If cetaceans are determined to have diverged from the lineage leading to the artiodactyls before the divergence of lineages leading to the modern artiodactyls (including hippos), then the cetaceans can be considered1. a sister order to the order Artiodactyla.2. an ingroup of the order Artiodactyla.3. the common ancestor of the order Artiodactyla.
