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.
Summarize the points made in the lecture, being sure to specifically explain how they cast doubt on points made in the reading passage.
The lecture contradicts the passage by explaining self-benefits obtained by sentinel of Meerkats and altruist human. The passage describes the trait of selflessness in humans and animals by giving example acts. However the lecture refutes these descriptions by pointing out the benefits that are obtained out of these acts by animals and humans who do them.
First, the lecture states that the sentinel of Meerkats eats before the group sets for searching for food. So, it actually doesn’t lose its appetite. However the passage says that it cannot get its food because it serves as guard while rest of the group searches for its food. So, from the new findings stated in lecture it can be understood that the sentinel is not really selfless to sacrifice its food for the sake of the group.
Second, the lecture claims that the sentinel is more likely to escape from predator than rest of the group. This is because as the sentinel of Meerkats gives alarm cry, the rest of the group is becomes frightened and they try to escape faster. Due to these sudden movements the predators changes its attention from sentinel to rest of the group. Since the sentinel is nearer to its home and as it notices the predator first while rest of the group is busy in gathering its food, it can escape easily. So, the sentinel is actually benefitted here. Such a claim opposes the argument made in passage, the passage says that since group has stronger defending mechanisms by acting together, the lone sentinel is more probable to be attacked by the predator.
Third, the lecture explains that due to selfless acts humans get appreciation from the society and hence they would be happier. Anyways these non-material benefits are completely ignored by the passage. The lecture opposes the passage by illustrating that by helping others humans actually don’t act completely selflessly.
