Chimpanzees and humans are placed together because of their remarkable anatomical and biochemical similarities and the fact that it is thought that they are the most closely related evolutionarily. Indeed, chimpanzees and humans share over 98 percent genetic similarity.
However, humans define themselves not only in terms of physical structure, but also in terms of culture, psychology, intelligence, behavior, religion, and other aspects. In such ways, there is a striking gap between humans and chimpanzees. Humans, for example, utilize complex language with symbols, syntax, and grammar. Humans have complex social structures, such as different types of governments, economic systems, and religious and educational institutions. Humans have complex technologies, such as radios, televisions, computers, communication satellites, and so forth. Humans even study other animals through science and have created unique varieties of plants and species of animals. Even physical, the differences are extensive, as chimpanzees rarely have heart attacks, are resistant to malaria caused by Plasmodium falciparum, and do not go through menopause (Wood 2006). Many religions, as well as Unification Thought, see humans as unique because they are endowed with an internal spiritual aspect or soul.
