Not So Distant Relatives: Evolution of Human Vocal Production

Humans and non-human beings are closely related to each other in physical form, but they make each other different. Some people think that there is no big difference between humans and nonhuman primates, but the most obvious difference is the way they communicate. Communication other than human beings is much simpler than human beings. Both have ways of communicating with members, but their voice communication system is how they produce their voices and how they organize them. No, it includes their society, and what they intentionally use.

Evolutionary musicology is a subfield of biology linguistics, theoretically based on psychological mechanisms of music perception and production in evolution theory. It encompasses voice communication by nonhuman animal species, the theory of human music evolution, and the universality of intercultural humanity in musical ability and processing. "When dealing with sexual options, primitive people, or more precisely, human early ancestors, can use his voice to create real music rhythms, that is, like a part of the current Gibbon It will be seen to sing to singing, to express emotions such as love, jealousy, victory, to challenge, to mimic music with a clear voice - this power is particularly useful during gender search You can draw a conclusion from a known analogy.The scream can create words that express various complicated emotions.

The emergence of throat decline is an important innovation in the evolution of speech, but this sound production mechanism involves cost. This causes and alerts human-made swallowing disorder (such as dysphagia), but the well-known Heimlik motility asphyxia is the fourth leading cause of accidental death in the United States (USA Injury report) . It is expensive to have a throat at the top of the trachea, so there are already forms of voice and vocalization before our various human vocal folds evolve (Lieberman, P., 2007). Furthermore, with the risk associated with the development of such a pathway, evolution is motivated to advance its own advantages and is most likely to increase the benefits of voice function. That is, the benefits of throat drop (voice communication system) make biological risk worthwhile.
