Phylogenetic Trees Made Easy, Fifth Edition leads the reader, step by step, through identifying and acquiring the sequences to be included in a tree, aligning the sequences, estimating the tree by one of several methods, and drawing the tree for presentation to an intended audience. Although aimed at molecular and cell biologists, who may not be familiar with phylogenetic or evolutionary theory, it also serves students who have a theoretical understanding of phylogenetics but need guidance in transitioning to a practical application of the methodology.
