that paleomagnetic reversals are not biologically significant, we find good reason to think otherwise. Attention is drawn to polarity transitions, time intervals a few thousand years long that follow the collapse of the existing geomagnetic dipole moment and precede the establishment of the new, oppositely directed moment. The geomagnetic field during transitions is reduced to a maximal mean intensity about 10% of the stable field and can exhibit low-frequency perturbations comparable to numerous laboratory-based extremely low frequency (ELF) studies reporting biological interactions, making it very likely that similar interactions must occur over the course of a polarity transition. This conclusion is strengthened by reports of medical problems that significantly correlate with intense solar winds, events that also generate ELF perturbations similar to those that can occur during polarity transitions.
与古地磁反转没有生物学意义的观点相反，我们有充分的理由认为并非如此。人们的注意力被吸引到极性转变上，这是一个长达几千年的时间间隔，它发生在现有地磁偶极矩崩溃之后，新的、方向相反的偶极矩建立之前。在转变过程中，地磁场强度降至稳定场最大平均强度的约10%，并且可能会出现与众多基于实验室的极低频（ELF）研究中所报告的生物相互作用相当的低频扰动，这使得极性转变过程中很可能会发生类似的相互作用。与强烈太阳风显著相关的医学问题报告进一步强化了这一结论，太阳风事件也会产生与极性转变期间可能出现的类似的极低频扰动。
