epa05983961 An undated handout photo made available on 23 May 2017 by the University of Tuebingen shows the lower jaw of a 7.175 million-year-old Graecopithecus freybergi specimen nicknamed 'El Graeco' found in Greece. According to a publication in the PLOS ONE scientific journal on 22 May 2017, 'researchers investigated two fossils of Graecopithecus freybergi and came to the conclusion that they belong to pre-humans. Their findings further indicate that the split of the human lineage occurred in the Eastern Mediterranean and not - as customarily assumed - in Africa.'
