The evolutionary tree of living things is currently supposed to run something along the lines of that listed below. Most of the above tree was based on ideas from
cladistics; where more than two groups are shown in a single branch, there is disagreement about how they diverged. Hypothetically
taxonomy would follow the tree whenever possible, but it many places it does not at present.
