The skull of a Minoan microcephalic was found in the excavations of Zakros, preserved and studied by Dr A. Poulianos. It belonged to a man of 20 years of age, who most probably was member of the Minoan dynasty. Its cranial capacity is of about 530 cc and reflects a genetic diversion connected to long terms isolation and endogamy of Minoans. Thus neither Cretans, nor members of the Minoan dynasty were immigrants from elsewhere, but a result of local evolution. During the military junta, in 1971, it was given to Vienna Museum for "study". It returned to Greece in 1997 after a juridical straggle of the Anthropological Association of Greece. For the benefit of science we urgently appeal to the world scientific community to assist us in protecting the Greek findings from colonial attitudes.
