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.
Based on the set of material, the author contends that humpback whales migrates long distance by star, and proposes three main evidence. However the lecturer casts doubt on the information is presented and believes the presented information is not convincing enough.
First of all, the reading passage illustrates that humpback whales are smart enough to navigate by stars, however the speaker in the lecturer claims that there is no connection between intelligence and star navigation. He also use an example of duck, duck has the average intelligence but it will navigate by star. Thus star navigation is just an instinct of animals, in this way, the first point in the passage does not make any sense.
In addition, the writer demonstrates that humpback whales navigate in straight line in order to support the idea. Yet again, the professor in the listening refutes this opinion and posits that there is another reliable explanation about navigation in straight lines. The animals will feel the external force to keep navigating in straight line. In this case, the humpback whales have a bio-magnetic organ in their brains to feel the earth magnetic field to instruct their navigation path. Therefore, the second point in the reading does hold the water.
Despite the statement in the passage that spy hopping is another evidence to support main idea of the passage, the professor reputes that spy hopping is nothing to do with star navigation. Professor also take an instance of shark. Sharks will do the same behavior of spy hopping for choosing prey and sharks do spy hopping in the daytime which means there is no star visible. Hence, the third point is untenable due to professor's illustration.
