Figure 15.33 Which of the following statements about common features of chordates is true? a. The dorsal hollow nerve cord is part of the chordate central nervous system. b. In vertebrate fishes, the pharyngeal slits become the gills. c. Humans are not chordates because humans do not have a tail. d. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.

Was the ancestor of all dinosaurs feathered or scaly? What character condition did you get? use the picture below.
n. Scientists have found one new fossil that is similar to Archaeopteryx. It is only the second fossil of its kind. It shows an animal that had a long-feathered tail and small teeth, like non-avian dinosaurs. But the animal also had flight feathers and wings, like modern birds. The fossil also shows a fused clavicle bone, which confirms the relationship between birds and dinosaurs because they are the only two groups with this characteristic. What is true about this scenario? It shows evidence of evolution. It shows evidence of widespread expression. It shows evidence of climate change. It shows evidence of causation.
According to the phylogeny below, which of the following statements is true? Branch point (common ancestor) Lungfishes Amphibians Mammals etrapod limbs Amnion Lizards and snakes Crocodiles Homologous characteristic Otriches +6 Feathers Hawks and other birds A. The most recent common ancestor of all the species shown had tetrapod limbs. B. Amphibians are more closely related to ostriches than they are to lungfish. ) The most recent common ancestor of amphibians and mammals had amnion but did not have four walking limbs. O D. Amnion evolved earlier that the evolution of tetrapod limbs. DE. Crocodiles are more closely related to ostriches than ostriches are to hawks and other birds. Tetrapods Amniotes Birds
Describe the radiation in vertebrate forms from phylotypic stage by focusing on three groups of vertebrates and then tracing the development of several homologous features in each group. Connect specific embryological structures in the phylotypic stage to divergent morphological structures in the adults of each of these groups. (Answer all questions, if possible)
Consider the cladogram representing most of the major classes of animals. Consider the point A in the cladogram. What characteristic(s) might be used to separate fish from the other animals following in the cladogram? hale symmetnical ancestor O Endoskeleton O Non-terrestrial O Four legs or supports O The presence of scales
Suggest and support a hypothesis for the view that segmentation evolved in three different animal clades.
In the frog embryo, convergent extension elongates the notochord. Explain how the words convergent and extension apply to this process.
Fill in the blanks with synapomorphic, symplesiomorphic, or neither Mesoderm is a ___ feature of chordates, and a ___ feature of vertebrates, but mesectoderm (neural crest) is a ___ feature of chordates, and a __ feature of vertebrates
In a table, compare and contrast the generalized fish and generalized tetrapod skulls based on the three phylogenetically distinct parts of a vertebrate skull. Fish Skull Tetrapod Skull Chondrocranium Dermatocranium Splanchnocranium
of this =rab or ditions ionary escen- se or 5. Describe two examples of vestigial structures that you can find among the Caminalcules. These are structures that have been reduced to the point that they are virtually useless. Ear muscles and the tail bones are examples of vestigial structures in our own species. Explain how vestigial structures provide clues about a species' evolutionary past. Illustrate your argument with vestigial structures found in humans or other real species.
