The study of the skulls KNM-ER 1470 and KNM-ER 1813, considered the first members of the genus Homo, has raised some debates. While some of researchers maintain that there is only one species, another group argues that there are two species. On one hand these two fossils are still taxonomically undetermined, on the other hand they bring up another problem related to the existence of a genus with multiple species since its beginning, according to the last discoveries. In this paper, we have compared the size ratio between these fossils with ratios established in populations of Homo sapiens, in order to know if they fit into the human standard, considering intra-sexual and inter-sexual variation. Results help to establish whether these fossils correspond to different species or their differences could be related to sexual dimorphism within a single species.
