Chapter 3 is the second theoretical unit. This chapter presents the important insight that contemporary human populations and chimpanzee populations in Africa form a whole. In to order to fully understand this, attention is given to the historicity of contemporary chimpanzees and human beings. The chapter addresses the developmental progression over millions of years, since the very emergence of mammals on earth, that brings the populations to the point of their present existence. Martin (1990) presented a phylogenetic overview of primates in his Primate Origins and Evolution. Competencies and aapabilities are discussed here. Members of chimpanzee groups appear to have distinct personalities. Chimpanzee communities are characterized by membersí mutual attachments to one another; these relationships are motivated by both emotional and practical needs. Within these communities, animals communicate intensively and very openly with each other.
