In this lecture, the speaker completely refutes the reading passage and cites several latest findings of meerkat, which explain their eating habits in a quite different way from the previous researches. First, contrary to the pathetic image given in the reading passage as a sentinel without food, the speaker says that it often stands guard after eating, that is, it guards for the others with a full stomach. Second, meerkats usually hunt near a barrel and the sentinel has the biggest chance to hide himself immediately from the predator. But the former findings as described in the passage indicate that they have the least chance to run and seek shelters. What’s more, when the other meerkats hear the alarm, they either gather together or scatter, which draws the attention of the predators. In comparison, the sentinel has its own chance to seek safety. At last, as for human beings, the speaker opposes to the notion given in the reading passage that altruistic people gain nothing for themselves with an example of kidney donors. They obtain the appreciations and approval from the society and a sense of self-worth. Therefore, what people get from altruistic action should also include nonmaterial returns.
