The skulls found on the island of Flores belonged to a distinct species, that is, the Homo floresiensis is really a species. This is demonstrated by tomography scanners performed on skulls.
The scanner has explained the brain structure of these small hominids, which has been contrasted with other species: With the homo erects, with the chimpanzees, with the man of today...
The result will serve to resolve doubts, since some experts considered that these skulls could be the pygmies or had a malformation (microcephaly).
