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 listening content totally contradicts the reading passage on the concept of altruism from humans and animals.
To begin with, the reading says that meerkats eat nothing while standing guard. But the speaker argues that meerkats eat before standing guard and are full of stomachs when they are on duty for their group. Besides, the reading talks about the fact that the sentinel meerkats put themselves in danger because of giving alarms and running alone without protection. However, the lecturer defends that they are close to burrows, they can escape and hide in the burrows faster than other meerkats as soon as they see the predators, so they are actually safe. Moreover, they are also safer when they give out the alarm cry because other meerkats will get together or move quickly. This will draw the predator’s attention and increase the caller’s chance to survive.
Lastly, the reading mentions that humans can share food with or even donate their organs to strangers without anything in return. Yet the lecturer disputes that people who do these still gain some non-material rewards, such as appreciation from society. Whatever they do can increase their own degree of self-worth. Therefore, the passage and the lecture are controversial on the issue of altruism.
