The old world monkeys have a duplicated opsin gene that is lacking from other primates. The gene gives them the ability of having a better vision of orange and red areas of the light spectrum. The ability helps them choose nutritional food substances to consume (Zimmer, 381). As the world develops, the climate changed and the fruits became scarce and the primates had to change their strategy towards smell for survival purposes. The change of strategy from the sense of smell to the sense of sight changes the social skills of primates. The primates have to rely on their sense of smell to choose food and in some circumstances communicate to each other. There was development on the language of odors in the primates.

It will use the molecules to recognize her lamb bond with it until it is ready to be on its own. The transition enabled primates to respond more emotionally to the sight of other primates (Zimmer, 382). The transition results in change of the muscles in the face-helped primates make expressions. The expressions in the face of the primates were a development of the brain. They had the ability to know of understanding what other primates were doing.

Robin Dunbar, a specialist in the area, believes that the size of the human brain continued to develop ever since (Zimmer, 383). Numerous tests tested the social and mental skills of small chimpanzees and those of adult chimpanzees. The results of the research indicate that the children learn faster when they observe what their adult counterparts do. Children develop their social skills by observing what the activities of
