Research conducted by a University of Oklahoma anthropology professor has been named one of the top 100 stories of the year by Discover Magazine.
Christina Warinner directed a study of dental plaque from four Medieval skeletons. She published her research in Nature this past February. Discover Magazine was so impressed it’s ranked it the 69th best science story of the year and will feature it in an article in its January/February issue of the top 100 stories of of 2014.
According to OU, Warinner’s study found evidence of ancient DNA from wheat, pork, mutton, and a plant belonging to the mustard family. She also found ancient protein from cattle, sheep, and goat milk.
The picture above shows a human jawbone that dates to the 1st-4th century from York, UK. Dr. Warinner doesn’t know the sex but says the person was in their 20s or 30s when they died. You can clearly see the build-up of dental plaque on the teeth. Dr. Warinner says this particular example tested positive of milk proteins.
