“…The fossil evidence provides some indication that humans have changed their mating systems through time. The robust and gracile australopithecines, as well as H. erectus, all seemingly displayed much larger sexual dimorphism in body size than modern humans (see above), but clear inferences of their sexual behavior are limited by conflicting evidence from their canines, questions of taxonomic assignment, and methodology [Gordon et al, 2008;Lee, 2005;Plavcan, 2000;Reno et al, 2003]. Our data certainly do not resolve this longstanding paleoanthropological debate, nor can they definitively conclude how important, if at all, sperm competition was in hominin evolution, but we believe that they may add some useful information.…”

“…Cephalometric studies have revealed craniofacial differences between different populations, ages, and sexes. [12] In various populations it is possible to observe many variations of cephalometric patterns within homogeneous groups. [35] Hanihara applied distance analysis and factor analysis to 23 craniofacial measurements in 1802.…”

“…Such a conclusion, however, does not allow us to know enough about sexual dimorphism in extinct hominids so that it is possible to infer without a doubt whether the first Homo fossils are more or less sexually dimorphic than modern Homo sapiens. Nowadays, Australopithecus is more accepted as less dimorphic than thought before, which indicates that conclusions about sexual dimorphism in extinct hominids are still open for discussion (Lee, 2005;Reno, et al, 2003Reno, et al, , 2010.…”
