The reading and lecture both discuss about whether humback whales navigate by the stars. While the reading argues that whales actually orient themselves by looking at the stars and provides some evidence for this claim, the lecturer refutes this, stating that these reasons are irrelevant.
First of all, the passage suggests that humback whales’ high intelligence proves of the fact they can navigate by the stars. It notes since humback whales’ brains are well-developed, they can actually observe the stars for orientation. The lecturer opposes this point by arguing there is actually no connection between animals’ cognitive developments and their ability of navigating by the stars. It was also mentioned that birds also orient themselves by looking at the stars, but their brains are, in fact, average. Therefore, animals’ brains complexity is not connected to their ability observe stars for directions.
Secondly, the article argues that the fact humback whales form lines while migrating indicates their observation of stars for orientation. It notes that this movement is only possible if there are external objects by which these whales orient themselves-the stars. However, the lecturer posits that there other ways of analyzing this behavior. He explains that these whales move in straight lines because they are sensitive to magnetic field. According to him, there is an area in the whales’ brains which react strongly to these stimuli and thus, help them determine the directions. In other words, the humback whales orient themselves by magnetic field.
Finally, the passage points out that humback whales often conduct spy-hopping, in which they point ther heads upward as if to observe. It states the humback whales spy-hopped in order to observe stars. The lecturer challenges this point by mentioning the fact that some sharks also do spy-hopping but they do not orient themselves by the stars, but by their preys instead. In addition, humback-whales only spy-hopped during daytimes, when the stars can not be seen, so it is not logical to say that they do so to observe stars for directions.
