Again, I'm not an anthropologist, but it seems to me that every society has rules and regulations that often are geared primarily to making sure that any children born have a place in the society, are socially legitimate.
Encore une fois, je ne suis pas anthropologue, mais il me semble que toute société a des règles qui, souvent, visent principalement à assurer que les enfants qui naissent ont une place dans la société, possèdent la légitimité sociale.
