The lecture gives us an example of reexamination of earlier beliefs and assumptions on the topic of altruism. The lecture refutes the passage about some behaviors that were considered as altruism. Contrary to the passage that sentinels guard the group in exchange for nothing, the lecturer demonstrates that those sentinels eat before they service the rest of the group with a full stomach. Furthermore, the lecturer remind us that different from the traditional view that the sentinels are the most vulnerable to the predators as they are exposed to them, the new findings prove that the guarders even have the priority to survive since they are the first to notice the danger of the intruders thus can be prepared to escape into the nearby burrows at the first time. And the alarm that was once deemed as the altruistic signal to remind the group members of the advent danger, is now inclined to be explained as a sneaky method to transfer the attention of the predator to the rest of the group in order to gain a better chance for self survival. As to human beings, the lecturer indicates that the behaviors that are commonly perceived as altruistic ones are actually motivated by underlying self-interest. For those who share food or even donate organs to relatives or strangers, appreciation and approval from the receiver and especially the society can be more valuable rewarding than a simply materialistic one.
