The article is about humpback whales and their ability to migrate. The passage explains that this ability is connected to stars, and provides three reasons of support. However, the professor believes that the humpback whales migration feature doesn't have a plausible connection to stars, and refutes each of the author's reasons.
First, the reading claims that this kind of whales have especial intelligent that enables them to navigate the way by stars. This point is challenged by the professor. He states that navigating by stars doesn't connected to animals intelligence; even though, those animals with this ability, such as some birds like ducks, do so based on their instinct. thus, connecting navigation through stars to intelligence is not appropriate.
Second, the author of reading posits that as hampback whales migrate in straight lines shows that they rely on stars at night in order to find their ways, because they need some external objects to follow. The professor, on the other hand, mentions that those animals that use objects to find their ways, actually send back and forth some signals that help them to do so. He elaborate on this point by saying that, as it is impossible to send a signal to stars and get the response, they probably use bio magnetic field to migrate in straight lines.
Finally, the author argues that hampback whales do spy-hopping to look at stars and navigate their path. The professor rebuts this point bay mentioning that this behavior is very rare among animals, and those who have this function, like sharks, use it to find their preys and hunting, not navigating. He also states that hampback whales do spy-hopping in the day, when the stars are not in the sky.
In conclusion, the professor effectively casts doubt on all the theories and claims presented in the article.
