Altruism in meerkat and humans

The reading and lecture are both about altruism which is a type of behaviour when people or animal acts in regard of other's benefit, sacrificing its own profit. The author of a reading passage provides two examples that he consider as an altruistic behaviour. However, a lecturer casts doubt on those examples. She provides information with proof that such behaviour in fact bring individual some benefits and those acts can not be considered completely altruistic.
Firstly, the author of reading passage believes that donating body organs is an act of altruism, as donor gains no benefit from it. This point is challenged by the lecturer. She says that donors are gaining appreciacion from society. Such immaterial benefit can be really valuable for some people, so that people might donate organs, expecting reward. Those expectation are casting doubt that their donation is an example of pure altruism.
Secondly, the author of passage claims that a meercat that stands on guard and look for predators gains no benefit from such action and put himself in more danger than other meercats, thus his behaviour is altruistic. On the other hand, the lecturer provides new data about meercats. According to her, new research figured out that in fact the meercat that is looking for predators is in more advantegious situation as he is already got food, he is the first one who see the danger and because of his location, he have more chances to escape than other members of meercats society.
Lecturer effectively challenges the claims in reading passage, providing new data that might disprove the examples of behavious, that was considered altruistic before.
