The origin of language, its relationship with human evolution, and its consequences have been subjects of study for centuries.Scholars wishing to study the origins of language draw inferences from evidence such as the fossil record, archaeological evidence, contemporary language diversity, studies of language acquisition, and comparisons between human language and systems of animal ...

[9] [10]: 263 Trombetti estimated that the common ancestor of existing languages had been spoken between 100,000 and 200,000 years ago. [11] In the 1950s, Morris Swadesh was one of the most important supporters of monogenesis. [10]: 215 He created two controversial methods based on previous ideas, namely lexicostatistics and glottochronology.
The origin of language is a hotly contested topic, with some languages tentatively traced back to the Paleolithic. However, archaeological and written records only extend the history of language into ancient times and the Neolithic. The distribution of languages has changed substantially over time.
In 2011, an article in the journal Science proposed an African origin of modern human languages. [10] It was suggested that human language predates the out-of-Africa migrations of 50,000 to 70,000 years ago and that language might have been the essential cultural and cognitive innovation that facilitated human colonization of the globe.

Linguistics is the scientific study of language, [1] involving analysis of language form, language meaning, and language in context. [2]Language use was first systematically documented in Mesopotamia, with extant lexical lists of the 3rd to the 2nd Millennia BCE, offering glossaries on Sumerian cuneiform usage and meaning, and phonetical vocabularies of foreign languages.
In terms of evolutionary theory, historical linguistics (as opposed to research into the origin of language) studies Lamarckian acquired characteristics of languages. This perspective explores how languages adapt and change over time in response to cultural, societal, and environmental factors.
