Biological anthropologist Dean Falk did not expect to see anything like that when she got to work on models of
hobbit skulls at Florida State University in Tallahassee.
«I think [Obendorf's team] is dead wrong on the size of the pituitary fossa,» he says, given his own inspection of a cast of the inside of
the hobbit skull.
The researchers also noted that the pituitary fossa, a notch in the skull that houses the pituitary gland, was enlarged both in the single
hobbit skull and in cretins.
More hobbit fossils are needed to settle the matter; (2) Ralph Holloway (Columbia University) states that although
the hobbit skull may not have microcephalic morphology (shape), it does seem to indicate other brain abnormalities; (3) another researcher states that the size sample in the study was too small.
Falk and her team claim that
the hobbit skull indicates that its brain does not resemble the microcephalics, but instead resembles normal human brains.
It should have had at least thirty specimens for comparison, including some aboriginal peoples (pigmies) living in the region where the hobbit was found; and (4) since the one
hobbit skull available for study was an adult, the study should not have had five microcephalic children among the nine microcephalics used for comparison (Science, 2 February 2007, p. 583).
