Quantifying true patterns of biodiversity change over the Cenozoic has major implications for all of biology and paleontology but is still a source of significant debate. The problem centers on the magnitude and nature of several well-known sampling effects and analytical biases in the fossil record, including the Pull of the Recent. We test the effect of the Pull of the Recent at both generic and species levels on the exemplary New Zealand Cenozoic marine mollusk fossil record. We examine several biological traits of species to determine whether particular attributes of taxa control their likely presence or absence in the youngest fossil record (<2.4 Ma). We demonstrate that, for a tectonically active region, the Pull of the Recent does not exert a strong effect on apparent diversity patterns of genera and species over the Cenozoic at temporal scales typically used in global and regional biodiversity analyses. This result agrees with previous studies quantifying the effect of the Pull of the Recent in the marine and terrestrial realms at the genus level. The effect of the Pull of the Recent, although small, is greatest for the youngest fossil record (<2.4 Ma), particularly for species. This increase cannot easily be explained by effects related to shell mineralogical composition, size, habitat, taxonomic class, or lithification. The small effect that the Pull of the Recent exerts on the New Zealand molluscan fossil record implies that the apparent rise in regional marine diversity during the Cenozoic represents a true biological signal and/or reflects other confounding effects not considered here.

最近重新审视的吸引力：区域海洋化石记录中的物种水平影响可忽略不计

量化新生代生物多样性变化的真实模式对所有生物学和古生物学都有重大影响，但仍然是重要辩论的来源。问题集中在化石记录中几个众所周知的采样效应和分析偏差的大小和性质上，包括最近的拉力。我们在典型的新西兰新生代海洋软体动物化石记录上测试了属类和物种水平的近期拉动效应。我们检查了物种的几种生物学特征，以确定类群的特定属性是否控制它们在最年轻的化石记录（<2.4 Ma）中可能存在或不存在。我们证明，对于一个构造活跃的区域，在通常用于全球和区域生物多样性分析的时间尺度上，最近的拉动对新生代属和物种的明显多样性模式没有产生强烈影响。这一结果与以前的研究一致，这些研究在属水平上量化了近期拉力在海洋和陆地领域的影响。最近的拉动的影响虽然很小，但对于最年轻的化石记录（<2.4 Ma）来说是最大的，特别是对于物种。这种增加很难用与贝壳矿物组成、大小、栖息地、分类类别或岩化相关的影响来解释。
