Funny Monkeys/Chimps 4

Behaviors

Anatomical differences between the Common Chimpanzee and the Bonobo are slight, but in sexual and social behaviour there are marked differences. The Common Chimpanzee has an omnivorous diet, a troop hunting culture based on beta males led by an alpha male, and highly complex social relationships. The Bonobo, on the other hand, has a mostly frugivorous diet and an egalitarian, nonviolent, matriarchal, sexually receptive behaviour. Bonobos are well known to have frequent sex, with bisexuality the norm for both males and females, and also to use sex to help prevent and resolve conflicts. Different groups of chimpanzees also have different cultural behaviour with preferences for types of tools. The Common Chimpanzee tends to display higher levels of aggression than the Bonobo.

Oh my God! There are many louses on your hair.

Social Structure

Chimpanzees live in large multi-male and multi-female social groups called communities. Within a community there is a definite social hierarchy which is dictated by the position of an individual and the influence the individual has on others. Chimpanzees live in a leaner hierarchy in which more than one individual may be dominant enough to dominate other members of lower rank. Typically there is a dominant male referred to as the Alpha male. The Alpha male is the highest-ranking male who controls the group and maintains order during any disputes. In chimpanzee society the 'dominant male' does not always have to be the largest or strongest male but rather the most manipulative and political male who can influence the goings on within a group. Male chimpanzees typically attain dominance through cultivating allies who will provide support for that individual in case of future ambitions for power. The alpha male regularly displays by making his normally slim coat puffed up to increase view size and charge to look as threatening and as powerful as possible. This serves to to intimidate other members in an attempt to hold on to power and maintain authority, and it may be fundamental to the alpha male's holding on to his status. Lower-ranking chimpanzees will show respect by making submissive gestures in body language or reaching out their hand while grunting. Female chimpanzees will show deference to the alpha male by presenting their hind-quarters.

Do I look cute with this mouth style?

Female chimpanzees also have a hierarchy which is influenced by the position of a female individual within a group. In some chimpanzee communities, the young females may inherit high status from a high-ranking mother. The females will also form allies to dominate lower-ranking females. In contrast to males who have a main purpose of acquiring dominant status for access to mating privileges and sometimes violent domination of subordinates, females acquire dominant status for access to resources such as food. High-ranking females will often get first access to resources. In general, both genders acquire dominant status to improve social standing within a group.

Keep silent! I bring my nephew with me.

Its often the females who choose the alpha male. For a male chimpanzee to win the alpha status, he must gain acceptance from the females in the community as they are the ones who actually dictate the lifestyle: the females are the ones who ensure the survival of the next generation; they have to make sure that their group is going to places that supply them with enough food. In some cases, a group of dominant females will oust an alpha male who is not to their preference and rather back up the other male who they see potential of leading the group as a successful alpha male.
