Recent genomic data have revealed multiple interactions between Neanderthals and modern humans, but there is currently little genetic evidence regarding Neanderthal behaviour, diet, or disease. Here we describe the shotgun-sequencing of ancient DNA from five specimens of Neanderthal calcified dental plaque (calculus) and the characterization of regional differences in Neanderthal ecology. At Spy cave, Belgium, Neanderthal diet was heavily meat based and included woolly rhinoceros and wild sheep (mouflon), characteristic of a steppe environment. In contrast, no meat was detected in the diet of Neanderthals from El Sidrón cave, Spain, and dietary components of mushrooms, pine nuts, and moss reflected forest gathering. Differences in diet were also linked to an overall shift in the oral bacterial community (microbiota) and suggested that meat consumption contributed to substantial variation within Neanderthal microbiota. Evidence for self-medication was detected in an El Sidrón Neanderthal with a dental abscess and a chronic gastrointestinal pathogen (Enterocytozoon bieneusi). Metagenomic data from this individual also contained a nearly complete genome of the archaeal commensal Methanobrevibacter oralis (10.2× depth of coverage)-the oldest draft microbial genome generated to date, at around 48,000 years old. DNA preserved within dental calculus represents a notable source of information about the behaviour and health of ancient hominin specimens, as well as a unique system that is useful for the study of long-term microbial evolution.

Wood charcoal (anthracological) remains accumulated in archaeological deposits provide a valuable tool for reconstruction of past local vegetation and its use. They can offer evidence complementary to pollen analysis or be the main source on past vegetation change in areas where no pollen preservation is available. The current study assembles the anthracological evidence from 18 Neolithic sites situated in the zone spanning between the Lower Danube plain and the Aegean coast. This evidence is presented within the broader archaeological and paleoecological context of the region and in cal. years BC and/or BP. The data is interpreted in terms of land-use related to woodland management and exploitation of woodland resources during three chronological phases which could be distinguished within the Neolithic of south-eastern Europe: a) 6500-5800 cal. BC, b) 5800-5500 cal. BC, and c) 5500-4900 cal BC). The main vegetation type targeted by the Neolithic population were the thermophilous, mixed deciduous oak communities, which contained a rich and diverse undergrowth of light-demanding and fruit/nut bearing trees, shrubs and herbs. Those plant communities were the major source of fuel wood, forest pasture, fodder, gathered fruits, etc. The analyses indicate stability and sustainability of the firewood procurement and woodland management practices for the whole considered period and further suggest that the Neolithic land-use strategies favoured the rich and often fruit-bearing undergrowth of the oak forests and woodland.
