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 withou 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 togethe to fend off a predator. So the altruistic sentinel behavior helps ensure the survival of other members of the meerkat's group.
The article states that altruism is an act of selflessness and provides two reasons of support. However, the professor opposes the articles and refutes each of the reasons by stating points from the recent study.
Firstly, the reading claims that many animals and people share food and donate organs to others even though it doesn't benefit them. The professor refutes this point by saying that sharing food with others and donating organs to people in need brings appreciation to the donor from the society. She says that for some people non materialistic rewards are very valuable and they therefore tend to work for others in need.Hence, the professor infers that there is no act of selflessness by doing so.
Secondly, the reading gives an example of an animal called Meerkat, which acts as an sentinel, standing guard and looking for predators while the others hunt for food or eat food they have obtained. It states that when meerkat warns the others when it locates a predator, thereby risking its life and also sacrificing its food to guard. But the professor opposes this by stating that the extensive research on meerkat has revealed that, the meerkat acing as a sentinel, eats before standing guard and looking for its predators. Also, it is the easiest for the sentinel to escape after warning about the predator as the sentinal often guard near the burrows. So, they can hide themselves in the burrows soon after warning about the danger.
The reading also tells us that the sentinel has to flee alone, which might make it more at risk to a predator, than the other animals in groups. The professor contradicts this by stating that when the sentinel warns other animals, the other animals in groups try to escape together hence draws attention towards them and away from the sentinel.
