The origin of extant neotropical biodiversity has been a controversial topic since the time of Darwin. In this review, I discuss the timing of, and potential driving factors associated with, diversification using recent evidence from molecular phylogenetics. Although these studies provide new insights into the subject, they are sensitive to dating approaches and targets, and can eventually lead to biased conclusions. A careful analysis suggests that the origin of extant neotropical biodiversity cannot be attributed to the action of one or few events during key time intervals. Rather, it is the result of complex ecological and evolutionary trends initiated by Neogene tectonic events and palaeogeographical reorganisations, and maintained by the action of Pleistocene climatic changes.
现存的新热带生物多样性的起源自达尔文时代以来一直是一个有争议的话题。在这篇综述中，我使用分子系统发生学的最新证据讨论了多样化的时间和潜在的驱动因素。尽管这些研究为该主题提供了新的见解，但它们对约会方法和目标很敏感，最终可能会得出有偏见的结论。仔细分析表明，现存的新热带生物多样性的起源不能归因于关键时间间隔内的一个或几个事件的作用。相反，它是新近纪构造事件和古地理重组引发的复杂生态和进化趋势的结果，并通过更新世气候变化的作用得以维持。
