新生代海洋动物生物多样性在属水平上的增加有高达 50% 归因于被称为“近期拉力”的抽样偏差，即通过对近期生物群相对完整的采样来扩大化石类群的地层范围。然而，在现存的 958 个有化石记录的双壳类软体动物属和亚属中，有 906 个出现在上新世或更新世。因此，近期的拉动仅占新生代双壳类多样性增加的 5%，双壳类多样性是海洋记录的主要组成部分，这表明多样性增加可能是一种真正的生物模式。
Up to 50% of the increase in marine animal biodiversity through the Cenozoic at the genus level has been attributed to a sampling bias termed "the Pull of the Recent," the extension of stratigraphic ranges of fossil taxa by the relatively complete sampling of the Recent biota. However, 906 of 958 living genera and subgenera of bivalve mollusks having a fossil record occur in the Pliocene or Pleistocene. The Pull of the Recent thus accounts for only 5% of the Cenozoic increase in bivalve diversity, a major component of the marine record, suggesting that the diversity increase is likely to be a genuine biological pattern.
