  • Homo Ergaster

    Homo ergaster, meaning ‘workman’, lived in eastern and southern Africa around 1.5 million years ago. The ergaster had a good run for about 500,000 years, until vanishing from fossil records 1.3 million years ago. Homo ergaster was discovered in 1949 somewhere in southern Africa by prominent South African hominin paleontologist, John T. Robinson. Researchers have argued back and forth on the the idea that Home ergaster is a valid taxon due to the similarities between ergaster and erectus. Some differences that distinguish ergaster from erectus is: Greater development of the mandibular symphysis, broader nasal bones and nasal opening, Home ergaster is considered to be the first hominid to use a proto-human language due to the presence of the the cervical vertebrae and markings of the digastric muscle located in the mandibular symphysis. However, the cervical vertebrae reveal that the spinal cord was thinner than in modern humans. This may indicate that this species had limited speech capacity due to the lack of nerves needed for the complex control of breathing while speaking.Even if ergaster never formed a form of verbal language, the well developed brain could have allowed symbolic communication.…

  • Hominin Evolution Theory

    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…

  • Hominin Expansion

    expansion throughout most of Africa occurred with Australopithecines, Paranthropus, and early Homo habilis. Each species was advancing, and adapting to their various habitats. However, a new homo was entering the playing field, which was not only biologically modern but was capable of creating tools. This new species is known as Homo ergaster/erectus, and they were on the verge of breaking out into new territory. This group would soon leave the cradle of Africa and traverse to Asia, and…

  • Homo Naledi Analysis

    The article I found is on the discovery of Homo naledi. Happened upon only by chance, the struggle to find Homo naledi was as hard as placing it with either Australopithecus or Homo. I found this article interesting because the discovery of a potentially new species could give us a clearer picture of our ancestors. We may never know the complete story, but as long as we keep on researching and exploring new ideas, our understanding will grow. In addition to adding to our understanding of…

  • Essay On Homo Erectus

    this paper, I am going to discuss the Homo erectus, Homo Heidelbergensis, and Archaic Homo sapiens. The paper will make comparative analyses of the individual species and point out why I believe they deserve to be categorized as distinct species instead of a one species that has different characteristics due to geographical differences. The Homo Heidelbergensis are approximated to have lived about 600,000 years ago. This simply means the Heidelberg Man and was derived from the German city…

  • Richard Wrangham's Catching Fire

    cooking and how it led to the evolution of the hominin ancestors into modern humans in his book Catching Fire: How Cooking Made Us Human. In it he addresses many questions and theories about his hypothesis. Some of the more important ones are the influence of food on inter-birth interval, the avoidance of starvation by Homo sapiens ancestors, our ancestors’ loss of body hair, and the influence of Darwinian selection for social tolerance and cooperation. Wrangham’s hypothesis provides answers for…

  • Australopithecines

    In the same area but from 1.9 to 0.027 million years ago, Homo ergaster also roamed around. Even though they shared the same geographic location, they each represent very different phases of the evolution to what we are today. It would therefore be interesting to see how they differed, based on the physical traits of certain representative fossils, when it comes to body size, bipedalism and other cranio-dental features. Height is one of the most explicit physical differences between the…

  • Homo Sapiens

    evolution from 2 milion years ago to 20,000 years ago. Throughout this research paper, it shows the analyze the ecological conditions and behavioral patterns that contributed to the evolution of Homo habilis, Homo erectus, Archaic Homo sapiens, Neanderthals and early modern Homo sapiens during that period of time. First of all, the Pleistocene Epoch is the main point of this paragraph. The Pleistocene Epoch takes place from 2.6 million to 15,700 years ago. it is considered as the reason of…

  • Giorgio Agamben's Writing Of Sovereign Power And Bare Life

    This figure is called homo sacer, and in Agamben 's theory, it is a person whom one could kill with impunity (without consequences) (Agamben, 8). He compares this person to the living dead because although they are physically alive, they could be killed at anytime (theoretically) as they have been regulated by sovereign power to be outside the law (Agamben, 8). These individuals, although they can be killed because they are not a citizen, cannot be sacrifices in religious ceremonies because they…

Antony had to ask Brutus for permission to speak at Caesar’s funeral. His despairing emotion and speech drawed the crowds special attention. Antony speech does not show any praise of caesar but does show sympathy and memorable memories that caesar did for his town. This whole situation sums a complete catastrophe. If…
