In the lecture, the professor makes a series of points that cast doubt on all the arguments presented in the passage about the navigation of humpback whale by looking at stars. He states that navigation by stars are fascinating theory but all the evidences provided in the reading passage are not convincing.
First of all, the lecturer refutes the relationship between intelligence and navigation by stars. However, the author states humpback whales are highly intelligent ,thus, they are able to navigate by stars. But, the lecturer states birds and ducks are not highly intelligent animals but they use stars for navigation and they orientation. In fact, there is not real connection between being intelligent and be able to navigate by stars. It is just an instinct an animal to born with and do not have connected to the animal intelligence.
Also, the professor states there are other reasons for moving in straight direction for animals. Humpback whales have biomagnetic part in their brain that react to the earth magnetic field and this sensitivity to magnetic field could be their external object to stay in straight lines not looking at star.This contradict to the article's idea.
Lastly, the lecturer refutes the spy-popping as a reason for looking at star and navigation. He says that other animals like sharks use spy-popping for hunting their prey and they do not migrate. In addition, humpback whales do spy-popping during the day without any presence of stars. Therefore, spy-popping is not a reason for navigation and is just pure. speculation
