1. Phylogenetic Trees Vocab
Phylogenetic Tree- a branching diagram that demonstrates the evolutionary history of a group of organisms.
Branch points- represents the divergence of two evolutionary lineages from a common ancestor.
Sister Taxa- groups of organisms that share an immediate common ancestor, therefore they are each other’s closest relatives.

2. Phylogenetic Trees Vocab
Clades/monophyletic group- includes an ancestral species and all of its descendants.
Outgroup- a species or group of species from an evolutionary lineage that is known to have diverged before the lineage that includes the species we are studying
Ingroup- the lineage we are studying.
Maximum parsimony- the simplest explanation (least evolutionary changes) that is consistent with the facts is the tree that is accepted
