    Jürgen Hummel
    Institut für Tierwissenschaften, Universitat Bonn, Bonn, Germany
    Proc Biol Sci 278:1742-7. 2011
    ..While surprisingly our results do not indicate major seasonal changes in silica ingested, the correlation of faecal silica and hypsodonty supports a scenario of a dominant role of abrasive silica in the evolution of high-crowned teeth...
