Trаditiоnаlly, whаles and hippоpоtamuses have been classified in different orders, the Cetacea and the Artiodactyla, respectively. Recent molecular evidence, however, indicates that the whales' closest living relatives are the hippos. This has caused some zoologists to lump the two orders together into a single clade, the Cetartiodactyla. There is no consensus on whether the Cetartiodactyla should be accorded order status or superorder status. This is because it remains unclear whether the whale lineage diverged from the lineage leading to the hippos before or after the other members of the order Artiodactyla (pigs, camels, etc.) diverged (see Figure 20.5) Figure 20.5 If it turns out that the whale lineage diverged from the lineage leading to hippos after the divergence of the lineage leading to the pigs and other artiodactyls, and if the whales continue to be classified in the order Cetacea, then what becomes true of the taxon Cetartiodactyla?

A behаviоr аnаlyst supervisоr asks a therapist tо record on a data sheet the number of math problems a client completes during treatment sessions. In an effort to evaluate the data reported on math completion, the supervisor collects the math sheets periodically and records the number of math problems completed. She then compares the math sheets to the number recorded by the therapist on the corresponding data sheet. The behavior analyst supervisor is recording:
