The earliest evidence of habitation in Greece comes in the form of a skull found in the Petralona Cave in Halikidiki. The cranium has been difficult to date, with some estimates indicating that it is about between 300,000 and 400,000 years old.
While questions abound regarding the exact age and the species of the cranium, it has been classified as a hybrid between “Homo Erectus, the first hominid to migrate out Africa, and Homo Neanderthalensis, the early human that dominated Europe and the Near East before the advent of our own species. (Runnels & Murray, 15).
