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 Edmontousaur's were migrating during the winter because of the lack of the food supplies, while the lecturer claims that the reading passage states is not convincing and disputes those reasons presented in the reading passage by several proofs.
First, the writer claims that Edmontousaur diets was just based on the vegetation and lack of the plants growing because of the cold weather. Force Edmontousaur to migrate to the hospital places in the winter. However, the lecturer views to this issue from an opposite angle. According to the speaker, summers in the arctic reigns were warmer and hospital than now and support good vegetation growth, although vegetation die in the winter. Edmontousaur could easily use those plants nutrients during the cold seasons.
Second, the belief in the reading passage is that Edmontousaur were living in herd and based on the observation on the modern animals. Most of the animals which lives in herd, have migrate lifestyle, while the lecturer refutes this view point and says those animals’ life in groups to protect themselves from the predators give rose elk as an example which lives in a group, but don't migrate.
Additionally, the reading passage states that the Edmontousaurs had capable to migrate long distance. By contract, the professor demonstrates a different idea that just adult Edmontousaurs had this capable not juvenile ones, so Edmontousaurs could left their youngest alone during the migrate because they can't live by themselves. Vividly they didn't migrate.
All in all, the professor clearly identifies the weaknesses in the reading passage reasons and convincingly shows that the central point in the reading passage, the idea about the Edmontousaur migration, is actually incorrect.
