There is some discrepancy between the author and the lecturer over the issue of whether humpback whales use stars to navigate during migration or not. The author of the passage believes that they do use stars to travel long distances, while the lecturer thinks otherwise.
First of all, according to the lecture, the usage of starts for navigation by humpback whales can be explained by the fact that they have more complex brains. It is mentioned that they are intelligent enough to be able to use stars. Conversely, the lecturer states that intelligence has nothing to do with the use of stars due to the fact that ducks, which also use stars to migrate, are not really intelligent. He continues by saying that there is no connection between the use of stars and overall intelligence. Clearly, the author and the lecturer maintain different views on whether intelligence is connected to navigation by the usage of stars or not.
The second point author makes is that humpback whales migrate in straight lines and animals need an external object or force to be able to orient themselves during long distance travels. The passage notes that unlike birds, humpback whales can only use stars as an external object. The lecturer, however, introduces the idea that humpback whales have biomagnetants, which lets animals sense magnetic fields of the earth. Furthermore, he says that humpback whales might be using these magnetic fields instead of stars to orient themselves during migration.
Lastly, the author explains how humpback whales display a behavior called spy-hopping that is rarely seen among marine animals. The article establishes that humpback whales might be doing this to look at stars in order to navigate. On the other hand, the lecturer rebuts this argument by suggesting that despite being rarely seen among sea animals, this behavior is also demonstrated by sharks and they use not to navigate but only to hunt. He also puts forth the idea that humpback whales display this behavior even when there are no stars to be seen in the sky. Basically, the lecturer argues that sky-hopping has nothing to do with the use of stars during migration.
In conclusion, the lecture effectively casts doubt on all of the claims and theories presented in the reading.
