because the indigenous Mesolithic Britons came to adopt the agricultural practices of continental societies. Either way, it certainly emerged through contact with continental Europe, probably as a result of centuries of interaction between Mesolithic people living in south-east Britain and Linear Pottery culture (LBK) communities in north-eastern France. Between 4500 and 3800 BCE, all of the British Isles came to abandon its former Mesolithic hunter-gatherer lifestyle, to be replaced by the new agricultural subsistence of the Neolithic Age. Throughout most of Britain, there is little evidence of cereal or permanent dwellings from this period, leading archaeologists to believe that the Early Neolithic economy on the island was largely pastoral, relying on herding cattle, with people living a nomadic or semi-nomadic way of life. It is apparent that although a common material culture was shared throughout most of the British Isles in this period, there was great regional variation regarding the nature and distribution of settlement, architectural styles, and the use of natural resources. There is archaeological evidence of violence and warfare in Early Neolithic Britain from such sites as West Kennet Long Barrow and Hambledon Hill, with some groups constructing fortifications to defend themselves from attackers. Contemporary archaeologists have no direct proof of gender relations on the island at this time, although most believe that it was probably a male-dominated society, in keeping with all recorded societies that practice large-scale animal husbandry. Britain was largely forested in this period, although did witness some land clearance. It remains unclear to what extent the Kentish area was deforested in the Early Neolithic, although it appears that widespread forest clearance only took place on the chalklands of south-east Britain much later, in the Late Bronze Age. Environmental data from the area around the White Horse Stone supports the idea that the area was still largely forested in the Early Neolithic, covered by a woodland of oak, ash, hazel/alder and Maloideae. The tomb building tradition Across Western Europe, the Early Neolithic marked the first period in which humans built monumental structures in the landscape. These were tombs that held the physical remains of the dead, and though sometimes constructed out of timber, many were built using large stones, now known as "megaliths". Individuals were rarely buried alone in the Early Neolithic, instead being interred in collective burials with other members of their community. The construction of these collective burial monumental tombs, both wooden and
