The Human Swarm by Mark MoffettIn most accounts of world or macro history, you get a few introductory sections or chapters on our hunter-gather past before moving on to the civilizations of written history. Yet 6,000 years of written history represents only three percent of our collective 200,000 year history as a species. Surely this span of time has more relevance and deserves more attention than it is typically given.

The Human Swarm by biologist Mark Moffett does not suffer from this limitation; it takes 21 chapters and 275 pages before the author gets to the societies of written history. In what truly represents a biologist’s take on the history of our species and societies, the majority of the book discusses our deep evolutionary past and our connections to other social species, including chimpanzees, bonobos, dolphins, elephants, and even ants.

Blueprint by Nicholas ChristakisSocial scientists can approach the study of human culture, broadly, by either focusing on differences or similarities. All too often, they choose to accentuate the differences, elaborating on what divides us and on our more aggressive and sinister behaviors. Since cultural differences are so obvious, the countless cross-cultural variations in human behavior would seem to dispel the possibility of cultural universals.

In Blueprint, Nicholas Christakis makes the opposite case: that our genes code for universal traits—the social suite—that underlie all superficial variation in human behavior and provide the foundation by which we form social networks. Christakis uses the metaphor of viewing two mountains from a 10,000 foot plateau, noting that one mountain appears three times the size of the other, until you descend from the plateau. Then, you realize the two mountains are 10,300 and 10,900 feet tall, and are not so dissimilar from this enlarged perspective.
