Origin of Human Language in an Evolutionary Context: Evolution-Progression Model

This article approaches what is considered to be a linguistic enigma with an interdisciplinary scientific approach. In this manuscript, the author analyzes the infant developmental stage, hu-man anatomy, animal behavior studies, and anthropological changes. Furthermore, prominent theories in the field, such as the provisioning model, ADHD (attention deficit hyperactivity dis-order) theory, and the metabolic hypothesis for human altriciality are considered in an evolutio-nary context to unravel the origin of language. First, two evolutionary adaptations in humans, bi-pedalism and delicate muscle movements, resulted in the lack of a need for “hyperfocus”. Second, a relatively safe and rich environment replaced “hyperfocus ” with social cohesion. Third, a bur-geoning social interaction ushered in natural selection, whereby child helplessness or early par-turition supported exceptional self-consciousness (intelligence). The result of concentrated self-consciousness, which involved enlargement of the posterior parietal cortex (sense of self), pre-frontal cortex (social cognition), and temporal lobe (language interpretation), was human lan-guage. Language was not a sudden revelation; instead, it was a gradual process and a built-in part of the evolutionary sequence. Last, this article implies how language might have begun in accor
