The passage represents a hypothesis as to how humpback whales are able to migrate long distances. The reasoning is explained to be their star navigation capabilities and a handful of observations are presented to support this reasoning. However the professor refutes all three of the observations made.
Regarding the relation between star navigation capabilities and intelligence, the professor uses the example of some birds to refute the claim. Specifically, he uses the example of the duck as an animal with only average intelligence that still employs star navigation. Thus, it would seem that there is no direct relationship between intelligence and star navigation.
Secondly, the professor disclaims that the reason humback whales travel in straight lines is because they use the starts for navigation. Instead, he points out to the fact that whales have a substance in their brain called biomagnetite that makes them sensitive to the earth's magnetic field. Therefore, he concludes that the reason they are able to move in straight lines is that they use the earth's magnetic field and not the starts as otherwise claimed by the passage.
Lastly, he addresses the spy-hopping behavior of humpback whales and mentions that this behavior is not, in fact, confined to humpback whales. Sharks, that are animals that do not migrate, exhibit this behavior as well but for a completely different reason (to spot their preys). Furthermore, humpback whales exhibit spy-hopping often during the day when the star can't be seen. Hence, one cannot really establish a link between spy-hopping and the whales' ability to migrate long distances using the star navigation hypothesis.
In conclusion, the professor completely disproves all of the points made in the lecture regarding the various supposed connections between the abilities and behaviors of the whales to star navigation, thus disclaiming that these observations can be used to support the star navigation hypothesis as an explanation for the whales' capabilities to migrate long distances.
