This page is a
Tree of Life Branch Page.
Each ToL branch page provides a synopsis of the characteristics of
a group of organisms representing a branch of the Tree of Life. The
major distinction between a branch and a leaf of
the Tree of Life is that each branch can be further subdivided into
descendent branches, that is, subgroups representing distinct genetic
lineages.
For a more detailed explanation of the different ToL page types, have a look at the
Structure of the Tree of Life page.
