At least six different Homo species populated the World during the latest Pliocene to the Pleistocene. The extinction of all but one of them is currently shrouded in mystery, and no consistent explanation has yet been advanced, despite the enormous importance of the matter. Here, we use a recently implemented past climate emulator and an extensive fossil database spanning 2,754 archaeological records to model climatic niche evolution in Homo. We find statistically robust evidence that the three Homo species representing terminating, independent lineages, H. erectus, H.

Many cultural assets are in risky situations and they are destined to disappear. Sometimes problems are caused by the anthropic component (e.g. wars) or by natural disasters (e.g. earthquakes and landslides). At other times the cause of deterioration is due to the slow and inexorable action of atmospheric agents and other natural factors present in extreme areas, where preservation of Cultural Heritage is more complex.

The remains that typically compose the human fossil record often bear cracks, damage, and deformations. The recent rapid development of ‘virtual anthropology’ has provided innovative tools to manage, study, and preserve cultural and natural heritage. Such tools include computerized tomography (CT), laser scanning, photogrammetry, 3D imaging, and rapid prototyping. These approaches can contribute to any archaeological context from the discovery of artefacts to research, preservation, and dissemination.
