ANIMAL COGNITION PHYLOGENETIC TREE
The Animal Cognition logo combines the tree of life with a neurological network. The tree of life
is drawn from current data obtained from the Tree of Life website. However, note that the
relationships between the taxa are subject to change (1,2).
In the below tree, all taxa starting with Porifera (Sponges) belong to the Animal Kingdom. Only Porifera (and possibly Placozoa, which are not very well understood) do not have nerve cells.
