However, in the lecture, professor makes a series of points that cast doubt on all the arguments presented in the passage. She states closer view by recent experiment showed different explanation for each of the examples provided in the reading.
First of all, professor clarifies that Meerkat sentinels in contrast to the idea presented in the reading do not sacrify their food for other group memeber. In other word, they eat before standing as sentinel and their stomach is full.
Also, lecturer refutes the idea of the reading about the altruism act of Meerkat sentinel. She states they stand near the burrow and they escape immidiately after seeing predetor. In fact, sending alarms might cause distraction and draw predetor's attention from the caller to the group.
Lastly, the professor points out that donating kidney to relative or strangers which the reading called it selflessness act could be explain differently.
