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 both are about the behavior concerning altruism, which is sacrificing own interests for another person or animal. The author of the reading states that both humans and animals has altruistic nature which in turn benefits the other but not themselves. The lecturer casts doubts on the claims made in the passage. She claims that even if the humans or an animal sacrifices his own interest, they gain non materialistic rewards.
First of all, the author contends that many living things sacrifice their food and life for the sake of others. The article gives an example of meerkats. In a group of meerkats, few of them acts as guard looking for the predators, while others hunt for the food or eat their food. Those few guarding meerkats risks their life as they are the ones most in danger when the predators arrives, they also sacrifice their food while guarding. The lecturer rebuts this argument. She suggests that when being at guard, these few meerkats eat their food before standing sentinel. Moreover, she elaborates that when a predators comes, these are the first ones to encounter the danger and run away.
Secondly, the author points out an example of an individual donating a body organ to family member or stranger. It is mentioned that the donor does not get reward for doing the donation. This point is challenged by the lecturer. She says that when a donor donates their body part, they are well appreciated by the significant receiver and the society. Furthermore, she argues that these are non materialistic rewards which cannot be gained easily.
In conclusion, the lecturer effectively casts doubts on all the claims and the theories presented in the reading.
