What Is The Vigilance Hypothesis
The vigilance hypothesis states that early hominids would benefit from standing upright because they would be able to see over the tall savanna grass (Dart, 1926). Bipedalism will allow the head to be upright and increase viewing distances, this would allow them to see incoming predators. The other senses would also be elevated with bipedalism, they would be able to better hear and smell as well. The main problem with this hypothesis is that animals do not need to be bipedal to display vigilance behavior (Friedman,

    Becoming Human Episode 1 Analysis

    The vital clue that the "Toumai" fossil is bipedal is how the skull connects to the spine. Researcher Michele could confer that by the shape of Toumai's skull. If the skull is placed on a neck of an ape that walks on all fours its eyes point down ward (not correct). If the skull is placed on an upright spine of a biped its eyes point straight ahead; for Michele this proved that Toumai walked upright.…

    The Taung Child

    The Taung child was found with the whole face and lower jaw complete with many teeth (Figure 2). As well, most of the cranium portion was intact with a natural endocast of the braincase (Dart, 1925). Only in very rare cases does a fossil have an endocast. Dart focused on the features of the brain because he saw signs of cerebral advancement towards humans. The foramen magnum was positioned upright from the spinal cord which is present in bipedal locomotion in an upright position. When the foramen magnum is positioned directly above the neck, it allows carriage of the head and the ability to look downwards. Four-legged creatures walk with their eyes facing forward, thus the foramen magnum is positioned at the rear of the skull. The bipedal motion…

    Summary: Key Innovation In Human Evolution

    Key innovation in human evolution is the development of bipedalism and gradual increase in size of brains. The evolution might have occurred due to change in climate and environment which lead to reduction and replacement of trees with grasslands. Due to presence of large numbers of trees, it was easier for our ancestors to have quadrupedalism instead of bipedalism, so that they can climb on trees and move from one place to another. But with the decrease in number of trees, requirement for bipedalism increased. In an article by Wayman E. (2012), it has been mentioned that Lucy had the anatomy of bipead. Lucy belongs to Australopithecus afarensis. It is estimated that Lucy lived 3.2 mya. Her pelvis was broad and she has thigh bones which were…

    The author of the article “New Perspectives on the Evolution of Bipedalism,” Allison S. Brookes makes a compelling argument that the reason humans evolved to walk on two legs was the need to be able to outlast the animals that they were hunting. Early Hominines did not have adequate ways of killing large game up close, they did not have bows and arrows, and much less guns to hunt with. The author argues that because of this, they had to evolve to be able to run long distances to instead kill the animal they were hunting through its dehydration and overheating.…

    Compare And Contrast Primates

    The characteristic that separates primates from hominids is bipedalism; means walking in two feet. These characteristics can be seen in the skeletal structures that have different traits that are: the pelvis is vertical, the spine is curved in an S shape and the last trait is that the arms are shorter than the legs.…

    A New Understanding of Neanderthals

    From the early skeletal analysis of the Neanderthals they were depicted as "bent-kneed and not a fully erect biped." However, we now know that Marcellin Boule, the French paleontologist who made the analysis, may have misinterpreted the specimen as having a hunched spinal posture, when it was really due to a conditional called "osteoarthritis" (Jurmain, 257). This degenerative bone-disease is commonly seen in modern humans who suffer from a deficiency in calcium. It is easy to see the effects of this condition in the elderly who suffer from it. Although upright, their spines are curved downward and they are severely hunched. In this light, it is easier to imagine that the Neanderthals were more like…

    How Does Primate Influence Human Behavior

    Since humans and other primates share a variety of characteristics, other primates provide important observations about early humans. Homologies between hominids and other primates enhance to behavior because the physiological and cognitive formations that manage to control human demeanor are likely related to those of other primates than to members of other taxonomic groups. The reality of this broad collection of homologous traits, the commodity of the average evolutionary history of the primates, means that nonhuman primates give beneficial examples for understanding the evolutionary ancestry of hominid morphology and for resolving the basis of human nature.…

    Bipedalism Research Paper

    It’s probably harder and we cannot run fast doing so just because we have evolved out of being quadrupeds. But looking at the fastest animals in the world, most of the fastest animals run on four legs. I’m not saying that we should run on all fours but that speed was no longer a necessity in our survival. There are many disadvantages of being biped as well as advantages. I have noticed that almost all of these disadvantages are directly correlated with the advantages. Basically, everything in our evolution process was a system of trade-offs. A perfect example of this is shown here, “Still other advantages of Bipedalism would have enhanced survivability. With their heads up well above the ground, bipeds are able to spot predators before they get too close for safety.”, which can be compared to, “ Bipedalism makes an animal more visible to predators, and exposes its ‘soft underbelly’.” See how it’s all a system of trade-offs? I could show many more examples, but you get the point. More disadvantages of Bipedalism are limiting the ability to run faster or change direction quicker when running. “Quadrupedal baboons and chimpanzees are 30 – 34 percent faster than…

    The Evolution in Primate Locomotion and Body Configuration

    Primates first evolved from the trees of tropical forests, later to the ground. Through the times of promisians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information since we are the part of occurring changes as well. Throughout the evolution owing to the transforming environments interacting with natural selection, primates developed their own ways to move better (meaning changes in locomotion) with different types of bodies (meaning changes in body configuration).…
