More recent analysis of Shanidar 1 by Washington University Professor Erik Trinkaus and Dr. Sébastien Villotte of the French National Centre for Scientific Research confirm that bony growths in his ear canals would have resulted in extensive hearing loss. These bony growths support a diagnosis of diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier's disease. This diagnosis would make Shanidar 1 the oldest hominin specimen clearly presenting this systemic condition.The researchers found these bone growths in multiple places all over the partial skeleton.
