During much of the Palaeolithic, the British Isles indeed formed 'the edge of the world' (Lang and Keen, 2005), which makes this northwestern tip of the Eurasian landmass a good laboratory for monitoring the ebb and flow of human occupation and hence hominin adaptations-indeed, this was an important rationale behind the Ancient Human Occupation of Britain (AHOB) project.
