Historically, whales and hippos have been classified in different orders: Cetacea and Artiodactyla, respectively. Recent molecular evidence, however, indicates that whales' closest living relatives are hippos. This has caused some zoologists to lump the two orders together into a single clade, the Cetartiodactyla. However, it remains unclear whether the whale lineage diverged from the hippo lineage before or after other members of Order Artiodactyla diverged. The cladograms below show these two possibilities. Considering only whales and hippos, which cladogram shows these two groups positioned in the same clade?
