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.
Passage talks about the altruistic behavior on the other hand lecture show that the behavior shown by animal or any human in certain circumstances are not altruistic behavior.
Passage gives two examples to describe the altruistic behavior. First one is about the Meerkats who guard to the other while they eat. For that, they have to sacrifice food or even their life. But, the lecture says that the Meerkats do not stand guard with the empty stomach, they usually eat food before they stand guard. Often they stand too much closer to the burrows so that they can get easily escaped from the prey. While sometimes they give call to the fellow Meerkat about the presence of the prey, but it gives prey the location to the other Meerkat, which can get the other Meerkats into the danger.
Lecture talks about another example about a human who offers his kidney to the another stranger or his relative, according to the passage which is very selfless act. But the lecture says that the man gets some nonmaterialistic reward in return, something in the form of the appreciation, Which cannot be called as an altruistic behavior.
In the conclusion, we can say that sometimes the human or animal behavior can be selfless acts, but in the difficult situations, they think first of themselves.
