Finally, it's important to note that in some instances, rectangular phylogenetic trees are drawn so that branch lengths are meaningful. These trees are often called phylograms, and they generally depict either the amount of evolution occurring in a particular gene sequence or the estimated duration of branches.

Evolutionary trees depict clades. A clade is a group of organisms that includes an ancestor and all descendents of that ancestor. You can think of a clade as a branch on the tree of life. Some examples of clades are shown on the tree below. ... ; Reading trees: Phylogenetic starbursts;

Molecular phylogenetic trees depict the relationships between gene sequences ... These trees use phylogenetic distance as the scale - measured in this case by the extent of sequence divergence in the small subunit ribosomal RNA sequences of the species. Notice that the lengths of the branches are uneven, because the rates...

In saying phylogenetic trees are estimates, I mean estimates in the formal statistical sense of estimation. The phylogenetic tree shown is the authors' best estimate of the phylogeny of the animals they studied, based on the characteristics they studied.

Regardless of how they are constructed, phylogenetic trees are usually governed by the Rule of Parsimony, a "simplest is best" precept which dictates that a family tree should contain no more than the minimum number of branch points necessary to accomodate all of the observed character states. Such a constraint...
