This paper provides a background to Neanderthal presence in Western Mediterranean Europe. Habitual tool-use underpinned human survival in late Early Pleistocene western Mediterranean Europe. By the onset of the early Middle Pleistocene, early humans (descendants of Homo antecessor in all likelihood) were exploiting diverse biotopes, sometimes (perhaps often) attaining primary access to large game, and deploying a variety of stone artifacts and rock types, which implies not only manual dexterity but also technical competence and cognitive versatility. Late Early Pleistocene human behaviour foreshadowed that of Middle Pleistocene pre-Neanderthal humans whose background conceivably had deep regional roots. By the mid-Middle Pleistocene Homo heidelbergensis, some of whose anatomical features herald Neanderthal morphology, was exploiting a wide range of natural resources in western Mediterranean environments, including small game and plants. Neanderthal morphology began to emerge during the second half of the Middle Pleistocene, accompanied by increasing technological diversity and an expanding variety of small tools, conjecturally favoured by hafting, perhaps following development of wooden spears (or other tools) and adhesive and binding technologies, and generation and heat-control of fire (which undoubtedly was necessary for activities inside Bruniquel cave). By the onset of the last interglacial period, Neanderthal morphology and Mousterian artifacts are widespread, and there are indications of coordinated retrieval and treatment of body-parts of large ungulates.
