| Summary: | For one and a half century, linguists have ben avoiding questionning the genetic and evolutionary processes of human language and prefer to continue reconstructing previous stages of present languages using the method of comparative-historical grammar elaborated in the 19th century. But since ca. 1990 some resarchers from various disciplines have taken over this issue by intertwining the conceptual and instrumental tools of their respective disciplines. After reminding that the origin of natural languages, of grammar and of human language are three separate questions (part I), this contribution enumerates the disciplines jointly interested in language evolution while evoking the appeal of language for evolutionary biologists (part II). It also yields material about the contribution of evolutionary neurosciences to the study of language genesis (part III).
