Short and robust, height not more than 4 ft 3 in: Taller and more slenderly built than all other Homo species, average height was 5 ft 10 in: Facial Features: Protruding face with prominent cheekbones: Relatively flatter face with less prominent cheekbones and large brow-ridges: Limbs: Disproportionately long arms, but shorter legs The species appears to have flourished between 2.7 and 2.5 million years ago. d) all of the above : 6. Most of the species of Paranthropus had a brain which was 40% in size of that of a modern man. A fossil skull has a flat face, large molars, and a prominent sagittal crest, suggesting it is ____________________. Which of the following traits characterize robust Paranthropus species? Robert Broom discovered specimens of which of the following species at the site of Kromdraai in South Africa? Which of the following were australopithecine species? What can you conclude from this? Mystery primate A is the later, more robust primate. Their faces, jaws, and cheek teeth were massive and truly unforgettable. Paranthropus robustus. It is intermediate between Hominins and Apes, The earliest australopithecine in the fossil record is Australopithecus Anamensis. Below is a map of Africa. Evolutionary records suggest that many different species of our modern genus, homo, and even some other hominids lived at the … Paranthropus robustus is a species of robust australopithecine from the Early and possibly Middle Pleistocene of the Cradle of Humankind, South Africa, about 2 to 1 or 0.6 million years ago.It has been identified in Kromdraai, Swartkrans, Sterkfontein, Gondolin, Cooper's, and Drimolen Caves. One possible explanation for bipedalism is that it initially evolved as a feeding adaptation. c) They generally were slender and delicate boned. Paranthropus. Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei. Match the hominin genus to the correct suite of characteristics. The first undisputed evidence of the genus Homo—the genus that includes modern human beings—appears as early as 2.8 mya, and some of the characteristics of Homo resemble those of earlier species of Australopithecus; however, considerable debate surrounds the identity of the earliest species of Homo. In contrast, remains older than six million years are widely regarded to be those of fossil apes. I use genus Australopithecus because it is thought to be descended from Au. (a) A. afarensis, (b) A. africanus, (c) A. robustus, (d) A. boisei. Australopithecus aethiopicus is the most primitive of the robust species. Which of the following is a feature of Australopithecus afarensis that is used to definitively classify this species as a hominin? PHYSICAL CHARACTERISTICS. Australopithecus robustus and A. boisei are also referred to as “robust” australopiths. Which of the following traits does not represent the robust australopithecines? When comparing the mean present the problematic concept of parallel evolution (Dean 1986: 249). 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. On average, early humans had brains that were about 35 percent larger than Australopithecus africanus, who is widely considered to be one of two possible immediate ancestors of early humans the other is Australopithecus garhi. In addition to a well-developed skull crest for the attachment of the temporalis (or temporal muscle, which is used in chewing), other specializations for strong chewing include huge cheek teeth, massive jaws, and powerfully built cheekbones that project forward. Generally, the australopithecines can be divided into two broad categories based on their dental characteristics: the ‘gracile’ (Australopithecus) and robust (Paranthropus) australoptihecines. Which of the following traits distinguish modern humans from other living hominoids? The genus Paranthropus is characterized by robust craniodental anatomy, gorilla-like a sagittal cranial crest, broad grinding herbivorous teeth and strong muscles of mastication. Australopithecus is a member of the … The largest skull specimen found of Paranthropus boisei is dated to 1.4 million years old, discovered at Konso in Ethiopia. their jaws and teeth were adapted to heavy chewing. Australopithecus aethiopicus. Australopithecine Characteristics. Australopithecus (Paranthropus) robustus . While the robust forms are somewhat larger than the gracile forms, they do not differ much postcranially. He was known for his robust cranial features that showed the signs of adaptation of the ecological niches. Below is a list of traits found in Ardipithecus ramidus. long femur neck; flattened and flared pelvis; longitudinal arch in foot; femurs angled inward, Sahelanthropus tchadensis; Ardipithecus ramidus; Australopithecus anamensis; Australopithecus afarensis; Australopithecus garhi. Describe why the earliest members of the human lineage were basically bipedal apes. The pelvis is more human than chimpanzee: it … Evolved to see over the tall grass, to conserve energy, to free hands to use/make tools and carry food. The zygomatics were large and flared to allow for … Specifically, P. boisei fossils have been found at sites in Tanzania (Olduvai … size. Which of the following areas of the hominin body changed w/ bipedalism? Robust australopithecines (Paranthropus) had larger cheek teeth than gracile australopiths, possibly because robust australopithecines had more tough, fibrous plant material in their diets, whereas gracile australopiths ate more hard and brittle foods. Their muscles of mastication were incredibly strong, as evidenced by the sagittal crest running down the midline of their skull where the temporalis muscle originated. Paranthropus boisei. The sagittal crest was higher and more posteriorly placed than in the two more derived robust species. Sahelanthropus tchadensis is an unusual hominin for which of the following reasons? Australopithecines may not have walked exactly the same way that modern humans do. While the robust forms are somewhat larger than the gracile forms, they do not differ much postcranially. This species had even larger cheek teeth than P. robustus,a flatter, bigger-brained