This page is a
Tree of Life Leaf Page.
Each ToL leaf page provides a synopsis of the characteristics of
a group of organisms representing a leaf at the tip of the Tree of Life. The
major distinction between a leaf and a branch of
the Tree of Life is that a leaf cannot generally be further
subdivided into 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.
