Large numbers of dinosaur fossils have been discovered in deposits on Alaska's North Slope, a region that today experiences an extremely cold, arctic climate. One hundred million years ago, when those dinosaurs were alive, the environment of the North Slope was already inhospitable, especially during the winter when it experienced several months of total darkness. How did the dinosaurs survive the wintertime? Paleontologists have proposed that one of the most common North Slope dinosaurs, the elephant-sized edmontosaur (Edmontosaurus), survived the winter by migrating south to more hospitable regions. Several arguments support the migration hypothesis. First, the edmontosaur's diet supports the migration hypothesis. Edmontosaurs fed exclusively on plants. Since there would have been no plants growing during the cold and dark North Slope winter, it appears that the edmontosaur must have left for at least part of the year and migrated to more temperate zones to find food. Second, many edmontosaur skeletons have been unearthed from the same site. This suggests that edmontosaurs lived in herd. Many modern-day migratory animals, such as caribou and buffalo, live and migrate in herds as well. Moving in herds helps animals coordinate their migration. The finding that edmonotsaurs lived in herds further supports the migration hypothesis. Finally, edmonosaurs were physically capable of migrating long distances. To reach more hospitable regions, the edmontosaur had to migrate about 1,600 kilometers southward. To make such a journey, the edmontosaur needed to move at about five kilometers per hour for several weeks, which is certainly could do. These animals could run very fast, reaching speeds up to 45 kilometers per hour. It could have easily used its locomotive power to move to warmer climate during the harsh arctic winters
In the reading passage, the author discusses three kinds of the reasons to illustrates that the Edmontosaurus were migrating to find the food supply beacause of the lack of the food sources in the arctic climate, while the lecturer claims that what the reading passage states is not convincing and disputes those reasons presented in the reading passage by several proofs.
First, the belief in the reading passage is that diets of Edmontosaurus shows that they were migrating because they need enormous vegetation supplies on their diets to live. Additionally, the climate in the winter not allow to any kind of vegetation to grow, while the lecturer refutes this claim by saying on that time climate on the Arctica were warmer than now besides the sun was shine for 25 hours and support the growth of vegetation, therefore, Edmontosaurus didn’t need to migrate to obtain better food supply in the winter.
Second, the writer claims that Edmontosaurus lived in herds and their skeletons were found in the different sites which shows the truth of the migration hypothesis. However, the lecturer demonstrates a different idea she says that animal lives in herd to protect themselves from predators and uses rozav elk as an example which lives in a herd, but don't migrate.
Third, the reading passage state that Edmontosaurus were physically capable to migrate. By contrast, the speaker views to this issue from an opposite angle. According to the speaker, just adult Edmontosaurus have the physical capability to migrate not juveniles and if Edmontosaurus live alone their young during the migration, youngest couldn't have lived just by themselves.
All in all, the professor clearly identifies weaknesses in the reading passage and convincingly shows that the central argument in the reading passage, the idea that Edmontosaurus were migrating in the winter to find the food supply, is actually incorrect.
