Education
Build trees from aligned sequences or a distance matrix with UPGMA, Neighbor-Joining and a small exhaustive parsimony search, then test them with bootstrap support. A "known truth" mode evolves sequences along a random tree so you can score each method by how well it recovers the real answer, and a rate-variation demo shows UPGMA failing where Neighbor-Joining holds up. Trees import and export as Newick, and a Robinson-Foulds comparison shows exactly which groupings two trees disagree on.
