“Culture is an emergent property of human groups, a new property of the whole not manifested in the parts themselves. And it arises from humans having the brains and social systems that allow for retaining and exchanging ideas.
Human culture also accumulates. This means that brains and social systems capable of coping with more and more stuff are increasingly advantaged across time. And it also means that the force that culture has been applying to our evolution has been increasing over the past ten thousand to forty thousand years. Once humans evolved to be capable of teaching and learning, they developed a parallel evolutionary strand, cultural evolution, side by side with genetic. These two strands intersect repeatedly in many places and times. Each leaves its mark on the other. ” —Nicholas Christakis, Blueprint: The Evolutionary Origins of a Good Society
Christakis’s ‘social suite’ is a range of traits that are common among all human societies, though not always manifested in the same way. For more information, read Howard Rheingold’s review of Blueprint. When it comes to the age-old question of Nurture versus Nature, Christakis answers that it is both, like a double helix. This is not a unique perspective.
