Multispecies Coalescent

Discordance between individual gene trees   that share a phylogenetic history results from incomplete lineage sorting and   becomes increasingly likely when times between speciation events are short   compared with species’ population sizes. We provide a fully Bayesian   implementation of the multispecies coalescent that improves the accuracy and   precision of species tree reconstruction (Heled and Drummond 2010) and   divergence time estimation (McCormack et al. 2011).

多物种溯祖

共享一个系统发育史的多个单基因树之间的不一致性是由于不完全的谱系分类造成的,并且与物种的种群规模相比,当物种形成事件之间的时间较短时,这种不一致性变得越来越可能。我们提供了多物种联合溯祖的全贝叶斯实现,提高了物种树重建(Heled and Drummond 2010)和分化时间估计(McCormack   et al. 2011)的精准度。
