Are they real?
Any time you get more than a few people living together, you’ve got a society. For many of us, that may mean the familiar milieu of family units, local municipalities and national governments.But there are many ways to organize a group, as the following societies show. Because of circumstance, tradition or other factors, some of these groups have self-organized in ways that might seem alien to those in the mainstream — cannibalism, underground mansions and wild tree-house dwellings are just some of the more notable features of these societies. Others have formed strikingly familiar community arrangements in extraordinary circumstances.
