2. Figure 1 Haeckel's phylogenetic tree of the animal kingdom.
This tree was devised by Ernst Haeckel in Most of the groups/phyla are familiar today yet our understanding of their relationships has changed dramatically in many cases. Illustration from: Ernst Haeckel (1866) Generelle Morphologie der Organismen (Berlin: Georg Reimer).

3. Figure 2
Current best estimate of the relationships of the animal phyla.
The diploblasts are shown in pink, the deuterostomes in red, the lophotrochozoans in blue and the ecdysozoans in green. Five problematic taxa are shown in black in their most likely positions. Much of the structure of the tree remains unresolved.
