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 article explaines about altruism, A type of behaviour in which an animal sacrifices its own interest for that of another animal or group of animals. However, the professor opposes this fact and gives examples for the altruistic behaviour of both animal as well as humans.

First, In the example of meerkats, the reading claims that an individual acts as a sentinel, standing guard and looking for predators while others hunt for food. The professor refutes this point by saying that the meerkat gaurds always have their stomach full. So the claim made about the meerkat guard goes without food is not true. In addition reading states that the meerkat guard also protects the others in a group by watching for predators and places itself in the grave danger. The professor also disagrees with this by saying that the guard always stands near to burrows. So whenever meerkat guard sees any predator, it makes the alrming cry and after that it can hide inside the burrows. While other meerkats in the group are more vulnerable of being hunted as the are in group and they might attract predators towards them.

Second, About the human's altrustic behaviour, the articles states that, unslefish acts of humans include sharing foods, donations or body organs to family members without any rewards. The professor opposes this point and says that when a person donates kidney to their family or friends, eventhough they dont get any actual reward, but they always get appreciation from friends and society. and by donating food or cloths the person always feel a sence on self satisfation. Hence, The professor explains that the individuals who perform altrustic acts and gain nothing is actually not correst.
