The History of Hominid Evolution Essay - 1049 Words

What evidence shows the changing from the early hominids to the modern humans? Throughout the human evolution body parts like legs and harms have changed for the better. By the early hominids being biped, meaning they are able to stand and even walk on two feet, it helped them to be able to do more things like getting around more and help with their tool making and hunting. A lot of the fossils discovered were found in the Great Rift Valley in East Africa, which contained many different lakes and small rivers. For many years researchers have been finding new species. These species have been named Australopithicus, robust australopithecines , Orrorin tugenensis, Homo habilis, Homo erectus, neanderthal, and Homo sapiens. These early†¦show more content†¦The Orrorin tugenensis was found with thigh bones. And the Orrorin tugenensis had small teeth like the Australopithicus. The robust australopithecines or paranthropines had a curved face with a arch for the cheek bones that are formed by connecting the zygomatic and the temporal bones together. The robust australopithecines had a bone ridge on top of their skull called a sagittal crest, which is also attached to the jaw muscles. They had a flexable base just above were their jaw bone connected to their cheek bone. With their really large back teeth (below the cheek bone) the robust australopithecines fossils were known to the researchers as the â€Å"nutcracker man†. They used these really large back teeth to eat tough foods and nuts. And their teeth in the front were smaller. The Homo habilis was known as â€Å"the skilled human or handy man† (Standford 273). They got this name because they made tools. Homo habilis have a brain size of aproxamiltly 509 cc to aproximitly 775 cc. They also have a encephalization quotient (EQ) of about 2.73 to 3.38. Homo erectus was first found in Africa and the fossilized remains dated 1.8 and 1.0 million years old. The Homo erectus traits are very similar toward the modern human traits. Homo erectus brain size was smaller than the Homo sapiens. Homo erectus had a brain size of approximately 650 cc and Homo sapiens had a brain size of approximately 1251Show MoreRelatedBipedalism : What Is That All About?1114 Words   |  5 Pages Bipedalism: What is that all about? The issue at hand in these articles is the evidence for the development of bipedalism in hominids. Bipedalism seems to be one of the most important factors in the evolution of mankind and therefore the surrounding debate is rife with various hypotheses as to the background of this development in hominid evolutionary history. Although each of the three articles reviewed in this essay make different arguments, each seem to be cogent in their own way and do seemRead MoreMasters Of The Planet By Ian Tattersall1027 Words   |  5 Pagesof Natural History in New York. Tattersall was born in 1945 in the United Kingdom, and grew up in east Africa. He trained in archeology and anthropology at the University of Cambridge, and earned his PhD from Yale University in 1971. Tattersall’s main focus over the course of his career has been on three areas; the human fossil record, the study and ecology of Lemurs in Madagascar, and finally on human cognition. He brings to the issues a lifeti me of expertise in hominid evolution, as well asRead More Human Evolution Essay1020 Words   |  5 PagesHuman Evolution   Ã‚  Ã‚  Ã‚  Ã‚  When people take a look at African history in general many topics and ideas come to mind. How the people of Africa lived, how they developed civilizations and cultures, and how their oral traditions came about are just a few examples. When I am trying to learn about different groups of people and different areas of the world I most likely start at the very beginning of their existence.

Think of it, as a trial to see which will win, creation or evolution. It has been the most argued debate in all of history, but creationism is more logical than evolution. To first understand what creation is about, we have to know what creation is. The Bible defines creation as the action by God that brought the universe and all its contents into being. The BibleRead MoreThe Role Of Physical Anthropology On Human Evolution843 Words   |  4 PagesThroughout history there has always been questions that have been difficult to answer when pertaining to the human species. Where do humans come from? How have they become so advanced, when compared to that of similar species? Many have sought to find out the answer, and have found some clues that can be quite interesting. The best way to answer these questions is through the idea of evolution. Evolution, from a biological perspective, is the belief that changes within species takes placeRead MoreEssay on The History of Human Evolution1517 Words   |  7 PagesThe History of Human Evolution By definition, human evolution is the development, both biological and cultural, of humans. Human ideologies of how the evolution of man came to be is determined by cultural beliefs that have been adopted by societies going back as far as the Upper Paleolithic era, some 40,000 years ago. Through the study of paleoanthropology, we have come to determine that a human is any member belonging to the species of Homo Sapiens. Paleoanthropologists, while studyingRead MoreThe Origin of Language in Human Evolution Essay1209 Words   |  5 Pagessystem were capable of developing (Ulbaek, 1998). Whereas other animal species communicate through vocalised sounds, songs, or gestures specially primates such as apes. Similarly gestures and hand gestures were the form of communication used by early hominids, but Homo habilis and Homo erectus started to use vocalisations and decreasing the frequent use of simple hand gestures for communication. Humans developed a spoken linguistic system which is used to express separate and distinct thoughts.

The following section will cover aspects on which Darwin’s theory was transformativeRead MoreHuman Evolution: Myth or Fact1301 Words   |  6 PagesThe debate of human evolution being fact or fiction has been around for hundreds of years. Evidence of human ancestry has been found in many parts of the world and these fossils found have been proven to be human. The parts of the world include Eurasia and Africa. Although fossils are found in Eurasia, the human ancestor the Hominoidea has been traced back to the Miocene epochs, which were 23 to 5 million years ago. The Hominoidea is a super-family, which contains many species that are existen t todayRead MoreThe Evidence For The Earliest Use Of Fire By Humans1429 Words   |  6 PagesCritically Examine the Evidence for the Earliest use of Fire by Humans Fire, the source of heat and light, plays an important role throughout the history of humans, and has been closely integrated into many stages of their evolution. The ability to control fire became a turning point in human evolution, which enabled early hominids to cook food, according to Richard Wrangham ‘s â€Å"Cooking Hypothesis†, cooking food increased food efficiency so that human ancestors spent less time foraging, chewing,
