Passage:

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.

Listening Script:

You know, often in science, new findings force us to re-examine earlier beliefs and assumptions.

And a recent study of meerkats is having exactly this effect. The study examined the meerkat’s behavior quite closely, much more closely than had ever been done before. And some interesting things were found . . . like about eating habits . . . it showed that typically meerkats eat before they stand guard—so the ones standing guard had a full stomach! And the study also found that since the sentinel is the first to see a predator coming, it’s the most likely to escape . . . because it often stands guard near a burrow, so it can run immediately into the burrow after giving the alarm.

The other meerkats, the ones scattered about looking for food, are actually in greater danger. And in fact, other studies have suggested that when an animal creates an alarm,the alarm call might cause the other group members either to gather together or else to move about very quickly, behaviors that might actually draw the predator’s attention away from the caller, increasing that animal’s own chances of survival.

And what about people—what about some human acts that might be considered altruistic? Let’s take an extreme case, uh, suppose a person donates a kidney to a relative, or even to a complete stranger. A selfless act, right? But . . . doesn’t the donor receive appreciation and approval from the stranger and from society? Doesn’t the donor gain an increased sense of self-worth? Couldn’t such non-material rewards be considered very valuable to some people?

Que: Summarize the points made in the lecture you just heard, being sure to specifically explain how they cast doubt on points made in the reading.

The reading states that altruism is a type of behavior by which humans or animals exhibit selflessness by sacrificing themselves for the benefit of others. On the other hand, the lecturer suggests that the animals or humans cannot be classified as completely altruistic. The lecturer casts her doubt on the main points of the reading by providing two reasons.

First of all, according to the reading, meerkat is taken as an example to emphasize the altruistic behavior among animals. The sentinel/standing guard is portrayed as an individual which looks out for predators while other animals hunt or eat the food they had obtained. The standing guard is described as the one who risks its life to save the rest of its group from the predators. However, the lecturer disputes this belief by quoting a recent detailed analysis of the meerkat's behavior. She mentions that the standing guard feeds well before it starts to guard and consequently, it gains more energy to escape from the predator compared to the rest of the group. Furthermore, she states that, since the standing guard detects the predator prior to the rest of the group, it has more chances to escape quicker than the rest of the group.

Secondly, the reading notes that humans are altruistic when they donate body organs to family members or even strangers. Whereas, the lecturer disagrees with this statement. She points out that organ donation might be a selfless act but the donor will receive appreciation and recognition which will increase his/her self worth. She further talks about how some people consider non material rewards more valuable.

In conclusion, the lecturer is in disagreement with the reading about altruism and effectively challenges the points made by it.
