Both the lecture and the reading attempt to give an explanation about how humpback whales are able to migrate for long distance for feeding and mating purposes. The lecturer thinks that the explanations given by the reading are not convincing as explained by the followings.
First, the reading suggests that the high degree of brain complexity of these mammals makes them able to use stars to navigate by. The lecturer instead points out that this thesis is not convincing. In fact, he notes that similarly to humpback whales other medium-intelligent animals such as some birds have the same ability to migrate and orientate for long distance. Therefore, he suggests that a particular born instinct is more likely involved in the phenomenon of long-distance migration than an exceptional system of cognitive ability as the lecturer contends.
Second, the reading makes an argument based on the observation about the way they migrate. It explains that just as some birds maintain movement in a straight direction using physical landmarks, so do humpback whale using the star as a reference point for their long-distance migration. In contrast, the lecturer gives another explanation, according to him, thanks to an organ called magnetite, these animals are sensitive to the earth magnetic field, therefore, is this external force that guides the humpback whales’ migration.
Third, the lecturer excludes that the behavior of spy-hopping is used by humpback whales to emerge and look at the night sky for orientation. He rebuts by saying that this behavior has also been observed in sharks, and it is known that sharks do not migrate but they use spy-hopping to identify their preys. In addition, spy-hopping has been observed in humpback whales during the day too, when the stars are not visible. According to these observations, the lecturer contends that the spy-hopping argument made in the reading is pure speculation.
