    Reading Response to White et al.: Ardipithecus ramidus and the Paleobiology of Early Hominids. In the article, Ardipithecus ramidus and the Paleobiology of Early Hominids, by Tim D. White et al. , the Ardipithecus ramidus specimen ARA-VP-6/500 from the Aramis vertebrate paleontology locality 1 (ARA-VP-1) expedition is examined in depth. The ARA-VP-1 is located in the Middle Awash and expands into the Central Awash Complex (CAC) with different localities, numbered from 1 up. The Middle Awash and CAC are important because the Middle Awash has been dated from the Late Miocene to the Pleistocene, and the CAC has been dated with strata from about 5.55 to 3.85 million years ago. The article has an in-depth description about the site locality. Including…

    insight of our ancestors. Ardipithecus fossils were a crucial find to the field of archeology, which created new suggestions concerning features that associated them with modern Homo sapiens and primitive apes. The structure of the Ardipithecus has provided information which separates…

    Introduction        As time has passed by, the size of the cranium changed. With that being said, the size of the cranium changed in result of better nutrition. On another note, the width of the pelvis changed as well. In that case, the width of the pelvis changed in result of its bipedality. Therefore, bipedality determines whether or not a genus homo can walk, run, as well as their ability to create tools in order to survive. Ardipithecus ramidus…

    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…

    Advantages Of Bipedalism

    At some point between apes and Ardipithecus, a mutation must have occurred that allowed bipedalism to become a reproductive advantage (Kottak, 2015). Gene flow is the exchange of genes between populations (Wilreker, 2016). Gene flow and interbreeding allowed the favorable trait of bipedalism to spread and multiply. Genetic drift is the change in gene frequencies as a consequence of random variation rather than natural selection (Wilreker, 2016). Individuals within the population without the…

    ardipithecus boisei is 18.5, homo erectus is 35.71, homo habilis is 33.6, homo heidelbergensis is 26.1, homo neanderthalensis is 25.5, homo sapiens is 36.77, and sahelanthropus tchadensis is 18.5. The fact is if the opisthion index is less than 15, then that organism walks with two feet. We can conclude that all the organisms are bipedalism because none of the opisthion index is less than 15. The evolution might had happen because the ecosystem appear many more animals that can harm human…

    Human Evolution For many years people have wondered how the human evolution started and why are we different from other species. Science brings us to new knowledge of how humans evolved in this world and the transition of apes to humans. The Human family tree starts from the Ardipithecus groups about 6 million years ago, the next one is Australopithecus group is about 4 million ago, the third one is paratroops group is about 3 million years ago and the last one is the homo groups is…

    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 closest link to other primates. Christianity says that humans are only six thousand-years-old. Evolution was introduced by a…

    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…

    other hand, splitters suggest that species that dispersed around the globe, they population divergence happened and thus variation increased among them. Splitters theory asserts that Homo erectus became isolated reproductively and each species evolved independent of each other and splitters follow cladogenesis which refers to diversifying selection and it divides species into more branches. Splitters and lumpers agree on grouping, but they disagree on what the differences mean. The difference in…
