What is the relationship between stones and the color of human eyes? In this episode of Johan Norberg’s New and Improved, Norberg explains the fascinating evolutionary origins of human collaboration.

Our survival is rooted in our ability to communicate and collaborate, so much so that it seems built into our very biology. Unlike other species, we have evolved qualities that broadcast rather than conceal our attention.

And as humans evolved, so did how we work together. From surviving in the wild to reaching out into space, we constantly organize ourselves to benefit from the knowledge and abilities of others.
