Humans are the only organisms known to be able to communicate by means of abstract symbols and speech. Ever since the inception of the Darwinian theory of evolution tracing the decent of man from its primeval ancestors has been a generally accepted nuance, however the origin and development of speech has been much more bewildering. Language has grown to be such an identifying aspect of man that it has often been accepted that speech is a trait bestowed upon is by a greater being. However this essay will focus on scientific theory and the purported origins, mechanisms, reasons for, development of civilization and future evolutionary aspects in relation to human speech. The course of the formation of human phonetic language and communication was one that relied on natural selection as well as selective pressures which led humankind to adapt in such a way to communicate with one another to form the basis for civilization.

The mechanisms for speech are the properties which should first be interpreted in order for one to develop an understanding of the aspects of human speech and its implications. There are three main processes involved with the action of sharing an idea between members of the human species. They are the articulation and synthesis of an idea in the motor cortex, the resulting motion and action that occurs within the lungs, glottis, velum, tongue, lips and jaw to express the idea and the sound generation model which ones brain has been accustomed to operate the larynx in such a way as to produce understandable language. When an idea is first synthesized in the motor cortex, the brain begins by sending signals to the parts of the body such as the lungs and the larynx to initialize the

vocalization the thought. The lungs then expel air to pass over the vocal cords located in the larynx that orient themselves in such a way as to express the idea by way of sound out of the buccal cavity. Though a complex procedure from a scientific standpoint, the process takes such little time and effort that one usually does not realize the complexity of the mechanisms behind their expression of ideas through spoken communication. These mechanisms may also be aided in communication between people, with gestures or body language which may be unique to certain cultures and distinct groups. For example, people of Italian backgrounds are very well known to express emotion as well as language with the aid of gestures and physical movements. The formation of an idea and its expression in the form of vocalization, with many different languages and near infinite ideas that can be seen is a trait that is unique to mankind.

Humankind's evolution from communication systems in nonhuman primates such as Australopithecus afarensis to the speech that exists today is a process which has puzzled scientists and philosophers. If the basic structural principles of language cannot be learned from bottom up. This is evident as we as a species are light years ahead in terms of development in the area of linguistics as compared to other primates which have been existent alongside us for millenia. Thus, it must be inferred that our species underwent a mutation within our genes that allowed us to develop speech with a magnitude and effect on our species equivalent to that of the Big Bang. This scientific theory is supported by humankind creation and fostering of the idea of civilization, as it is speech and communication that is the conduit for successful living in a society of intellectual, cultural and material development. In addition, the conceptualization of speech among those of the human species can be seen as an action of natural selection. Those that did not have the capacity to communicate were not Maglalang 3
