title: Introduction to inferring evolutionary relationships.
abstract: This unit provides a general introduction to phylogeny. It defines common terms and discusses the issue of rooting trees, in addition to comparing gene and species trees. Methods for inferring phylogenies, such as distance methods, parsimony methods, and maximum likelihood are also presented. The unit concludes with discussion of how to assess tree confidence.
