Political conservatism is associated with prioritizing friends and family. Political liberalism, on the other hand, is more associated with drawing a bigger circle around yourself. This kind of where we draw the line as individuals in our societies is is can be, i think, the source of some of the most profound political disagreements that we have in our current societies. It also pertains to questions about nationalism and social welfare - you know, all things that kind of wear these fault lines on those things to some extent. I'm not going to say that one thing is better than the other when it comes to understanding people's different scopes of moral regard," he says.
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.
