- Identify skeletons of Indohyus, Ambulocetus, Dorudon and modern right whales.
- Compare and contrast the digits and auditory bullae of the species mentioned above.
- Explain the unique characteristics of the auditory bullae of cetaceans.
- Describe the basic anatomy of the vertebrate fore- and hind-limb; include names of all bones in the arm and leg.
- Explain which parts of the basic limb body plan are common to all vertebrates, at least in the embryo and fetus.
- Describe at least one vestigial trait in both cetaceans and humans.
- Describe the embryonic development of hind limbs in cetaceans.
- Describe how anatomical features of Indohyus, Ambulocetus, Dorudon and modern whales and dolphins correlate with ages of the fossils to suggest change through time.
- Explain how transitional fossils support the notion that species change through time using examples.
- Explain the concept of descent with modification.
- Interpret cladograms (phylogenies) using the concept of descent with modification.
- Give examples of transitional fossils in the cetacean lineage.
- Explain how pelycosaurs, cynodonts and modern mammals can be interpreted as transitional fossils.
- Describe transitional forms between dinosaurs and birds.
- Describe transitional forms between fish and amphibians.
- Explain how we compare species using DNA sequences.
- Explain how DNA and physical characteristics (morphology) of modern species and fossils relate to the fossil sequences of cetaceans discussed in the earlier portion of the lecture.
