The Proto-Human language (also Proto-Sapiens, Proto-World) is the hypothetical most recent common ancestor of all the world's languages.
The concept of "Proto-Human" presupposes monogenesis of all recorded spoken human languages. It does not presuppose monogenesis of these languages with unrecorded languages, such as those of the Paleolithic or hypothetical Neanderthal languages. Advocates of linguistic polygenesis do not accept the notion of a fully developed Proto-Human language and consider the world's language families independent developments of a proto-linguistic form of communication used by archaic Homo sapiens.
If the assumption of a "Proto-Human" language is accepted, its date may be set anywhere between 200,000 years ago (the age of Homo sapiens) and 50,000 years ago (the age of behavioral modernity).

Famous quotes containing the word language:
“The “sayings” of a community, its proverbs, are its characteristic comment upon life; they imply its history, suggest its attitude toward the world and its way of accepting life. Such an idiom makes the finest language any writer can have; and he can never get it with a notebook. He himself must be able to think and feel in that speech—it is a gift from heart to heart.”
—Willa Cather (1873–1947)
