Like many creatures, humpback whales migrate long distances for feeding and mating purposes. How animals manage to migrate long distances is often puzzling. In the case of humpback whales, we may have found the answer: they may be navigating by the stars, much as early human sailors did. What we know about humpback whales makes this a distinct possibility.
First, humpback whales seem to be intelligent enough to use stars to navigate by. Whales' brains have a high degree of complexity'a common determiner of intelligence. This suggests that the whales' brain power far exceeds that of most other animals. The whales' well-developed cognitive ability seems to provide a sound basis for the ability to use a complex, abstract system of sensory stimuli such as the night sky for orientation.
Second, humpback whales migrate in straight lines. Animals can maintain movement in a straight direction for long distances only if they orient themselves by some external objects or forces. Many birds and other terrestrial creatures, for example, use physical landmarks to help them stay on track as they migrate. Whales, which swim in the open ocean, cannot rely on land features; they could, however, rely on stars at night to provide them with external signs by which to maintain direction over long distances.
Third, humpback whales exhibit an unusual behavior: they are sometimes observed floating straight up for minutes at a time, their heads above the water as though they were looking upward. The behavior is known as spy-hopping, and it is very rare among marine animals. One explanation for the function of spy-hopping is that the whales are looking at the stars, which are providing them with information to navigate by.
On the basis of what I heard from the listening material and reading passage, I can clearly tell that the speaker is mainly talking why the speculation is not convincing in consideration of comparison from other animals and factors. This strongly challenges the point of views held by the narrator. Followed are the three aspects where the two materials diverge from each other.
First of all, the professor states that there is not a persuasive connection between the intelligence and the navigation. He takes the duck, which is a animal with average intelligence, for example, and points it out that ducks are able to navigate themselves. However, it contradicts the statement made by the author that humpback whale can navigate because they are smart enough. Later, the professor says that it is more like a instinct ability to do so, instead of a consequence of high intelligence.
Second, the professor argues that there might be some external forces, except for external signs, possible to make humpback whales queue as a long straight line. It is magnetite that the professor considers a feasible force to drive them line up. At the same time, humpback whales are not look upward for looking at stars. They do so since the effect of the magnetite. This argument provide another possible and viable reason to explain why humpback whale will line up, which is the viewpoints in the reading passage.
Third of all, the professor states that even the behavior is rare, there are still other species do so, such as shark. Hence, there is no a strong connection to point out the conclusion. Furthermore, they do so at day, not night. It is weird to contend they are doing so to watch stars.
In conclusion, the contentions mentioned in the material are jeopardized by the professor. He is fully opposed of what believed by the writer.
