Trees as graphs Phylogenetic trees are a special case of what is known as a graph, in which a series ofnodesare joined byedges, known asbranches. Nodes are split into terminal nodes (or “leaves” to keep with the tree analogy), also known asOperational Taxonomic Units (OTUs)and internal...
A phylogenetic tree (commonly known as an evolutionary tree or a phylogeny) is a diagram with branches that displays the evolutionary relationships between different biological species.

Investigate the evolutionary origins of human immunodeficiency viruses (HIVs) using molecular phylogenetic tools. You will learn how to align sequences and build a phylogenetic tree, as well as how to view and manipulate the tree.
Split network showing the 14 genera of theLepanthesclade inferred from 3,000 tree replicates of the BI inference. The network shows well supported groups without uncertainty in the relationships. Full size image Character evolution ASR was based on the one-rate model ER that was consistently better...
Phylogenetic trees are central to a wide range of biological studies. In many of these studies, tree nodes need to be associated with a variety of attributes. For example, in studies concerned with viral relationships, tree nodes are associated with epidemiological information, such as location, ...
