“This edited volume of invited chapters honours the four decades of fundamental research by archaeologist Glenn Summerhayes into the human prehistory of the islands of the western Pacific, especially New Guinea and its offshore islands. This area helped to shape and direct many ancient dispersal events associated with Homo sapiens, initially from Africa more than 50,000 years ago, through the lower latitudes of Asia, into Australia, New Guinea, the Bismarck Archipelago, and possibly the Solomon Islands.
