The article and the lecture are about three theories which pretend to clarify the reasons for the extinction of a huge marine mammal known as Steller’s sea cow. The author in the passage believes that those hypotheses are not only well-supported but also have some evidence that may confirm this issue. However, the lecturer cast doubt on the statements made in the article. He thinks that those explanations present problems that not fit with the extinction of the sea cows.
First, the author claims that overhunting may have caused the decline of the sea cow’s population because they were a good source of food in a harsh environment. Nevertheless, this hypothesis is challenged by the lecturer who posits that due to the great size of these sea creatures and the low population of native Siberian people, it is unlikely that natives may need so much source of food which implies that this extinction could not have been produced by overhunting.
Second, the article states that the sea cow population began to decrease constantly until it became extinct because of the decline of the main source of food caused by ecosystems disturbances. Nonetheless, the lecturer discredits this idea by clarifying that if ecological changes had happened before the extinction of sea cow, it would have been affected other marine animals such as whales.
Finally, the author mentions that the arrival of European fur trades during the period in which sea cow became extinct may have caused the decline of their population since European trades possessed weapons that allowed them to kill these creatures easily. The lecturer, on the other hand, puts forth the idea that when European traders arrived at these areas, by then, the sea cow population was relatively so small. Therefore, the extinction of these marine animals was caused by another issue when the population was larger.
