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 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 animal are willing to sacrifice their food, or even their life, to assist other members of their group. The meerkat, which is a mammal that dwells 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 other hunt for food or eat food they have obtained. If a sentinel meerkat sees a predator such as a hawk approaching a group, it gives an alarm cry alerting other meerkats to run and seek shelter. By standing guard, the sentinel meerkat gains nothing- it goes without food while other eat and place themselves 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 lecturer talks about some important findings of a closely conducted research on the behavior of meerkats and expresses her opinion on human behavior. She contradicts these findings with the one stated in the passage related to altruism and provides reasons for her opposition to those points.
Firstly, the lecturer describes her finding about the meerkat's eating habits. Meerkats most often eat before they stand guard and act as a sentinel while others in the group are hunting out for food. Also, the meerkat stands guard near its burrows. In case of any predator approaching a meerkat, it gives an alarm to other group members and escapes quickly to its burrow. As a result, the sentinel is at minimal danger of being attacked by its predators. This finding contradicts with the one stated in the passage as its claims that the sentinel in a group of meerkats is in grave danger when a predator hunts them as it has to protect other members in the group. Such a behavior is selfish in nature and is against the theory of altruism.
Secondly, the passage states that the sentinel has to flee alone after giving an alarm cry. But the lecturers finding is in contradiction with the one stated in the passage. When there is an alarm cry given by the sentinel, meerkats either run away or gather themselves together to protect each other. As a result, there are lesser chances for the predator to attack a group of meerkat. Hence, the sentinel of the meerkat actually is not in grave danger of being hunted by its predator as other meerkats can protect the guard in case of an alarm cry.
Finally, apart from meerkat behavior that lectures also talks about human behavior. She considers a case of kidney donation from one human to another. The passage states that sacrificing one needs for others is altruism. But when a human donates a kidney to another, the donor can receive accomplishment from the receiver and hence, increase the donor’s self-worth. Such non-materialistic gains are contradictory to the concept of altruism as stated in the passage.
