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 lecture are about altruism, a behaviour in which animals sacrifice their own self-interest for other animal beings. The reading argues that altruism is an unselfish act in which animals would sacrifice themselves for the benefit of others. The lecturer, however, disagrees with the reading, stating that while altruism may be an unselfish act, it can also backfire. The reading states that humans would donate body organs to their family members and strangers. This benefits the receiving group, but offer little reward to the donors. The reading also states that sentinel meerkat would also sacrifice its own interest to keep on the lookout for predators to protect and alert the other meerkats that are hunting or eating food.
The lecturer disagrees with the reading, claiming that in the case of humans, the donors would donate organs to family members or strangers just to gain a sense of appreciation and self-worth from it. Which is contradicting to what the reading claim. She also states that researchers have found out that sentinel meerkats typically eat before standing guard, and that if a predator were to come in, the sentinel meerkats would sound off the alarm cry and be the first ones to escape into its burrow. While the other meerkats are at greater risk of being hunted by the predator as the alarm cry can cause them to act rashly and run into the predator without realizing.
