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.
Here the lecturer has spoken about the altruistic behaviors of meerkats and of humans. She completely refutes the arguments presented in the passage.
First of all, the lecturer states that recent studies of meerkats have found that the sentinels standing guard actually eats before the group and thus refuting the point made in passage that sentinels are showing altruistic behavior.
Furthermore, the lecturer says that sentinels stand guard near a burrow and on seeing the predator they will be the first one to hide inside the burrow and reach safety. Also, when sentinels give out a warning cry, other meerkats will group together and thus draw attention of predator away from sentinal. Thus, again refuting the passage that sentinels are putting themselves in grave danger.
Lastly, the lecturer attacks the altruistic behavior of humans stated in passage by mentioning that the person donating an organ recieves appreciation from society and thus gain something from donating an organ, so the behavior is not at all altruistic.
