This book is Volume 13 in the Sydney Symposium of Social Psychology series. Theaim of the Sydney Symposia of Social Psychology is to provide new, integrative insights into key areas of contemporary research. Held every year at the University of New South Wales, Sydney, each symposium deals with an important integrative theme in social psychology, and the invited participants are leading researchers in the field from around the world. Each contribution is extensively discussed during the symposium and is subsequently thoroughly revised into book chapters that are published in the volumes in this series.

The “Nostratic” hypothesis — positing a common linguistic ancestor for a wide range of language families including Indo-European, Uralic, and Afro-Asiatic — has produced one of the most enduring and often intense controversies in linguistics. Overwhelmingly, though, both supporters of the hypothesis and those who reject it have not dealt directly with one another’s arguments. This volume brings together selected representatives of both sides, as well as a number of agnostic historical linguists, with the aim of examining the evidence for this particular hypothesis in the context of distant genetic relationships generally. The volume contains discussion of variants of the Nostratic hypothesis (A. Bomhard; J. Greenberg; A. Manaster-Ramer, K. Baertsch, K. Adams, & P. Michalove), the mathematics of chance in determining the relationships posited for Nostratic (R. Oswalt; D. Ringe), and the evidence from particular branches posited in Nostratic (L. Campbell; C. Hodge; A. Vovin), with responses and additional discussion by E. Hamp, B. Vine, W. Baxter and B. Comrie.
