The Evolution of the WordThe purpose of this essay is to identify evolutionary evidence for the word. The articles reviewed in this article state the evidence for the evolution of language. Much is not known about the evolution of language, however, fossil evidence points to adaptations to language appearing between 1.5 million and 500,000 years ago. Fossil evidence of the evolution of language is shown in early hominids up to one of our well-known ancestors, homo erectus. There are differences between the bone structure and hard tissues of modern humans compared to those of chimpanzees and bonobos (Boer, 2005). Speech is a unique feature that so far only humans have developed. This feature was most likely a prerequisite for the development of culture within human society. Across society, it has been shown that speech can range from extremely complex to surprisingly simple. Finally, how children acquire language has become better known, helping to provide the starting point for the evolution of language. The physical aspect of language has become an interesting topic of discussion over time because it is difficult to follow its evolution. Language adaptations such as the vocal tract and breathing control have left traces in the fossil record that continue to be studied to this day. Acoustics and speech perception skills are a crucial step in recognizing vocal tract resonances, or formants in human speech. Tract resonances work like a band-pass filter, taking any sound emanating into the larynx and shaping it into peaks and valleys (Fitch, 2000). Although all mammals have similar sound production, only humans make heavy use of formants. The study of this has been investigated even by the youngest of inf...... half of the article ......
