The "Early Palaeolithic" covers the periods conventionally labelled as ‘Lower’ and ‘Middle’ Palaeolithic. Exploring our Past (1991), identified three main themes for national Palaeolithic research: physical evolution; cultural development; and global colonisation. These national themes have subsequently been kept under review and periodically updated (English Heritage/Prehistoric Society 1999 and 2008). Alongside the broad national framework, it has become increasingly apparent that the diversity of the Palaeolithic resource at the regional level merits the development of regionally-focused frameworks for Palaeolithic research, identifying
