Bipedalism

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. Locomotor Efficiency Locomotor…

Bipedalism is something people take for granted. Without conscious thought they put one foot in front of the other and stride forward. While great attention is given to a baby’s first steps, little, if any, attention is given to the advantages of this form of movement. The benefits of walking, running, and standing while using two legs instead of four go unremarked. It is simply natural for humans to travel this way. Humans are not the only animals to use bipedalism, birds and some mammals,…

Bipedalism and Environmental Adaptability Bipedalism as general definition, is the ability of all types of animals standing in two feet. The environmental Adaptability is the way to get used to a habitat and weather. Both of them played an important role in the evolution of modern humans. According to the book “Worlds Together, Worlds Apart” by Robert Tignor, describes the advantages of bipedalism and the environmental adaptations that allowed modern humans to live into two different…

putting Lucy’s pelvis fragments together. He stated that the reason for Lucy’s pelvis to look like an ape’s was because of great pressure on the skeleton caused the pelvis to break. Moreover, due to further fossilization, there were two pieces that bonded into one and triggered these two pieces to fit perfectly. Dr. Lovejoy made a plaster model to the pelvis to restore Lucy’s pelvis to its natural form. After taking out the twist it previously had, the pelvis came to fir perfectly like a puzzle…

believe in Darwinism, that through the process of natural selection in humans over millions of years evolved from the great apes. Despite their brilliant claim, in 1859 there was insufficient physical evidence to prove that man evolved from ape, evolutionist lacked the “missing link” fossils of transitional species between ape and human that would validate the theory of evolution. However, through centuries of archeological discoveries, evolution obtained credibility. In the 1970’s, this process…

Evolution shapes certain characteristics which can be shared by many species of a certain organism. These traits can be related to the four evolutionary trends of hominins: bipedalism, dental change, cranial capacity and material culture. (Gonzalez, pwpt) The three anatomical characteristics of skull one are the teeth and jaw are smaller, the projection of the face and jaw is less than previous hominins and the cranial capacity increases by elongating. The dental change suggests a change in diet…

as a characteristic of an organism that is some way contributes to the organisms reproductive success (Wilreker, 2016). Bipedalism is an adaption of upright, two-legged movement rather than four-legged movement, and the key characteristic which makes early hominins different from the apes (Kottak, 2015). There are many advantages of bipedalism adaption which Scientists have suggested: the ability to see over visual obstacles, to carry items back to their homes, and to limit the body's exposure…

There 's many reasons our ancestors had begun walking around on their two legs instead of running on all fours. Evidence was collected during two trips to Guinea in West Africa, because of the trips, there has been one of several leading explanations for why humans became bipedal (an animal using only two legs to walk) millions of years ago. Researchers from Portugal, United States, Japan and England spent multiple weeks watching chimpanzees in their natural habitats to see how they moved about,…

Two of the most distinct features that separate humans from the other great apes are bipedalism and large brain to body size. But how did these features become so prominent? Approximately 6-7million years ago, the hominid lineage began to separate from the other ape species. Tracing the evolutionary history through fossil evidence explains how early hominids evolved to become today’s most prolific primate species. The goal of this paper is to discuss the physical characteristics that indicate…

Bipedalism is the ability to walk on two legs. This behavior was first associated with apes nearly seven million years ago. During this time period, the jungle Africa started to become barren and lacked enough resources for the apes to continue living as they had. The lack of food in their jungle environment forced them to travel on the ground, however, this led to many problems. While searching for food on the ground, apes were susceptible to predators, they also lacked the ability to transport…
