We're very suspicious of acts of altruism that we think are tainted by self interest. We do try to figure out, what is the reason? Why are you doing that? What are your motives? And are your motives pure, or are your motives calculating? It doesn't take a big leap of logic to start to question when someone is doing something nice for some one else. Er wisdom came from an anthropologist called richard lee who working with a bushman in the calahari for his research. He'd developed this reputation in the community in which he worked as being quite stingy because he wanted to study how they ate their natural subsistence strategies.
Cooperation is the means by which life arose in the first place. It’s how we progressed through scale and complexity, from free-floating strands of genetic material, to nation states. But given what we know about the mechanisms of evolution, cooperation is also something of a puzzle. How does cooperation begin? A biologist by training, Nichola Raihani looks at where and how collaborative behavior emerges throughout the animal kingdom, and what problems it solves. She reveals that the species that exhibit cooperative behavior — teaching, helping, grooming, and self-sacrifice — most similar to our own tend not to be other apes; they are birds, insects, and fish, occupying far more distant branches of the evolutionary tree. By understanding the problems they face, and how they cooperate to solve them, we can glimpse how human cooperation first evolved. And we can also understand what it is about the way we cooperate that has made humans so distinctive and so successful.
