Australopithecus africanus is an extinct species of australopithecine which lived from 3.67 to 2 million years ago in the Middle Pliocene to Early Pleistocene of South Africa. The earliest known biped is: A. Acrobatus bipedus B. Homo erectus C. Homo habilis D. Robust Australopithecines E. Ardipithecus ramidus or earlier 3. boisei 4. Kromdraai is a limestone cave that has occasionally had openings to the surface. not as important), the test is said to be robust. Which of these mystery australopithecines is a later, more robust form? 4.3 million years C. 23 million years D. 2.4 million years ANS: B TYPE: Factual PG: 81 24. In several variations of Australopithecine there is a considerable degree of sexual dimorphism, meaning that males are larger than females. B) The mean of the residuals is equal to the variance at all combinations of levels of the independent variables. ANS: B PTS: 2 14. Answer Save. Australopithecine definition is - any of various extinct hominids (genera Australopithecus and Paranthropus) that existed two to four million years ago in southern and eastern Africa and include gracile and robust forms exhibiting bipedal locomotion, near-human dentition, and relatively small brains. Although Robinson (1972) and Napier (1967) have suggested that australopithecine forms may not D) australopithecines certainly do form a distinct tribe. Which of the following is not an advantage of bipedalism among humans? I determined this because mystery australopithecine “B” has a thinner face and jaw. Tanzania. The term australopithecine came from a former classification as members of a distinct subfamily, the Australopithecinae. a collection of robust australopithecine fossils. Multiple-choice questions: A. The fossil was found at a lime quarry at Taung, southwest of Johannesburg, and was of an immature apelike individual. Homo Habilis A. africanus A. afarensis A. boisei Ardipithecus ramidus. A. Australopithecus Robustus. → Paranthropus robustus is an example of a robust australopithecine; they had very large megadont cheek teeth with thick enamel and focused their chewing in the back of the jaw.Large zygomatic arches (cheek bones) allowed the passage of large chewing muscles to the jaw and gave P. robustus individuals their characteristically wide, dish-shaped face. "Later fossil finds indicated that Ramapithecus was more closely related to the orang-utan, and new biochemical evidence indicated that the last common ancestor of hominids and apes occurred between 5 and 10 million years ago, and probably in the lower end of that range (Lewin 1987). B. Australopithecus Aethiopicus C. Australopithecus Africanus. 2. Kenya. Australopithecus afarensis is an extinct species of australopithecine which lived from about 3.9–2.9 million years ago (mya) in the Pliocene of East Africa.The first fossils were discovered in the 1930s, but major fossil finds would not take place until the 1970s. 1) Which of the following is not an assumption of the multiple regression model? E. all of the above 2. Which of the following is not a location where australopithecine fossils have been found? 23. Which of the following is not considered a robust australopithecine? Which of the following would not be part of an Oldowan toolkit? 23. The power of a test is its ability to detect a significant difference if there is a true difference. Homo habilis ("handy man") is a species of archaic human from the Early Pleistocene of East and South Africa about 2.3–1.65 million years ago (mya). afarensis, Au. The fossil individual nicknamed Lucy was B. a habitual biped (not a typical robust australopithecine, unusually tall, or alive around 2 mya). D. Australopithecus Boisei. E) some prominent paleoanthropologists are not convinced and have threatened to withdraw from the American Anthropological Association. The Sagittal Crest Functions To A. Anchor Chewing Muscles. ... Why is Hyannis, Massachusetts considered as a village, even though it lies within the boundaries in the Town of Barnstable (now a city)? The robust forms were slightly taller and weighed between 80 and 140 pounds. The following year, ... Paranthropus boisei is a robust australopithecine which had a gorilla-like skull and powerful chewing muscles. Chimpanzee subspecies and 'robust' australopithecine holotypes, in the context of comments by Darwin December 2009 South African Journal of Science 105(11-12):463-464 Two East African australopithecines are any two of the following: Australopithecus anamensis, Au. aethiopicus, Au. Gibraltar. It consists of 40 multiple choice questions (each worth 1 point) and two essay questions. Describe two anatomical traits you used to make this determination. Australopithecus anamensis. Raymond Dart discovered the first australopithecine in November, 1924. 2. Non-australopithecine members of the human lineage include Sahelanthropus tchadensis (7–6 mya), Orrorin tugenensis (6 mya), Ardipithecus kadabba (5.8–5.2 mya), and Ar. The fossil existed of the face, part of the cranium, the complete lower jaw and a brain endocast, formed when sand inside the skull hardened to rock, recording the shape of the brain. all of the above. A) The residuals have a constant variance for all combinations of values for the independent variables.
