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 lecture and the article discussed the possible hypotheses for the song produced from the 52-hertz whale. The article suggested that there are three possible reasons that explain this founding. The lecturer, on the other hand, responded that all of the arguments mentioned in the article are weak without strong fundamental.
To begin with, the article stated that the 52-hertz whale might be a hybrid whale resulted from a combination of two different whales' species. The article illustrated that the unique song produced from the 52-hertz whale might generate from this unusual combination. However, the lecturer said that a hybrid theory is unlikely. He explained that the 52-hertz whale has very unusual migration pattern. According to the lecturer, if the 52-hertz whale is a hybrid whale, it should at least follow the other whales' migration pattern and migrate along with them.
Second, the article pointed out that the 52-hertz whale might have lost hearing sense. In contrast, the lecturer countered that the damages hearing sense's theory cannot explain the high pitch generated from the 52-hertz whale. The lecturer explained that high pitch sound depends totally on the throat structure, and it is not related to the hearing sense.
Finally, the article mentioned that the third possible hypothesis is that the 52-hertz whale is the only known member of very rare species. According to the article, this rare species could be entirely unique with unusual sound. The lecturer, on the other hand, claimed that the 52-hertz whale should at least has parents. Even though, the technology used to detect sounds in the oceans has been applied for long time, it has never heard song like this.
