Searching for dental caries in South African fossil Hominins.
[sciencythoughts.blogspot.com]
Dental caries (the formation of cavities in teeth through decay of the enamel, through the activities of Bacteria) is common in many modern Human populations, and is generally associated with a diet rich in plant-derived foods rich in sugars and starches. The presence of widespread dental caries in Human populations is generally thought to have come about during the Neolithic, when the cultivation of grains was adopted, providing a source of food reliable enough to allow populations to rise and more complex cultures to develop, but at the same time exposing people to the hazards of a starch-rich, grain-based diet. If this is the case, then instances of dental caries should be relatively rare in Pleistocene Humans, as well as in other Hominin species.
