WebPhylogenetic Tree Terminology: • Node: represents a taxonomic unit. This can be either an existing species or an ancestor. • Branch: defines the relationship between the taxa in terms of descent and ancestry. • Topology: the branching patterns of the tree. • Branch length: represents the number of changes that have occurred in the branch.
