Bonobos (the good guys):
* They live in an area with a relatively large supply of available food. * They travel in much larger groups because food is abundant. * There is a reduced level of violence between males, between males and females, and between neighboring groups. * There is no evidence of rape, infanticide, or battering of females. * The top female and male are equal to each other. * Females cooperate much closer with other females, forming coalitions for protection and mutual support. * Males never cooperate with each other for defense or to attack females. Even the highest ranking male can be defeated by females ganging up on him. * Females engage in mutual friendships that include erotic love-making, mutual masturbation, lesbianism (genito-genital rubbing) and grooming as a way of bonding. * Males also practice mutual masturbation, and there is no competition for mating with females capable of hiding when they can become pregnant. * Bonobos have sex to make friends, and can mate or have sex dozens of times a day.
Chimpanzees (the bad guys):
* They live in smaller groups because food is scarce -- mostly fruit and meat. * Neighboring groups of chimps engage in warfare -- one group will form raiding parties to find isolated males of another group and beat them to death -- with a great deal of revelry and enthusiasm. * Young males when they mature will systematically beat and harass females until all the females are submissive to them. * Females prefer mating with the more violent, aggressive males because they will afford them more protection from other males, even though the females will often times be abused. * The females also have established hierarchies, and their children are born into the status positions of the mother (to be lost or improved by the individual later). · Sex is traded for food, favors, and status seeking. * Males will form alliances to gain and keep a high rank, with far more frequent violence. * Hunting is a regular feature, with a great deal of blood lust shown at the time of the kill (similar to genocidal attacks).
