Essay On Sahelanthropus

Improved Essays
When looking back on the evolution of man nothing stands out more than the word “bipedalism” this is what kicked us off the ledge to start us on the path of walking upright completely and gave us the dominated figure we all have today. Now let’s take it from the beginning the earliest forms of human beings used to climb tress and would walk on the ground, this use of flexibility allowed early humans to get around in such diverse habitats and also to be able to cope with the many changing climates (Smithsonian Museum). But something happened about 6 million years ago it is shown in the oldest evidence that the first of the earliest humans to become bipedal was known was, Sahelanthropus. It is said that being that Sahelanthropus could walk upright …show more content…
Hip support came late around 1.95 million years ago with the size and also the broad shape of these hip bones of that of Homo erectus are very similar to those of modern humans, this shows that this early form of human species completely stopped climbing to take on full bipedalism as way of getting around. Its till 1.9 millions years ago that early specie of man became fully bipedal with the pelvic and also the thigh bones from the specie of Homo erectus are similar to those of modern humans, this showed that Homo erectus would be able to walk long distances. This ability aloud a very big advantage during this period in time. Then finally around 1.89 million years ago we see that Homo erectus had long thigh bones that allowed them to walks faster and great lengths than earlier humans (Smithsonian

    The hominin evolution theory is the idea of Homo sapiens sapiens (AMHs) evolved from a lineage of hominins in Africa. The purpose of the project is to determine the genus and species of seven skulls discovered by Dr. Musoma in Africa, Europe and Asia, approximate the age of each skull, interpret the evolutionary pathway of each species, and provide evidence for and against the “Out of Africa” theory. The purpose of the project with be completed and evidence on the “Out of Africa” theory will be found. Based upon the information left with each of the seven skulls, the remains can be identified with the appropriate genus and species. For all seven skulls, Dr. T. C. Musoma left the cranial capacity, location and the artifacts, if any, found with…

    In the 1800’s a strange skull was discovered in Gibraltar. The remains were name Homo neanderthalensis or Neanderthals, an ancient primitive form of human. They adapted physically and culturally to the ice age conditions that prevailed during much of their time. 10,000 years later the Neanderthals vanished and has been a mystery. Although some sources considered the Neanderthals were primitive with no language, art, stupid presence and no personality, scientists have discovered that the Neanderthals were actually intelligent and had used language, symbols and art like human.…

    Four million years ago, a few ape like animals that began to walk upright taking the first faltering steps towards becoming human beings. Time and changing, and the struggle for survival continued shaping us. Along the way, social groups became the key to survival, and the human family evolved as pleasure of mating. In their struggle for survival these creatures found saving advantages in a new way of walking.instead of scampering on all fours, as usual, they stood upright and gradually and no doubt unsteadily at first, began to walk on their hind limbs.…

    Our physiology has been compared with those of modern day primates, due to our similar characteristics, which have all been linked to our ancestors. Hands of humans and primates are prehensile, “which means they can grasp objects and we share the ability to brachiate from “branch to branch contain a “reduced sense of smell,” and a “wide range of tooth types [suggesting] an adaptation to a generalist diet” (MacDonald, 2003, p. 325). All of characteristics suggest that our ancestors were arboreal, and we continue to show our ability to climb trees fairly well, however the main feature that has distinguished humans from modern primates has been our ability to walk on both legs, maintaining a sense of natural balance, of which primates lack. Ramapithecines…

    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, seeing their behavior. They watched to see if the chimpanzees grabbed a fistful of tasty treats before someone else got to it, they stuffed the treats in their mouths and hands, running to a safe spot on their own two feet. They were four times more likely to maintain a human posture if treats were rare and there was some competition at hand.…

    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 about 1 million years ago. Ardipithecus kaddaba was discovered in Ethiopia in 1997 by a paleoanthropologist Yohannes Haile-Selassie and was dated to 5.8 million years old. Ardipithecus group is similar to modern day chimpanzees because of the bones and facial structure.…

The physical states observed in the species were primarily ancestral characteristics ranging from the more distinct species, gorilla gorilla, to modern human, homo sapiens, they all had molars, flat face with forward facing eyes. Ancestral/primitive characters are the characters that were present in a common ancestor whereas the derived characters are those type of characters that were not present in the common ancestor. One of the observed characteristics for derived characters are large cranium which gradually increased from the opposing small cranium present in the ancestors.…

    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.…

    What is it to be human? One would think that humans would be experts on the subject, but instead the question seems without answer. The Wisdom of the Bones by Alan Walker and Pat Shipman explores this question by defining the physical and behavioral characteristics of humans and their ancestors. Despite our ability to create clean categories for other animals to fit in, Walker and Shipman reveal that there seems to be something harder for humans to define about ourselves. As is done with any other animal, the logical place to start is with humans’ unique physical traits.…

    Archaic H. sapiens possessed unique features compared with more modern H. sapiens. In contrast to modern H. sapiens, archaic H. sapiens had a longer, lower skull, a larger browridge, a bigger and more prominent face, a wider nasal aperture, a more projecting occipital bone, larger teeth, and very little, if any, chin. The postcranial bones of archaic H. sapiens were also thicker than modern people’s as well (Larsen, 2011). Some hominid skeletons dating to the Upper Pleistocene possess a fusion of those archaic skeletal features as well as modern ones.…

    Evolutionary Relationships of Hominin Species In the study of human evolution, the timeframe that a specific species appeared and lived is a very important aspect to better understand how modern-day humans developed. The oldest of the species in the chart above is Australopithecus afarensis. Australopithecus afarensis appeared roughly 3.85 - 2.95 million years ago; while it more closely resembled an ape, the evolutionary development into modern humans was beginning. Australopithecus afarensis had more humanlike teeth, the canines were smaller than those found in modern apes and the jaw shape was somewhere between the rectangular shape found in apes and the parabolic shape found in humans.…

    Genus Homo Evolution

    • 6 Pages

    Since the emergence of the genus Homo, the hominins went through great patterns of evolution over generations. Through series of adaptations, the genus Homo spread in various geographic locations and eventually emerged as anatomically modern humans. With the allele frequency changes that evolved in the genus Homo, there is key evidence that microevolution led to macroevolution. From speciation to extinction, the modern synthesis helps us explain not only the mechanisms of evolution and the reproductive barriers between species, but also the various social adaptations that changed the hominins over time. From 2mya to ca.…
