One of the many theories that Anthropologist are trying to answer is whether bipedalism or cranial capacity came first in the human ancestry. During recent discoveries, the fossils illustrate that bipedalism came first then the increase of human cranial capacity. Why was it important to be able to walk on two legs instead of the usual four? The evolution of bipedalism enables the human ancestor to use their free hands to create tools which was stated in earlier arguments. Some other arguments state that standing tall makes the primates look more intimidating to other primates. Also, an advantage of walking on two legs included easier food carriage and moving infants to a safe place to feed. The discovery of Ardipithecus ramidus “Ardi” in Ethiopia
