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 … 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? 4 to 1 mya. Why had the finding of Lucy been considered to be so significant when it was found in 1974 (up to recently)? Robust Australopithecine species include. Which of the following is evidence of robust australopithecines' adaptation to eating hard-shelled seeds and grasses? This question may be completed independently or as a group exercise. 5. Despite this, they were still more robust than modern humans. b. 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. True or False: A C/P3 hone involves the upper canine sliding across the lower first premolar. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelghazali and A. deyiremeda. 1 Evolution … Please answer the following about Selam:a. 7. garhi Formerly Australopithecus, now Paranthropus †P. What is significant about the anatomy of Lucy’s body? Name one fossil species that may have made this stone tool. africanus †A. 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. There is considerable disagreement, … aethiopicus †P. The best known australopithecines, represented by hundreds of fossils and dozens of individuals found mostly at Laetoli and Hadar is. Bipedalism’s advantages over quadrupedalism include (a) sagittal crest, (b) nuchal crest, (c) dished face, (d) small molar teeth. Which of these mystery australopithecines is a later, more robust … Key physical features. anamensis †A. Which of the following traits does not represent the robust australopithecines? 10. Aethiopicus. garhi is the oldest possible species that may have used tools such as this. robustus †P. 1. Critical Thinking Questions. List all of the different species of Australopithecus and about when did they live? Au. Species †A. bahrelghazali †A. The general term australopith (or australopithecine) is used informally to refer to members of the genus Australopithecus. 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. 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. Au. 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 … The name Paranthropus walkeri is under review and this species is often referred to as Paranthropus (or Australopithecus) aethiopicus. 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. Biological anthropologists disagree about the best way to classify the robust australopithecines. Afarensis. afarensis ("Lucy") †A. Please answer the following about Lucy: a. Refer to the casts provided by your instructor (or the pictures in the lab Appendix) to answer the following questions. 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. 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.
