Abstract Details

2021, Doctor of Philosophy, Ohio State University, Statistics.
Inference of the evolutionary histories of species, commonly represented by a species tree, is complicated by the divergent evolutionary history of different parts of the genome. Different loci on the genome can have different histories from the underlying species tree (and each other) due to processes such as incomplete lineage sorting (ILS), gene duplication and loss, and horizontal gene transfer. The multispecies coalescent is a commonly used model for performing inference on species and gene trees in the presence of ILS. This thesis introduces Lily-T and Lily-Q, two new methods for species tree inference under the multispecies coalescent, and sets a framework for generalizing the Lily procedure to allow for differing mutation rates on different branches of the tree. Lily-T and Lily-Q are then compared to two frequently used methods, SVDQuartets and ASTRAL, using simulated and empirical data.
