There is no relationship between environmental stability [as indicated by infaunal (stable) versus epifaunal (unstable) habits] and the generic duration of extinct marine bivalve mollusks when the effects of cosmopolitanism (which is associated with long generic durations) and other paleontological "noise" are excluded. This is contrary to the "depauperate gene pool" hypothesis of extinctions.
当排除广布种（与较长的属级延续时间相关）和其他古生物学“噪声”的影响时，环境稳定性（如内栖[稳定]与外栖[不稳定]习性所示）与已灭绝海洋双壳类软体动物的属级延续时间之间没有关系。这与灭绝的“基因库贫瘠”假说相反。
