Scientists doubt that such a thing as "human kindness" in general there

Perhaps there is no such thing as human kindness: the researchers found that the main motivation of sharing resources for humans and primates is to obtain benefits. Analysis of the behavior of 32 people and monkeys has shown that in most cases when they shared their food, they expect to receive something in return.

However, people usually relied on natural interchange of food, while primates were more likely to "trade" products. Dr. Adrian Jaeggi, an anthropologist at the University of California, Santa Barbara, said that the male-dominant among monkeys can produce more food and to exchange it for such non-food services, such as support or pairing.

As for the people, the access to food in varying degrees, all provided, and there is a significant risk of food shortages, even for the "dominant", which leads to the need for equal exchange.

Ultimately, such behavior leads to the interaction between individuals and with the right approach, in any case benefits.
