Dispersals and diversification offers linguistic and archaeological perspectives on the disintegration of Proto-Indo-European, the ancestor of the Indo-European language family. Two chapters discuss the early phases of the disintegration of Proto-Indo-European from an archaeological perspective, integrating and interpreting the new evidence from ancient DNA. Six chapters analyse the intricate relationship between the Anatolian branch of Indo-European, probably the first one to separate, and the remaining branches. Three chapters are concerned with the most important unsolved problems of Indo-European subgrouping, namely the status of the postulated Italo-Celtic and Graeco-Armenian subgroups. Two chapters discuss methodological problems with linguistic subgrouping and with the attempt to correlate linguistics and archaeology. Contributors are David W. Anthony, Rasmus Bjorn, Jose L.
