Variations in spectral characteristics of the Kp-index of geomagnetic activity during the solar activity cycle were studied in order to assess the role of its rhythms in the formation of temporal structure of biological objects. It is shown that most spectral components of the Kp-index are modulated by the 10.5-year periodic rhythms in solar activity variations, while its circasemiseptan component (3.5 days) exhibits an 11-year rhythm. Since it is a circasemiseptan rhythm that is characteristics of biological objects (e.g., unicellular algae), it can be assumed that geophysical rhythms played a substantial role in the formation of biological rhythms during evolution.
为了评估地磁活动Kp指数的节律在生物对象时间结构形成中的作用，研究了太阳活动周期内地磁活动Kp指数光谱特征的变化。结果表明，Kp指数的大多数光谱成分受太阳活动变化中10.5年周期节律的调制，而其近七日节律成分（3.5天）呈现11年节律。由于近七日节律是生物对象（如单细胞藻类）的特征，因此可以假设地球物理节律在进化过程中生物节律的形成中发挥了重要作用。
