Communication between individuals of the same species is one of the most crucial segments of any species’ existence. Communication can occur both verbally and nonverbally and, according to Birdwhistell (1970, as cited in Moore et al. 2014, p. 4)) and Philpott (1983, as cited in Moore et al. 2014, p. 4), 60 to 70% of human communication is nonverbal. Nonverbal communication in humans consists of several subcodes, like haptics, kinesics, proxemics, physical appearance, vocalics, and chronemics. They serve to repeat, conflict, complement, substitute and accent what is being said verbally. Humans are the only animals who use their brains to communicate verbally, i.e. use language for communication together with nonverbal cues. Instead of subcodes, animals use signals. The most common types of signals, according to Håkansson and Westander (2013) are chemical signals, known as pheromones. There are also acoustic, olfactory, visual, tactile, seismic (felt through vibrations), and electrical signals that animals can use. Animals communicate to obtain their identity, to recognize others, to protect their territory, find shelter and food, mate, and raise their young in order to obtain their species. The works that tried to find and explain connections between animals and humans with regard to nonverbal communication started a long time ago (Moore et al., 2014), and it is believed that nonverbal communication is a mixture of innate and learned behaviour. This paper deals with nonverbal communication in humans and animals and its different subocdes, as well as its use in humans and different animal species. It also discusses the difference between innate or learned behaviour in humans and animals and its connection to nonverbal communication.
