Natural History of Britain

Episode Four

Prehistoric Britain is the period between the arrival of the first humans in Great Britain and the start of recorded British history. The period prior to occupation by the genus Homo is part of the Geology of the British Isles. The history of Britain is conventionally reckoned to begin in AD 43 with the Roman invasion of Britain, though some historical information is available from before this. Prehistory is commonly divided chronologically into distinct periods, based on the development of tools from stone to bronze and iron as well as changes in culture and climate, but their boundaries are uncertain, and the changes between them gradual; the dates of the changes are generally different from those of continental Europe.
