研究人员强调了在过去250 Myr(百万年)的地球历史中，海洋属的多样性以及构造、海平面和宏观地层数据的一个共同的、相关的 36±1 Myr旋回。36±1 Myr旋回在构造数据中的突出地位有利于一种共因机制，其中地质作用力机制驱动生物多样性和保存的岩石记录中的模式。
特别的是，研究结果表明，一个36±1 Myr的构造-海平面旋回可能源于对流地幔的俯冲板块之间的相互作用，从而调节地幔-岩石圈深水循环。生物多样性的36±1 Myr构造-海平面上升驱动力可能与周期性的大陆淹没有关，大陆架和陆表海的生态位不断扩大和缩小。
化石记录显示，生物多样性在地质时期呈准周期性波动。然而，生物多样性循环的因果机制仍然无法解释。

Abstract: The fossil record reveals that biotic diversity has fluctuated quasi-cyclically through geological time. However, the causal mechanisms of biotic diversity cycles remain unexplained. Here, we highlight a common, correlatable 36 ± 1 Myr (million years) cycle in the diversity of marine genera as well as in tectonic, sea-level, and macrostratigraphic data over the past 250 Myr of Earth history. The prominence of the 36 ± 1 Myr cycle in tectonic data favors a common-cause mechanism, wherein geological forcing mechanisms drive patterns in both biological diversity and the preserved rock record. In particular, our results suggest that a 36 ± 1 Myr tectono-eustatically driven sea-level cycle may originate from the interaction between the convecting mantle and subducting slabs, thereby pacing mantle-lithospheric deep-water recycling. The 36 ± 1 Myr tectono-eustatic driver of biodiversity is likely related to cyclic continental inundations, with expanding and contracting ecological niches on shelves and in epeiric seas.
