Inferring reticulate evolutionary histories while accounting for incomplete lineage sorting

This week we will discuss a paper entitled "Maximum likelihood inference of reticulate evolutionary histories" by Yu and co-authors from PNAS. The paper presents a new method for inferring reticulate evolutionary histories while accounting for incomplete lineage sorting.

Abstract


Phylogenetic trees play a central role in biology, modeling evolutionary histories of taxa ranging from genes, to genomes, and to species. Although trees will continue to be an essential modeling tool in evolution, phenomena such as hybridization, or gene flow more generally, result in evolutionary histories that are best modeled by phylogenetic networks. Inference of such networks is complicated by the presence of other evolutionary events, such as incomplete lineage sorting (ILS). Here, we provide a maximum likelihood method for inferring reticulate evolutionary histories while accounting for ILS. The method enables new evolutionary analyses under more complex evolutionary scenarios than existing methods can handle.
