Australopithecus is a member of the subtribe Australopithecina, which also includes Ardipithecus and Praeanthropus, though the term "australopithecine" is sometimes used to refer only to members of Australopithecus. Anthony Gambino Amanda Christopher Biological Anthropology 11/1/17 LAB 9 CHAPTER 15: exercises 1-6 and critical thinking questions 1-5 Exercise 1 Work in a small group or alone to complete this exercise. (Gracile means "slender", and in paleoanthropology is used as an antonym to "robust".) The name Paranthropus walkeri is under review and this species is often referred to as Paranthropus (or Australopithecus) aethiopicus. Bipedalism’s advantages over quadrupedalism include Biological anthropologists disagree about the best way to classify the robust australopithecines. Name one fossil species that may have made this stone tool. Please answer the following about Lucy: a. Please answer the following about Selam:a. Australopithecus ôstrā˝lōpĭth´əkəs, –pəthē´kəs [], an extinct hominin genus found in Africa between about 4 and 1 million years ago.At least seven species of australopithecines are now generally recognized, including Australopithecus afarensis, A. africanus, A. bahrelghazali, A. anamensis, A. boisei, A. robustus, and A. aethiopicus. 9. 1 Evolution … Australopithecus afarensis and africanus, and the other species above, are known as gracile australopithecines, because of their relatively lighter build, especially in the skull and teeth. 4 to 1 mya. Australopithecines include the genus Paranthropus (2.3–1.2 mya), which comprises three species of australopiths—collectively called the “robusts” because of their very large cheek teeth set in massive jaws. Critical Thinking Questions. 7. aethiopicus †P. garhi is the oldest possible species that may have used tools such as this. 5. 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.A large … Au. Au. Which of the following is evidence of robust australopithecines' adaptation to eating hard-shelled seeds and grasses? The genus Australopithecine includes hominins that lived about. b. 1. Afarensis. the presence of very large molars and a sagittal crest on the top of the skull Which of the following is not discussed in this chapter as a probable cause of the anatomical variety found in the australopithecine fossils? Which of these mystery australopithecines is a later, more robust … The general term australopith (or australopithecine) is used informally to refer to members of the genus Australopithecus. Refer to the casts provided by your instructor (or the pictures in the lab Appendix) to answer the following questions. afarensis ("Lucy") †A. africanus †A. There is considerable disagreement, … (a) sagittal crest, (b) nuchal crest, (c) dished face, (d) small molar teeth. boisei The gracile australopithecines (members of the genus Australopithecus) (Latin australis "of the south", Greek pithekos "ape") are a group of extinct hominids that are closely related to humans. bahrelghazali †A. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelghazali and A. deyiremeda. 10. True or False: A C/P3 hone involves the upper canine sliding across the lower first premolar. garhi Formerly Australopithecus, now Paranthropus †P. robustus †P. What is significant about the anatomy of Lucy’s body? This question may be completed independently or as a group exercise. Australopithecina or Hominina is a subtribe in the tribe Hominini.The members of the subtribe are generally Australopithecus (cladistically including the genera Homo, Paranthropus, and Kenyanthropus), and it typically includes the earlier Ardipithecus, Orrorin, Sahelanthropus, and Graecopithecus.All these related species are now sometimes collectively termed australopiths … List all of the different species of Australopithecus and about when did they live? Why had the finding of Lucy been considered to be so significant when it was found in 1974 (up to recently)? Which of the following traits does not represent the robust australopithecines? Aethiopicus. All three species share similar physical characteristics - a relatively small body and a ‘robust’ or strongly built skull including large lower jaws with extremely large molar teeth. The best known australopithecines, represented by hundreds of fossils and dozens of individuals found mostly at Laetoli and Hadar is. anamensis †A.
