    Bipedalism Research Paper

    • 1141 Words
    • 5 Pages

    Introduction The purpose of this paper is to inform the reader about the evolution of the first hominids and to look at some of the reasons that they became bipedal. From there, expand on what evidence has been found to support these hypothesis, and finally look at how these changes created both biological and geographical difference in the sub-species of hominids. This paper will detail each species in a high level overview so that the reader may gain a better perspective of what each species looked, acted, and lived like in its time. Bipedalsim and early bipeds Looking at what bipedalism meant for the early hominid was crucial when looking at survival in a new and changing world. Bipedalism meant that the hominids began to stand on two legs. This was a very important adaptation as they came down from the trees and started life in the savannahs. One of the changes that facilitated this was the foramen magnum or the hole in the base of the skull from which the spine attaches. As it moved downward it allowed for the skull to be held up right when hominids began to walk. Some of the earliest bipeds were Sahelanthropus tchadensis, Orrorin tugenesis, and Ardipithecus ramidus. A. ramidus represents a less-specialized grade of hominine organization than the fully bipedal australopithecines. For instance, judging from Ardi’s mosaic-like foot skeleton, although she walked bipedally when on the ground, she retained an apelike opposable big toe (hallux) and also climbed trees.…

    In 1972 Maurice Taieb, 40, of France's National Center for Scientific Research, and Donald Carl Johanson, 34, of Case Western Reserve University and the Cleveland Museum of Natural History, discovered stone instruments going back 2.6 million years in the Afar area of Ethiopia. After two years their group made a considerably more sensational disclosure. On November 24, 1974, Donald Johanson and his understudy Tom Gray were reviewing a site named Hadar in the Afar area of Ethiopia, East -Africa…

    Creationism is the belief that the universe along with everything in it was created by acts of divine creation. A good example would be how the Christians believe that God is the creator of all things. Evolution is the process of different species developing and diversifying over a period of time to adapt to their environment. A good example would be us. According to scientists we have ancestors that trace back to six million-years-ago to a group called the Ardipithecus group which is our…

    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,…

    The primates that possess characterics like bipedalism, smaller canine size and bigger brain size are hominins. Humans are the modern Hominins and the fossils reveal that several species of hominins are extinct. Homo is a type of Hominin that lived around 1.9 m.y.a and it is the immediate predecessor of Homo sapiens. Paleontologists and archeologists have classify each time they discover new fossils that have primates and or derived characteristics. The two groups of anthropologists are lumpers…

    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,…

    Every specie in the earth is came from an ancestor. Their ancestor change over time to adapt to the environment, this theory knew as evolution. Scientist called it a theory not because it just a belief that can’t be prove, but they already found many piece of evidence to prove that this theory is actually true. The three trustworthy evidence for this theory is fossil evidence, homologies, and biogeography. Fossil evidence are the evidence that found in the fossil of a species. Scientist…

    Charles Darwin is very well known for his theories on evolution and most importantly his three principles of evolution by natural selection. Darwin’s first principle is that a variation exists within populations. Some examples of variations include body size, bone structure, tooth size, hair thickness, shape of the rib cage and position of the foramen magnum. In Evolution, Dr. Alice Roberts provides examples of early hominins and how their physical makeups were reconstructed by archeologists…
