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 term altruism defined as unselfish behavior that require sacrificing without getting anything back. According to the passage, altruism exits in many of humans and animals’ actions. However, the professor in the lecture emphasizes that there are no unselfish actions even when the expected reward is small or not obvious.
In the passage, the author gives an example about the altruistic behavior of meerkats, where one of the group stand as a guard while the others are eating or searching for food. The professor argue this point and cite a study on meerkats that says the one guarding eats before the others then it go to guard them. Thus, it doesn’t guarding out of selfishness.
Furthermore, the author state that this meerkat guard send an alarm to alert the others when a predator is approaching. While the study introduced by the professor contends that the meerkat guard will be the first one to see the predator, and also its crying alarm draw the attention of the predator away from him. Hence, he will be the first one to flee and the safest one, and he will not need to go far and can hide in a good nearby hideout.
Lastly, referring to a human example, the professor contends that a person who donate his kidney for anyone will still receive appreciation and he will gain self-worth of himself. So, donating an organism may look like altruism act, but in fact it is not.