skull than P. aethiopicus, and the thickest dental enamel of any known early human. These hominid footprints are remarkably similar to modern humans and have been positively dated as 3.7 million years old. Which of the following statements regarding important things that are known about early hominins are correct? Background on Australopithecus and Paranthropus Species. This species is known from one major specimen, the Black Skull discovered by Alan Walker, and a few other minor specimens which may belong to the same species. habitual bipedalism; large brains; parabolic dental arcade; material culture dependence. Australopithecus boisei and A. robustus are sister taxa that evolved from A. aethiopicus OR, 2. the South African and East African taxa are separate lineages correct Which of the following statements regarding important things that are known about early hominids are correct? Which of the following traits characterizes the early hominins? They are divided into two genus, although some sources (including your textbook) include them all in the genus Australopithecus. 2.3 - 1.2. mya. Australopithecus afarensis is one of the longest-lived and best-known early human species—paleoanthropologists have uncovered remains from more than 300 individuals! Australopithecus (/ ˌ ɒ s t r ə l ə ˈ p ɪ θ ɪ k ə s /, OS-trə-lə-PITH-i-kəs; from Latin australis 'southern', and Greek πίθηκος (pithekos) 'ape'; singular: australopith) is a (supra-)genus of hominins that existed in Africa from around 4.2 million years ago. 2 - 1.5 mya. This species is grouped with the Australopitecine genus, Paranthropus boisei because of the robusticity of the skull and the prominent characteristics. years ago. In addition, P. robustus has better developed muscle markings, more prominent tori, and thicker buttressing structures than A. africanus . The search string "treehouses" appears in the following group names or in other names (synonyms, vernacular names) applied to these groups: Search Again Group Name Most of the species of Paranthropus had a brain which was 40% in size of that of a modern man. In human evolution: The fossil evidence …it was different from other Paranthropus species. PHYSICAL CHARACTERISTICS. PHYSICAL CHARACTERISTICS. Fossils from more than 100 individuals have been recovered in the last 55 years. The earliest australopithecine in the fossil record is Australopithecus afarensis. This species was found well preserved with a complete cranium but lacking dentition. The gracile species appear earlier in the fossil record than the robust species, and the … humanorigins.si.edu/evidence/human-fossils/species/paranthropus-robustus Which of the following are primitive or ancestral features of australopithecines relative to hominoids? 1. The zygomatics were large and flared to allow for … aethiopicus has steadily increased. In human evolution: The fossil evidence. it frees the hands to carry things; it allowed for efficient picking of fruit from trees; an erect posture helped maintain cooler body temperatures. 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 … Paranthropus: Species: Paranthropus robustus: Time Period: 2 to 1.2 million years ago: Characteristics: Bipedal: Fossil Evidence: Skull & Teeth Fossils, Kromdraai, South Africa: Bradshaw Foundation. The face of Australopithecus robustus is which of the following? sagittal crest; large lower jaw; flat face; flared cheekbones; large molars. Orthognathic (flat) Paranthropus crassidens is now called Australopithecus robustus. They are divided into two genus, although some sources (including your textbook) include them all in the genus Australopithecus. One of the key physiological differences between early humans (Homos) and Australopithecines was adult cranial capacity. Read More 510 cc brain. The earliest evidence of fundamentally bipedal hominids can be observed at the site of Laetoli in Tanzania. However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. true (to be classified as a hominin, the species must be bipedal. It was originally named Zinjanthropus … curved phalanges; a relatively small brain; marked facial prognathism. Their muscles of mastication were incredibly strong, as evidenced by the sagittal crest running down the midline of their skull where the temporalis muscle originated. Chapter 13: The Bipedal Adaptation and Our Earliest Ancestors Reading Questions 1. (a) sagittal crest, (b) nuchal crest, … (a) C/P3 hone, (b) parabolic dental arch (c) thin enamel, (d) sectorial premolar. ), it is intermediate between hominins and apes. Derived robust characteristics are buttressing of the skull, face, and mandible. Importance of bipedalism: Definition. to keep the organism upright (prevent tipping at the hip) while walking. A strong sagittal crest on the midline of the top of the skull anchored the temporalis muscles (large chewing muscles) from the top and side of the braincase to the lower jaw, and thus moved the massive jaw up and down. Which of the following are primitive or ancestral features of australopithecines relative to hominoids? The Paranthropus were lacking the transverse cranial crests in the … The figure below displays 3 pelvises: those of a chimpanzee, Australopithecus afarensis, and a modern human (Homo sapiens). Which of the following is out of chronological order (listed from oldest to most recent)? The first specimen OH 5 was found by Mary Leaky at Olduvai Gorge in 1959 after 28 years of searching. At first, several discoverers of the various Australopithecus fossils named four to five different genera, but now the consensus of scientific opinion recognizes one genus Australopithecus and two species, one gracile form represented by Australopithecus africanus and other robust form represented by Australopithecus robustus, originally called Paranthropus. Paranthropus boisei, arguably the best known of the “robust australopithecines,” (the species included in the genus Paranthropus—Paranthropus aethiopicus, Paranthropus robustus, and Paranthropus boisei) is known from East African sites dating between 2.4 and 1.4 million years ago.
