Answer
Rudolf Virchow, a German physician and anthropologist, believed that the original specimen of Neanderthal man was a deformed human. He argued that the Neanderthal was a type of human with a disease, such as rickets or syphilis. This belief was based on Virchow's observations that the Neanderthal skull had a number of features that were not present in modern humans, such as a large brow ridge and a receding chin.
