Embryogenic cranial evidences in fossil hominids, taxonomical and phylogenetical implications in human palaeontology

After a long period focused on East Africa, the debate on the origins of Anatomically Modern Human, Homo sapiens sensu stricto, as well as that of the oldest species of the genus Homo, is again topical. This focus is due for the most part to the outstanding conditions for fossilisation and excavations of plio-pleistocene fossils and, on the other hand, to the increasing research programmes in those areas of the Old World. North Africa (Ain El Hanech, Algeria) and South East Asia (Homo erectus child from Modjokerto) raised also the question of the great age of Homo genus (1,8 Myr), but this is during the last decades that the geographic areas expanded from the Arabic peninsula to Southern Europe, India and China (Majuangou, 1.66 Myr (Zhu et al. 2004, Huang and Zhang 2007)
