10. Robust Australopithecine species include. Bipedalism’s advantages over quadrupedalism include This question may be completed independently or as a group exercise. The name Paranthropus walkeri is under review and this species is often referred to as Paranthropus (or Australopithecus) aethiopicus. aethiopicus †P. garhi Formerly Australopithecus, now Paranthropus †P. 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. True or False: A C/P3 hone involves the upper canine sliding across the lower first premolar. Critical Thinking Questions. 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. 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 … 1 Evolution … 5. 4 to 1 mya. Refer to the casts provided by your instructor (or the pictures in the lab Appendix) to answer the following questions. 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. 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 genus Australopithecine includes hominins that lived about. Please answer the following about Selam:a. List all of the different species of Australopithecus and about when did they live? 9. What is significant about the anatomy of Lucy’s body? There is considerable disagreement, … 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. The best known australopithecines, represented by hundreds of fossils and dozens of individuals found mostly at Laetoli and Hadar is. 7. Au. Which of the following is evidence of robust australopithecines' adaptation to eating hard-shelled seeds and grasses? Aethiopicus. Afarensis. Key physical features. 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? 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. 1. 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. The general term australopith (or australopithecine) is used informally to refer to members of the genus Australopithecus. Species †A. (a) sagittal crest, (b) nuchal crest, (c) dished face, (d) small molar teeth. Why had the finding of Lucy been considered to be so significant when it was found in 1974 (up to recently)? b. (Gracile means "slender", and in paleoanthropology is used as an antonym to "robust".) robustus †P. africanus †A. Biological anthropologists disagree about the best way to classify the robust australopithecines. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelghazali and A. deyiremeda. anamensis †A. Au. bahrelghazali †A. Please answer the following about Lucy: a. Despite this, they were still more robust than modern humans. Which of these mystery australopithecines is a later, more robust … Name one fossil species that may have made this stone tool. afarensis ("Lucy") †A. garhi is the oldest possible species that may have used tools such as this.
