Bipedalism is one of the Big six events that happened in evolution of humans becoming what we are today. Bipedalism means standing, walking lifting on two feet rather than walking on four feet like the other apes in our Apes category. To understand why humans walk using bipedalism anthropologist must look into the past. One of the most significant fossil for evidence of bipedalism is a fossil named “Lucy”. Lucy was found in Easy Africa. She is an adult female that stood at about three and half feet. Lucy is a significant find because she was the most complete at 40% of her was found, making her the most put together fossil for bipedalism. It is accepted that there is a close relation to environment (Jablonski N. & Chaplin, 1992). Evolutionary change only happens when there is a pressure on the animals to have something change into something else that was working for them just a few years earlier.
Anthropologist are not completely sure as to why there was an evolutionary change. With the acceptance of environment relation, it helps narrow down what could have happened however, there are no clear answers or hypotheses to bipedalism. The hypotheses for the reason why there was an evolution to bipedalism are; Locomotor efficiency, Thermoregulation, Free of the hands, and Visual surveillance.

Quadapedal animals such as apes, use tools and they carry around their offspring by making the offspring holding on to them. Apes also use tools such as sticks to retrieve insects such as acts from the ground and use stones to break open shells of nuts to get the eatable nut inside, yet they do not walk on two limbs all the time. They can walk on two limbs for a short distance but the rest of the times they knuckle-walk. The use of tools and the carrying of tools has no affect them in making them change how they
