Anthropology Fossil Determination, Explanation, and Analysis

Anthropology 2- EXTRA CREDIT duty assignment\n\n carry 1:\n fogey 1 displays characteristics of Australopithecus aethiopicus of due west Lake Turkana, Kenya. This skull shows the obvious characteristics of a really sharp sagittal lie along the pull in of the skull, a actually wide skull in the cheek bea, and an utmost(prenominal)ly hypognathous reject skull and jaw area. The cranial capacity also appears to be littler, suggesting that it is of the earlier hominids.\n\nFossil 2 shows eyebrow ridges and a slender sagittal flush agreeable with military man erectus. The approximately define characteristic, however, is the presence of nuchal torus, a extrusion of organize at the derriere of the skull where muscles are attached to re bear witness the head up, suggesting a systematically bipedal creature.\n\nFossil 3 is a small skull display no sagittal crest or nuchal torus. There are eyebrow ridges apparent and the present is subtlely prognathic. The skull most well resembles the skull worry that of the Taung child (Jurmain 203). The skull of the Taung child, a variety known as the gracile australopithecine, or A. africanus, exhibits smaller brain capacity, accounting for the smaller skull.\n\nThe fourth fossil has a small skull be conveys the characteristics of human beings sapien, therefore may be a child. At the top of the skull, the bone has not in full come together, consistent with children, and very young human beings sapien. The odontiasis are very small but are shovel-shaped like modern pieces teeth, adapted to tear and fire hydrant softer foods than those e consumen by earlier homophile and other hominids. The skull shows little to no prognathism consistent with humans.\n\nSTATION 2:\nFossil 1 at this station showed postorbital constriction, excess bone behind the eyebrows protecting the eyes. The skull showed slight prognathism, which is the protrusion of the jaw and lower skull. I predicted that the skull was Homo erec tus; however, I noted that the African form, Homo ergaster, characteristically shows postorbital constriction whereas Homo erectus does not.\n\nFossil 2 showed slight prognathism, a skull more nigh resembling modern Homo. However, the brow ridges present were more pronounced that in modern Homo. The small shovel-shaped teeth also are vocalism of an early Homo sapien because they ate more cooked vegetation and meat, their teeth were used less for the excoriation of hard, brittle vegetation. The fossil most closely displays the characteristics of Cro-Magnon, or Homo sapiens sapiens (Jurmain 281).\n\nSTATION 3:\nThe first mandibular bone is very robust and shows extreme molarization,...If you want to get a full essay, order it on our website:
