In the passage, it primarily explains about Altruism and example of it. The passage stated that Altruism is a type of behavior in which an animal sacrifices its own interest for that of another animal or group of animals. There are two different opinion between the lecture and the passage.
First of all, the author points out that 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. On the other hand, the point is challenged by the lecture. The lecture claims that meerkats actually have an advantage of guarding the area.If the danger comes,they are the first ones to escape.
Secondly, the author contends that sentinels guard the others while eating. By standing guard,the sentinel meerkat gains nothing—it goes without food while the others eat. According to the lecture the sentinels eat first before they guard. 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. In contrast, the lecture rebuts this argument. The lecture posits that the other meerkats, which looking for food, are actually greater in danger;also, alarm call might caused other meerkats member together very quickly. those are for tension of predator away from the color.
Finally, the author states that donating kidney is an example of altruism. However, the lecture posits that this in not an act of altruism because people will gain social acceptance and self worth.
