Primate Behaviour
  1. Social Organisation in Gorillas
    1. Mountain Gorillas live in stable groups of around 10 individuals
      1. Usually consists of one mature dominant male, a number of adult females and their offspring
        1. The dominant male protects the other members of the group, leads them and is the only male that mates with the females.
          1. As younger males reach sexual maturity they leave the group and live alone until they are mature enough to attract females.
          2. Social Behaviour in Gorillas
            1. Grooming is an important activity. One individual picks the parasites from the fur of another reinforcing relationships between individuals
              1. Care of offspring is the role of the mother.
                1. During the first 5 months the infant remains in constant contract with the mother.
                  1. By the age of 12 months, infants will venture as far as 5m away from the mother.
                    1. During this period the female protects the young gorilla as it learns the social and other skills for living independently.
                      1. Further learning takes place at the age of two where the young play together and imitate adult behaviour of foraging for food
                        1. The silverback is important in the development of the young ages 3-6, both in terms of protection from older males within the group and in p0lay as a source of new skills
                  2. Communication System Exists
                    1. A variety of calls, displays and grunts are used to signal danger to other members.
                      1. Facial expressions are also important in terms of recognition.
                    2. Advantages of Social Behaviour
                      1. Females give birth to only one or very few infants at a time to enhance the survival rate of the young.
                        1. The young learn through observation of and play with other members.
                          1. Knowledge and protection of food sources shared in the group
