A World without Husbands and Fathers

Last night on the Discovery channel here in Oz: Civilisations focused on a culture almost completely the inverse of many cultural commonalities. The Moso of China do not have an institution of marriage, and no word for "daddy." They are matrilineal and matriarchal. Promiscuity is not only common, but sought after, and jealousy over affection is mocked and discouraged. Men have no role in the upbringing of their children-- indeed, the Moso believe there is no biological link between father and offspring. Instead, uncles take on a father-like role. This unique group debunks the notion that some cultural constructs, like marriage and fatherhood, are not as universal as previously thought. I couldn't find much online about the Moso, but I did find this.
