The linkage between astronomical cycles and the periodicity of mass extinctions is reviewed and discussed. In particular, the apparent 26 million year cycle of global extinctions may be related to the motion of the solar system around the galaxy, especially perpendicular to the galactic plane. The potential relevance of Milankovitch cycles is also explored in the light of current evidence for the possible causes of extinction events over a geological timescale.
本文回顾并讨论了天文周期与大规模灭绝事件周期性之间的联系。特别是，全球灭绝事件明显的2600万年周期可能与太阳系围绕银河系的运动有关，尤其是垂直于银盘的运动。根据当前关于地质时间尺度上灭绝事件可能原因的证据，还探讨了米兰科维奇周期的潜在相关性。
