An important evolutionary innovation and a major difference between the limbs of extant lobe-finned fish and extant tetrapods is: Select one: 1. The presence of lobes on the fish fins. 2. Retention of fin rays in tetrapod limbs. 3. Limbs of tetrapods have associated muscles. 4. Limbs are supported by a single basal bone in tetrapods 5. Attachment of the pelvic limbs to the vertebral column via the pelvis in tetrapods. Please explain in detail the correct options as well as the incorrect options.

Explain how the following characters of modern frogs help with jumping locomotion. 1. urostyle and elongated pelvis: 2. Fused tibia+fibula and fused radius+ulna: d. What is the name of the rod-shaped structure present in the vertebral column of the modern anuran that consists of fused vertebral elements?
The following image is from a scientific publication by paleontologist Niel Shubin, who was part of a team who discovered the earliest known tetrapod, Tiktaalik. What does the image say about the bones in the fins of fish (on the left side) when compared to the bones in their tetrapod ancestors (on the right side)? (Image from Shubin et al., 2006). Gyptolepis Suriptens Eusthenopteron Panderichitys Tta Acanthostega erpelon Nothing can be concluded about the relationship They are analogous structures The structures are unrelated They are homologous structures
1. Briefly discuss the components of the shark’s vertebral column i.e. different sections, parts of the typical vertebra, and type of centrum. 2. Briefly discuss the basic components of the shark’s visceral skeleton. 3. Differentiate the basic parts of the shark’s pectoral girdle and pectoral fins with the pelvic girdle and pelvic fins.
Figure 29.3 Which of the following statements about common features of chordates is true? The dorsal hollow nerve cord is part of the chordate central nervous system. In vertebrate fishes, the pharyngeal slits become the gills. Humans are not chordates because humans do not have a tail. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.
Members of Chondrichthyes differ from members of Osteichthyes by having a _______. a. jaw b. bony skeleton c. cartilaginous skeleton d. two sets of paired fins
1. Observe the behavior of the live goldfish. Note the movement of the operculum. What is its function? Does a shark have an operculum? 2. Examine the model of the bony fish. Compare the fins, shape of the tail, scales and other external features with the shark. How do the fins of fish contribute to the evolutionary story of animals evolving to life on land? 1. Observe and compare the features of the amphibian specimens. 2. The frog will be used to review vertebrate anatomy. Begin by examining the thin skin of the frog. How does it compare to the skin of a reptile? Would the frogs skin help protect it against water loss? How is the frog able to supply its body tissues with enough oxygen even if there is some mixing of oxygenated deoxygenated blood? Amphibian, literally means “living on both sides”. Explain why amphibians have that name. What characteristics do reptiles have that make them more suited for terrestrial life than amphibians? Why are birds thought of as flying…
In what way do teleosts and other fish benefit from having a bony operculum? it prevents water outside of the body from flowing backward into the gills when the buccal (mouth) cavity is expanded it serves as a rotating joint that allows them to rapidly project their jaws forward more rapidly it forms a joint between the head and pectoral girdle and allow for a greater amount of head rotation it prevents the brain from being damaged by the lateral bending of fish attempting to escape from the mouth

Crayfish, unlike earthworms, do not have a hydrostatic skeleton. Instead, crayfish have a rigid exoskeleton. Give 2 advantages to the having the exoskeleton and 2 disadvantages.
How does the limb orientation of "advanced" tetrapods differ from that of "primitive" tetrapods? How much variation is there in the humeri, radii, and ulnas of tetrapods? What modifications has the manus undergone in the evolution of flight (birds, bats, & pterosaurs), swimming, running, & grasping?
_____1.A median ventral opening, posterior to the fusion of the two metapleural folds. ______2. the following are associated with bony fishes, except: placoid, cycloid, ganoid or ctenoid ______3. the typical turtle's body is cornified and provided with scales(true or false)
