Most phylogenetic trees are rooted, meaning that one branch (which is usually unlabeled) corresponds to the common ancestor of all the species included in the tree. Note, however, that a tree can ...

Imagine that a mutation occurred in an individual belonging to a lineage on a phylogenetic tree, and that this mutation changed some visible aspect of the organism that carried it. For example ...
