Hornets, spider wasps, ants, etc. This tree diagram shows the
relationships between several groups of organisms. The root of
the current tree connects the organisms featured in this tree to
their containing group and the rest of the Tree of Life. The
basal branching point in the tree represents the ancestor of the
other groups in the tree. This ancestor diversified over time
into several descendent subgroups, which are represented as
internal nodes and terminal taxa to the right. You can click on
the root to travel down the Tree of Life all the way to the root
of all Life, and you can click on the names of descendent
subgroups to travel up the Tree of Life all the way to
individual species.close box Ashmead, W. J. 1903. Classification
