The reading and the lecture are both about how animals manage to migrate long distances, specifically the example of the humpback whales, while using the stars as a guide. Whereas the author of the reading suggests that scientist might have find the answer, the lecturer states that this theory of the starts is fascinating but there is no relation between starts and navigation. The lecturer casts doubt on the main points made in the reading by providing three mainly reasons.
First of all, according to the reading, the author suggests that humpback whales seem to be intelligent enough to use stars to navigate because they have a well-developed cognitive brain. The author also mentions that the whales' brain power far exceeds the rests of the animals. However, the lecturer refutes this point. He says that there is no connection between the whale brain and intelligence. Additionally, he says that whales navigate by instinct, like other animals.
Secondly, the reading states that because whales swim in the open ocean, they cannot rely on land features to navigate in straight line, so they orient themselves by some external objects or forces, in this case the starts. Nevertheless, the lecturer disputes this idea by saying that the earth magnetic fields are the one who help whales get oriented, not the starts.
Finally, the reading claims that humpback whales exhibit an unusual behavior, known as spy-hopping, which is rare among marine animals and this behavior is what allow whales to look at the stars, which provide them with information to navigate. The lecturer, on the other hand, believes that this is pure speculation because whales navigate the whole day, not only at night using the starts as a guide.
