Underwater, whales produce loud noises: known as songs. Scientists use whale songs to study the movements for migrations, of groups of whales. Recently, scientists discovered something unusual: a single, solitary whale whose song is unlike that of all other known whales. The most notable difference between this unusual whale's song and those of other whales is its high pitch or frequency This unique whale is called the 52-hertz whale because it sings at the unusual frequency of 52 hertz, a much higher pitch than normal. When the 52-hertz whale was first detected, the cause of its uniquely high-pitched song was unknown; however, scientists now have several theories to explain it.
One theory holds that the 52-hertz whale may be a hybrid: the offspring of two different whale species Whales of different species are known to interbreed and produce hybrid offspring that combine characteristics from each of their parents' species. As a hybrid, the whale may have a unique song, different from that of either of its parents because it resulted from a combi nation of the two
A second theory is that the 52-hertz whale may have a damaged sense of hearing Just as people learn to speak by copying the sounds they hear, whales may learn to sing by listening to the sounds of other whales songs. When people are born deaf, their speech may sound different from that of people born hearing. Similarly, the 52-hertz whale’s songs may sound different simply because it cannot hear the songs of other whales.
A third theory holds that the 52-hertz whale may be the only known member of a rare species Perhaps there were once many more whales of this species, but most are now gone. It seems to be entirely unique only because most of its species has died out.
The reading states that there are three theories about the presence of 52-hertz whale which sings at an unusual frequency.The lecturer, however, finds the idea dubious and casts doubt on the reasons proposed by the reading passage.
The author argures that this whale can be the child of two different whale species, so its specific characters is the reslt of combination. Conversely, the lecturer brings up the idea that if the 52-hertz whale is the offspring of two seperate species it have to has a migration pattern alike other species. But the observation shows that it has its own unsual pattern which is different from others.
Furthermore, the reading passage holds the view that this unsual song may is the result of some damages occured for the whale and disabled it to hear others songs and prevents it to follow in that way. On the contrary, the professor underlines the fact that the high pitch relys on the physical structure of the throat. So the unsual songs do not depend on whale's problem in hearing others sound, because there is no connection between the hearing and throat structure.
Finally, the reading states that this whale may be the last member of its species and all the other members have died. In contrast, the speaker dismisses this issue due to the fact that the technology which scientists use in this days, have used many decades. As a result, if there were any other member of its species, they would have been detected, but no song have been heard before this one.
