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 reading and the lecture are both about altruism which both human beings and animals have in common. The lecture contradicts the passage discussing altruism by example of meerkats.
First of all, the author of the reading illustrates altruism by providing example of meerkats. Sentinel meerkat which acts stand-guard with full stomach spectates while other members of group looking for food. It is mentioned that sentinel meerkats gives alarm to rest of the members which are obtaining food when some predators come and its hard to escape for the sentinel meerkats. The lecturer counters this idea by mentioning predator likely to attack in a direction away from cry of the sentinel so the statement in the passage that the sentinel is at greater risk is incorrect. The probability of the predator going after the group of meerkats which are hunt for food is at higher danger.
Secondly, narrator also covered altruisim in case of human beings. An example of donation of kidney has been considered. This example explains that it would not be correct to assert that the donor is an altruist and is not gaining anything out of the unselfishnes act he performs because he would not recieve appreciation from the society and experience the feeling of self-worth. Thus, in a way he recieves something non-material in exchange for a materialistic object.
