Subtitled `a critical review of some archaeological and craniological concepts',this is an innovative and controversial study of the Beaker Culture problem; diffusion or migration into Britain. The first part of the book critically reviews previous work on the problem and suggests that the processualist revolt against migrational explanations might have been an error in this case. The second part presents an original study of English Neolithic and Bronze Age crania which, although inconclusive, moves a step nearer to a migrationist explanatory framework.
