Abstract: The taxonomic debate on the phylogenetic coherence of Homo erectus as a widespread intercontinental species is constantly put forward, without major agreements. Differences between the African and Asian fossil record as well as differences between the Chinese and Indonesian groups (or even within these two regions) have frequently been used to propose splitting taxonomical alternatives. In this paper, we analyze the endocranial variation of African and Asian specimens belonging to the hypodigm of H. erectus sensu lato, to assess whether or not these groups can be characterized in terms of traditional endocranial metrics. According to the basic endocast proportions, the three geographic groups largely overlap in their phenotypic distribution and morphological patterns. The morphological affinity or differences among the specimens are largely based on brain size. As already evidenced by using other cranial features, traditional paleoneurological metrics cannot distinguish possible independent groups or trends within the Afro-Asiatic H. erectus hypodigm. Endocranial features and variability are discussed as to provide a general perspective on the paleoneurological traits of this taxon.
