Image: Five Kingdoms of Life
This
view represents Earthly life as composed of 5 kingdoms, 4 of which are
<!g>eukaryotic, and the 5th, the monera (what we now call <!g>prokaryotes) at the base
of the tree. This view of life is
based on structural and functional analyses of organisms, and a proposed
evolutionary line in which life moved from simple to more complex, and smaller
to larger.
