Evolution of the Vertebrates Exercises 301 Latimeria, a modern sarcopterygian coelacanth living near Madagascar. Note the similarity of the tail to that of Eusthenopteron fossils in the previous figure. The tail is very different from that of the ray-finned fishes. This example is about 2 m long. (From Levin, H., 2013, The Earth Through Time (10 edition), figure 12-75, p. 370. This material is reproduced with permission of John Wiley & Sons, Inc.) 55. Compare the shape of the tail...
Discuss the major transformations in the digestive system of the vertebrates from the agnathan fishes to mammals. Give one unique functional anatomical trait of the digestive system in Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia. Try to relate this anatomical trait biology of each taxon. For example, why do birds (Aves) have a gizzard?

Regarding studies in early development of vertebrates (frog and mouse): A) What do you think is the most striking similarity between the way these organisms specify their anterior structures? B) What do you think is the most striking difference in the way these organisms specify their anterior structures? C) What are the similarities and differences between these mechanisms and the way that Drosophila specifies its anterior/posterior structures?
Do you think bacteriophages are likely to be more or less diverse than prokaryotes? Than eukaryotes? Why? Is a plaque the result of the lytic or lysogenic pathway of the phage lifecycle? Explain. Why were you instructed to make three dilutions of the phage in this experiment? What purpose does this serve the experiment?
Type an essay on Do you want the population of software developers to become more diverse? Why or why not? If you think it would be good, what are the barriers to making that happen? If you don't think so, how would a more diverse future affect you? 350-500 words
Which staffing processes do you think are most important? Why?
Why do you think some animals have a myogenic heart (self-excitable found in Vertebrates and some Mollusks like cephalopods) while others have a neurogenic heart (controlled by nerve impulses from the brain found in Annelids, and Arthropods)? Explain your reasoning. Lungfishes have a rudimentary air sac they use when their environment temporarily becomes anaerobic. How do you think their circulatory system is different from other fish? Construct a drawing to emphasize your view. In giraffes, the head could be up...
