在过去的十年里，利用系统发育数据估计多样化率引起了人们的广泛关注。在这方面，对不完全的亲缘关系（例如在科一级解决但在种一级未解决的亲缘关系）的分析仍然很困难。我在这里提出了一个基于可能性的方法，结合联合收割机部分解决的物种起源与分类（物种丰富度）的数据，以估计物种形成和灭绝率。这种方法是基于拟合的出生和死亡模型的系统发育和分类数据。该方法的一些例子与鸟类和哺乳动物的数据。该方法与现有的方法，处理不完整的遗传。本文介绍的方法的一些应用和推广作了进一步讨论。
The estimation of diversification rates using phylogenetic data has attracted a lot of attention in the past decade. In this context, the analysis of incomplete phylogenies (e.g. phylogenies resolved at the family level but unresolved at the species level) has remained difficult. I present here a likelihood-based method to combine partly resolved phylogenies with taxonomic (species-richness) data to estimate speciation and extinction rates. This method is based on fitting a birth-and-death model to both phylogenetic and taxonomic data. Some examples of the method are presented with data on birds and on mammals. The method is compared with existing approaches that deal with incomplete phylogenies. Some applications and generalizations of the approach introduced in this paper are further discussed.
