Animals Seem to Demonstrate Altruism

Animals Seem to Demonstrate Altruism

Are animals willing to sacrifice their well-being to benefit another animal? Altruism is a human characteristic thought to be missing in animals. As scientists study animal behavior more deeply, they see many cases where animals seem to demonstrate altruism. Those include jumping into a fight to save another animal when there is no direct benefit to the intervening animal. In one case, killer whales were hunting a sea lion. Suddenly two humpback whales charged in and pushed the killer whales away, allowing the sea lion to escape. People observed that happening three times in the same area.

There are also situations where animals seem to demonstrate altruism by giving food away. Vampire bats need a constant supply of blood because they can’t survive more than 70 hours without it. Researchers have seen vampire bats regurgitate blood when an individual misses a meal. In one case, a vampire bat gave away so much blood that it starved to death. Studies of meerkats, a species of mongoose in southern Africa, have shown that one couple will breed the offspring and other adults raise the babies. Studies of bonobo primates have demonstrated that they share food both in captivity and in the wild.

Are those the behaviors we thought that only humans exhibited? One constant danger in studying animals is our tendency to anthropomorphize animal behavior. In other words, we interpret animal behavior in light of human behavior rather than looking at the possible reasons for the animal’s actions. You can see this by looking at how people treat and talk to their dogs. The reality is that the dog has learned where it gets its food, its sensual pleasure, and its security. No matter how much support the dog receives, it will still chase the cat, eat the feces of another dog, and bark at a time that displeases the owner. Dog owners tend to overlook those animal instincts and behaviors, and they may even put clothing on the dog.

Researchers can see that all animal behavior in the wild has some kind of survival benefit. In the cases above, the whales don’t have sympathy for the seal. Killer whales attack humpback whale babies, and the best defense the humpbacks have is to drive the killer whales out of the area. Vampire bats are not successful in getting blood every time they go out, so sharing benefits all of the bats because the next night might be their time to be unsuccessful. A similar scenario is present with monkeys sharing.

These animals seem to demonstrate altruism but still resort to survival behavior when under stress.
Chimps raised in human homes do not become humans. When a human invades their territory, they resort to violent behavior. At the same time, pure altruism is a trait available to humans, but not all humans demonstrate it at all times. There is a saying that humans can act like animals, but animals cannot act like humans. The death of Christ on the cross is the classic example of sacrificing one’s self to benefit even those who reject you.
