Altruism is a type of behavior in which an animal sacrifices its own interest for that of another animal or group of animals. Altruism is the opposite of selfishness; individuals
performing altruistic acts gain nothing for themselves.
Examples of altruism abound, both among humans and among other mammals. Unselfish acts among humans range from the sharing of food with strangers to the
donation of body organs to family members, and even to strangers. Such acts are altruistic in that they benefit another, yet provide little reward to the one performing the act.
In fact, many species of animals appear willing to sacrifice food, or even their life, to assist other members of their group. The meerkat, which is a mammal that
dwells in burrows in grassland areas of Africa, is often cited as an example. In groups of meerkats, an individual acts as a sentinel, standing guard and looking out for
predators while the others hunt for food or eat food they have obtained. If the sentinel meerkat sees a predator such as a hawk approaching the group, it gives an
alarm cry alerting the other meerkats to run and seek shelter. By standing guard, the sentinel meerkat gains nothing—it goes without food while the others eat, and
it places itself in grave danger. After it issues an alarm, it has to flee alone, which might make it more at risk to a predator, since animals in groups are often able to work together
to fend off a predator. So the altruistic sentinel behavior helps ensure the survival of other members of the meerkat’s group
The article introduces the topic of altruism which is an act of unselfishness. More specifically, the author discusses that when a person performs altruism, he does not get anything in return for the act. On the contrary, the lecturer in the recording disagrees. She believes that there is no act without self-interest and when a person does something for others, he always gets something in return.
In the reading, the author uses an example of meerkats, a species of mammal, which show altruism. There is a sentinel among meerkats which guard others from predators during searching food. The author claims that the sentinel sacrifices eating food for guarding others. The lecturer, however, disagrees. She states that, according to a recent study, sentinel actually eat its meal before guarding others. So the assumption of the author does not hold true.
Another reason why the author feels that sentinel is performing altruism sacrificing its own interest is that, when predators comes to attack the meerkats, the sentinel alerts all of them but as a consequence, gets the least time to escape. Again, the lecturer believes that there are flaws in this assumption. According to her, as the sentinel notices the predator first, it gets the most amount of time to escape. Allso, the predator attacks the large group of meerkats who were eating, so the sentinel can escape easily.
The author also claims that, when a person donates kidney for others, he does not get anything in return. The professor in the listening is doubtful about that. She says that when a person sacrifices something for others, he gets appreciation from the society and feels a sense of self-worth. So accordin to her, the person donating organs actually get something in return.
To sum up, both the writer and professor hold conflicting views about altruism. the writer claims that altruism does not gain any benefit for the person who does it, whereas, the professor believes that there is no act without self-interest and the person actually gets something for his action in return.
