Alruism - Selfnessless or selfishness?

The passage talks about the act of altruism, which is described by selflessness expressed by animals to keep other members safe and sound. Altruistic animals are ready to risk themselves for no personal gain. However, the professor argues that no animal is self-centered. There is a possibility that they try to keep themselves at a situation where they can escape easily. There have been extensive studies about Meerkats, the mammals which are found in burrows. The passage portrays the unselfish nature of the species. When they move in a group to hunt for food, a sentinel or guard places themselves at a place where they keep an eye on predators and alarm the other members in case of emergency. There are cases when the guard is not fed and have to walk away alone keeping its life at stake. This way, it plays an important role for survival of other members. However, the professor had contrast opinions. She keeps forward multiple reasons that question the altruism exhibited by the species. She mentions how the sentinels are closest ones to burrows, making their escape from predators easiest. In such a way, the others are left in danger. She also talks about how alarms and cries may act as bane for the animals. Collecting together at a place and forming a group may make it simpler for the predator to hunt. A point was also raised by her that sentinels fill their stomachs first before guarding others. In other way, they do not sacrifice their food or lives. Another example is that of humans who display altruism by multiple ways such as donating their organs to relatives, or even strangers. Yet, the professor says it’s also important to take count of unmaterialistic things such as increased self-worth, appreciation and acceptance in society.
