WebShared characters that are a result of convergent evolution and not common ancestry are referred to as analogous characters. These analogous characters are not useful for … WebPhylogenetics Lab The objectives of this lab are: 1) to become proficient at interpreting phylogenetic trees, and to understand the evidence that is used to infer phylogenies 2) to gain experience in coding traits and using them to build phylogenetic trees. Part I: Interpreting trees and understanding the evidence used to infer trees.

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.
