Advantages of Bipedalism. There is compelling evidence that point towards climatic changes over long periods reduced forested areas forcing early hominins to get into habitual bipedalism allowing them to range into open landscapes. As a result, walking at normal speeds on level surfaces requires very little muscular activity, making bipedalism more efficient than knuckle-walking or quadrupedalism (McNeill Alexander 1985). Through those years of study, noticing hardly any tripeds or pentapeds, it has been taken into consideration that bipedalism and quadrupedalism are the dominant pedisms.
