The discovery of commonality. This remarkable book, which brings together the evolution and archaeology of human social behavior, spans the range from the social groups of the Stone Age to modern digital networks, showing that we live today in social worlds that have developed deeply in our evolutionary past. You will not read a more important book this year. It could make us a little wiser in our self-assessment. A wonderful compendium of history, theories, and fascinating experiments that will captivate you throughout. Written in a style that admirably avoids scientific jargon and sociological terminology, requiring no more than an average human brain to read and understand... a very valuable summary of our existence.
