Asymmetries of Cerebellar Lobe in the Genus Homo

The endocast was paid great attention in the study of human brain evolution. However, compared to that cerebrum, cerebellar lobe is poorly studied regarding its morphology, function, and evolutionary changes process In this study, we define major axis four measurements inspect possible asymmetric patterns within genus Homo. Results show significant asymmetry only observed for length modern humans absent Homo erectus Neanderthals. influence occipital petalia obscure due small sample size H. Neanderthals, while it has a over asymmetries height horizontal orientation humans. Although Neanderthal cerebellum are comparable humans, sagittal closer erectus, which wider than morphological difference between Neanderthals suggested be related high cognitive activities, such as social factors language ability.
