Image of an Amazon women and a child from a tribe located in the Western Amazon Rain Forest.  Typically, Amazonian tribes are much more tolerant of young children and do not reprimand them as is common in western cultures.  Moreover, some Amazon tribes believe if a woman has relations with more than one man, then all the men are fathers of the child.  Recent studies by anthropologists of remote South American tribes have questioned the conventional belief that a nuclear family with two parents is the preferred arrangement for raising children.  Anthropologists call this phenomenon "partible paternity."  Although this concept many be strange to westerners who were brought up with the tradition of one biological father per child, many Amazon tribes actually believe that a child can have multiple fathers.
