Mankind is descended directly from Bonobos. It is a matriarchal society in which females join other troops (word for group of apes) by beginning a relationship with the dominant female. Sons of the dominant female lead the males. Sex is used for social purposes including bonding and settling disputes. Marriage means a loving relationship, but not an exclusive one. Bisexuality and pansexuality are the norm, but homosexuality and heterosexuality are frowned upon and considered prudish.
