- Describe the structural differences between the pleopods and the pereiopods up the prawn. What hypothesis can you make regarding the functional use of pleopods by comparison? Pleopods of prawns are far larger in comparison to body size than crayfish. What might this tell you about their use between the two closely related animals?Describe three important differences between the skeletons of the crayfish and the pig.In vertebrates, what anatomical structure partially or completely replaces the notochord? 1.) lateral-line system 2.) cartilage or a bony skeleton 3.) endostyle 4.) dorsal hallow nerve cord
- Describe the structural differences between the pleopods and the pereiopods up the prawn.What hypothesis can you make regarding the functional use of pleopods by comparison?Pleopods of prawns are far larger in comparison to body size then crayfish (see drawings below).What might this tell you about their use between the two closely related animals?What is the taxonomic name for the superclass (of bony fish) that reflects the presence of a bony skeleton?Amphioxus long has been of interest to zoologists searching for a vertebrate ancestor. Explain why amphioxus captured such interest and why it no longer is considered to resemble closely the direct ancestor of the vertebrates.
- Compare and contrast the exterior anatomy of the pig to the shark and the lamprey. What has changed? What has stayed the same? What are the benefits of these changes?In terms of the differences between the opossum, bird, bat, and mole skeletons, which is most like the human (and therefore, most primitive or generalized)? Which is least like the human and, therefore, the most specialized?Explain How will you compare and contrast the skeleton of fishes and tetrapods?
- How does the alligator snout become elongated relative to the salamander’s? Does it add new bones, or change the shape of pre-existing (in amphibian ancestors) bones?Give an example animal for some of the key adaptations of chordates: (a) backbone, (b) skull, (c) amniotic egg, (d) bony skeleton. Choose a different animal for each adaptation.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
