The document involves constructing a maximum parsimony tree for an aligned DNA sequence dataset of three species and an outgroup. It requires mapping all nucleotide changes, identifying synapomorphies that support the tree, and noting any autapomorphies and homoplasious characters. Additionally, it specifies treating Z as the outgroup and handling homoplasies as reversals.

1. Practice Parsimony Tree Building Below is an aligned DNA sequence dataset for three species
and their outgroup. Draw the maximum parsimony tree for this dataset with all nucleotide
changes mapped onto it. Assume Z is an outgroup! Map any homoplasies as reversals. What
synapomorphies support this tree? What are the autapomorphies in the tree? What are the
homoplasious characters (if any)?
