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 passage discusses several causes that might have led to the little ice age. However, the speaker in the lecture casts doubt on the claims made in the article. he mentions that the arguments in the article are outdated and new information simply disproves all of them.
First and foremost, the author believes that the disruption of the gulf stream by the melting glaciers could be the reason behind the drop in earth's temperature. The lecturer, on the other hand, points out that if this was the case, the decrease in temperature should have been observed only in Europe and North America. On the contrary, the cooling effect affected the southern hemisphere too, such as new Zealand and South Africa. Thus, this hypothesis could not be true.
Secondly, the writer argues that volcanic activity could have sent dust into the atmosphere, which, in turn, would have blocked sunlight and decreased global temperatures. In contrast, the lecturer brings the fact that people at this time did not report any visual effects, which are expected under these circumstances, such as a colored sun or brown snow. Hence, this argument lacks coherence.
Lastly, the author contends that the decline in human population during this era allowed more trees to grow in forests and as a result, these trees absorbed most of the carbon dioxide, which is the greenhouse gas responsible for keeping the earth warm. The lecturer challenges this proposal. he holds that there was not enough time for this to happen as the human population started to regrow fairly quickly cutting down trees and clearing up forests for agriculture. Consequently, the trees were not there long enough to cause a cooling effect on earth.
