In research findings published in March in the journal Nature, an inter- national team led by the University of Adelaide’s Australian Centre for Ancient DNA (ACAD) and Dental School, with the University of Liverpool in the United Kingdom, revealed the complexity of Neanderthal behavior, including dietary differences between Neanderthal groups and knowledge of medication. “Dental plaque traps microorganisms that lived in the mouth and pathogens found in the respiratory and gastrointestinal tract, as well as bits of food stuck in the teeth — preserving the DNA for thousands of years,” said lead author Dr. Laura Wey- rich, ARC Discovery early career research fellow with ACAD. “Genetic analysis of that DNA ‘locked- up’ in plaque represents a unique win- dow into Neanderthal lifestyle — reveal- ing new details of what they ate, what their health was like and how the envi- ronment impacted their behavior.” The international team analyzed and compared dental plaque samples from four Neanderthals found at the cave sites of Spy in Belgium and El Sidrón in Spain. These four samples range from 42,000 to around 50,000 years old and are the old- est dental plaque ever to be genetically analyzed. “We found that the Neanderthals from Spy Cave consumed woolly rhinoceros and European wild sheep, supplemented with wild mushrooms,” said Professor Alan Cooper, director of ACAD. “Those from El Sidrón Cave, on the other hand, showed no evidence for meat consump- tion, but appeared instead to have a largely vegetarian diet, comprising pine nuts, moss, mushrooms and tree bark — showing quite different lifestyles be- tween the two groups. “One of the most surprising finds, however, was in a Neanderthal from El ” See PLAQUE, page A3 Permit #1396 Bellmawr, N.J.
