Linguistic monogenesis and polygenesis

Hypotheses on the origin of languages

In historical or evolutionary linguistics, monogenesis and polygenesis are two different hypotheses about the phylogenetic origin of human languages. According to monogenesis, human language arose only once in a single community, and all current languages come from the first original tongue. On the other hand, according to the polygenesis, human languages came into being in several communities independently, and current tongues derived from different sources.
