#Unit 9. Diversity of Life Forms
A phylogenetic tree is shown for the three
domains of life (Eukarya, Archaea, and Bacteria). The tree branches in two
directions from the first point, labeled Common ancestor of all life. One
branch leads in the direction of Eukarya and Archaea, and the other branch
leads to Bacteria. The branch leading to Eukarya and Archaea divide, one branch
leading to each domain. The branch leading to Eukarya divides into four
branches. One leads to Euglenozoans, and the other three lead to branching
points. The first leads to Forams in one direction, and another branching point
in the other that leads to Diatoms and Ciliates. The second branching point
leads to Red algae in one direction, and a branching point that leads to green
algae and land plants in the other direction. The third branching point leads
to amoebas in one direction, and a branching point that leads to fungi and
animals in the other direction. Land plants, Fungi and Animals are all
highlighted.
