The presence of communication and culture, however varied, is also a human universal. When people gather together in a society, they find ways to convey their thoughts and intentions with verbal and nonverbal symbols. With the development of a characteristic community, cultures develop with distinct language, art, religion, and social systems. These social systems often include hierarchies, by which people organize and rank the individuals or groups in their societies. These are basic universals, and can be found in nearly every human culture in the world.
Differences arise between humans in areas such as culture and specific environmental adaptations.
Nonverbal forms of communication also serve to distinguish one culture from another. For example, in Western societies, a smile indicates happiness or friendship, but in Asia it may be interpreted as a sign of mischievousness. Greetings differ, such as a bow versus a handshake, and it is important to be sensitive to such cultural differences in order to avoid offending someone with a different cultural background. Different beliefs, religions, rituals, values, and ways of life create drastic differences between people across the world. Kung of Africa.
