The reading passage and the lecture both discuss the abnormal songs of whales, naming 52-hertz whales. In the reading part, the author mentions that there are several hypotheses which are tried to explain the possible reasons for this unusual song. however, in the listening part, the lecturer challenges what the author states and rebuts the reasons, citing that scientists are flawed to explain it, and it has remained a mystery until now. To begin with, as mentioned in the article, the author sets forth that the sounds exist because two different species of whales produce the offsprings, combined with two gens. Nevertheless, the speaker refutes the reason asserting that similar hybrids, which are produced because of the mating of two different whales, have their parents’ pattern of migration. however, it was not proved for 52-hertz whales since they have unusual patterns of migration rather than other whale species. Indeed, they migrate alone. Secondly, the author points out that they might be deaf as humans that when they are born deaf, they cannot produce sounds similar to other humans. Nonetheless, the speaker flatly contradicts the idea and contends that these kinds of whales have high pitch, and its signs are indicated on their physical structure of ears too. they have vocal apparatus like humans, which is not shown any damage. Hence, there is no connection between the deaf and the production of the sounds. Finally, the author claims that they have not been rare in the past, and they are maybe a new species, which is near to extinction. In contrast, the professor is of the opinion that scientists have listened to those unusual sounds over many decades, and if there were parents for these species, scientists would have noticed it. Actually, they have not been around before, since it is shown recently.
