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

The lecture completely refutes the passage. It is said in the lecture that, the perceived acts of altruism are nothing more than sneaky methods of gaining advantage for one’s self.Contrary to the belief in the passage that sentinels risk their lives for the cause of the whole group, the professor says that the meerkat sentinels are in fact less prone
to outside threats. The alarm sentinels give off causes to group to move rashly which draws the predators attention towards them, thus drawing away the attention from
the sentinels. The lecture refutes the fact that these meerkats are altruistic in the sense that they gain nothing in exchange of their services. In fact, researches have shown that they have a full stomach as they perform this “altruistic” duty and have a better chance of escaping from danger because they witness it ifrst Proffesor also offers a different underlying motivation that causes people to believe that acts such as donating an organ or sharing food with someone in need are altruistic. She says that people gain appreciation as a result of such acts, which may be deemed by some much more important than materialistic gains.
