Underwater, whales produce loud noises, known as songs. Scientists use whale songs to study the movements, or 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 combination 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 presents three theories to explain the reasons why the 52-hertz whale is able to produce unique songs with high pitch and 52 hertz frequency. The lecturer, however, disputes these claims and provides counterarguments to each point made in the reading. Firstly, the reading argues that this whale may be a hybrid, which has combined characteristics of its parents of two different species. However, the lecturer challenges this notion of interbreed by explaining that during migration, hybrid whales tend to travel alongside non-hybrid whales. However, after observing the migrating locations of the 52-hertz whale, scientists were able to determine that it followed its own unusual migration pattern and traveled alone. Thus, it is unlikely that this whale is an interbreed. Secondly, the reading claims that the 52-hertz whale may have a damaged sense of hearing. By contrast, the lecturer counters this argument by stating that like humans, whales generate sound through throat. It is the vocal cord from which sounds originated. However, the 52-hertz whale’s unique sound indicates that its throat structure must be very special. So there is little connection between the unusual songs and born deafness. Lastly, while the reading emphasizes the possibility that the 52-hertz whale may be the member of a rare species, the lecturer points out that even if it is a member of a rare species, the 52-hertz whale must have parents, who also produced unique sound which would be heard by scientists. However, over decades of observations, there were no other sound have been heard like this one. Therefore, it rules out the possibility that this whale was came from a rare species. In conclusion, the lecturer considers that all the reasons presented in the reading are flawed, and the real cause of the sound remain mysterious.
