与仅从当代谱系获得的信息相比，使用化石记录可以更详细地重建进化过程。在这项工作中，我们不仅提出了物种形成和灭绝的随机过程模型，还提出了化石发现的模型。接下来，我们推导出一个明确的公式，用于用化石重建系统发育的可能性，该公式可用于估计物种形成和灭绝率。最后，我们提供了基于比较模拟的评估，对来自完整系统发育（包括灭绝的谱系）、仅用当代谱系的重建以及用当代谱系和化石记录的重建来估计这些速率的准确性进行评估。结果表明，与仅考虑当代谱系相比，考虑化石记录可以更准确地估计物种形成和灭绝率。 (C) 2012 Elsevier Ltd. 保留所有权利。
Using the fossil record yields more detailed reconstructions of the evolutionary process than what is obtained from contemporary lineages only. In this work, we present a stochastic process modeling not only speciation and extinction, but also fossil finds. Next, we derive an explicit formula for the likelihood of a reconstructed phylogeny with fossils, which can be used to estimate the speciation and extinction rates. Finally, we provide a comparative simulation-based evaluation of the accuracy of estimations of these rates from complete phylogenies (including extinct lineages), from reconstructions with contemporary lineages only and from reconstructions with contemporary lineages and the fossil record. Results show that taking the fossil record into account yields more accurate estimates of speciation and extinction rates than considering only contemporary lineages. (C) 2012 Elsevier Ltd.
