Bipedality in Humans 1
Evolution of Bipedality in Humans
Bipedalism is a capacity, mostly associated to humans, to use two legs in locomotion.
Its origin has been given importance and served as a topic of long debate among experts due
to the possibility that this form of locomotion gave way for the development of modern
human characteristics. Thus, a lot of theories were proposed and established in order to
provide the logical explanation on its origin and development. The burden of dealing with
this classical issue lies on the fact that locomotion is an activity that can not be fossilized.
However, the Australopithecus afarensis fossils, the earliest hominid from Ethiopia and
Tanzania, were found to live 3 million years after the appearance of hominid lineage around
6.5 million years ago (“Bipedalism,” 2000). These fossils in a way may serve as evidence not
only of bipedal locomotion but also hominid dental characteristics similar to apes.
Bipedalism enabled humanoids to create tools used for the sustenance and defense of
life and is also observed in other animal species (Dhingra and Jablonski, 2004). This trait is
