The question as to whether the hobbit was human or another species remains controversial. Some scientists claim the hobbit was a diminutive human that
suffered from some type of disease that causes microcephaly, which results in abnormal growth of the brain and causes the cranium to be much smaller
than the normal human cranium. But Dr. Baab and co-author Kieran McNulty, Professor of Anthropology at the University of Minnesota, believe their
findings counter the microcephaly theory.
