Tree of Life Help The Tree of Life is a collection of WWW pages
illustrating the phylogenetic (or evolutionary) tree of
organisms, and presenting information about the characteristics
of thousands of different groups of organisms. Each ToL page
focuses on one particular group. At the top, there will usually
be a few pictures of representatives of this group, followed by
a phylogenetic tree or taxon list for the subgroups contained
within the current group. The tree or taxon list is also one of
the principal means of navigation along the branches of the Tree
of Life: it has links to deeper parts of the tree (toward the
root) and to finer parts of the tree (toward the tips). Below
the tree may be various topics, including an introduction to the
group, characteristics of members of the group, internet and
literature references, etc. At the top of each page, we provide
links to the major sections of the ToL web site, while the right
sidebar contains links to other pages within the current section
of the ToL web s
