530 cc brain. The earliest australopithecine in the fossil record is Australopithecus afarensis. 2.3 - 1.2. mya. Evolved to see over the tall grass, to conserve energy, to free hands to use/make tools and carry food. it had a large brow ridge; it had a fairly flat face; it was found in central Africa. thick molar enamel; reduced canine dimorphism; sciatic notch. It first evolved in Arboreal Miocene Apes. When comparing the mean present the problematic concept of parallel evolution (Dean 1986: 249). Evolutionary records suggest that many different species of our modern genus, homo, and even some other hominids lived at the … Paranthropus boisei. Which of the following statements regarding the anatomy of the genus Ardipithecus is true? Australopithecus sediba was excavated by which of the following scientists and his team? Lived in open grasslands had a diet that more narrowly focused on sedges and grasses. It is intermediate between Hominins and Apes, The earliest australopithecine in the fossil record is Australopithecus Anamensis. Drag and drop each feature to the appropriate locomotor pattern. 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. 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 or homininians. However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. The genera Paranthropus, Kenyanthropus, and Homo, including modern humans, emerged in the genus Australopithecus. Australopithecus aethiopicus is the most primitive of the robust species. The first specimen OH 5 was found by Mary Leaky at Olduvai Gorge in 1959 after 28 years of searching. It is the most robust form of the robust australopithicenes, and is specialized towards heavy chewing.. it frees the hands to carry things; it allowed for efficient picking of fruit from trees; an erect posture helped maintain cooler body temperatures. The Paranthropus were lacking the transverse cranial crests in the … 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. The zygomatics were large and flared to allow for … A fossil skull has a flat face, large molars, and a prominent sagittal crest, suggesting it is ____. 4 mya) and Paranthropus robustus (1.8–1.5 mya) of South Africa do not differ markedly from those of A. afarensis.The locomotor skeleton of eastern African P. boisei (2.2–1.3 mya) is poorly known, but there is no reason to assume that it was different from other Paranthropus species. Walker & Leakey thought that the Homo species represented by KNM-ER 1470 was ancestral to H. erectus, whereas smaller-brained non-robust crania, such as KNM-ER 1813 (approx. C. less robust D. more robust Currently, it is believed that hominins first left Africa A. close to 2 million years ago B. due to a geologic catastrophe C. and went directly to North and South America D. all of these Which of the following characteristics helps to define a hominin? 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. One possible explanation for bipedalism is that it initially evolved as a feeding adaptation. Drag and drop the names in order from the earliest (oldest) species to the latest (youngest). humanorigins.si.edu/evidence/human-fossils/species/paranthropus-robustus They are characterised by robust craniodental anatomy, including gorilla-like cranial crests, which suggest strong muscles of mastication [Dawkins … PHYSICAL CHARACTERISTICS. narrow and elongated pelvis; short femur neck; parallel femurs; no longitudinal arch in foot. Postcranially, Paranthropus boisei is obviously bipedal. curved phalanges; a relatively small brain; marked facial prognathism. What is the function of the abductor muscles that run from the pelvis to the femur in bipedalism for upright walking? Australopithecines may not have walked exactly the same way that modern humans do. The thigh bone is set at a low angle to the shaft, with the shaft flattened from front to back, and there is a small hip joint surfact; all of these traits lead to better ballance. The gracile species appear earlier in the fossil record than the robust species, and the … Paranthropus vs. Australopithecus--P. aethiopicus, P. robustus, and P. boisei (the robust australopithecines) differ from A. anamensis, A. afarensis, and A. africanus (the gracile australopithecines) in a number of traits:--first deciduous molar distinguishes Paranthropus from all other hominid species It is clear that the main adaptive advantage to bipedalism was that it freed the hands for carrying things. Which of the following traits distinguish modern humans from other living hominoids? Sahelanthropus tchadensis; Orrorin tugenensis; Ardipithecus ramidus; Australopithecus anamensis, Place the following early hominins in order from the earliest (oldest) to the most recent (youngest), it first evolved in Miocene apes ( Miocene apes may have used an upright posture, using their feet to grasp branches and support their weight while they used their hands for balance and collecting food.). 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 robust species were consistently taller and heavier than the gracile ones. - large molars - flat face - sagittal crest - flared cheekbones - large lower jaw - small brain - small incisors - weak post cranial anatomy (not rugged/robust) It was originally named Zinjanthropus … The figure below displays 3 pelvises: those of a chimpanzee, Australopithecus afarensis, and a modern human (Homo sapiens). PARANTHROPUS ROBUSTUS . Paranthropus boisei or Australopithecus boisei was an early hominin, described as the largest of the Paranthropus genus (robust australopithecines). The earliest hominins were bipedal with large brains and small teeth. The face of Australopithecus robustus is which of the following? It is their skulls that set them apart; P. boisei had the most pronounced masticatory adaptations, so that relative to the other two species, they are termed “hyper-robust.” Along with the other robust forms, they shared a buttressed skull, face, and mandible; … Modern human body size and limb proportions first appeared with Homo erectus. a) Australopithecus anamensis : b) … Which of the following species are hominins? The earliest evidence of fundamentally bipedal hominids can be observed at the site of Laetoli in Tanzania. Orthognathic (flat) Paranthropus crassidens is now called Australopithecus robustus. Fossils from more than 100 individuals have been recovered in the last 55 years. It lived in Eastern Africa during the Pleistocene epoch from about 2.3 [discovered in Omo in Ethiopia] until about 1.2 million years ago. Australopithecus - named Australopithecus species include Australopithecus afarensis from East Africa, Australopithecus africanus from South Africa, Australopithecus garhi from Ethiopia, Australopithecus bahrelghazali from Chad (central Africa) and Australopithecus sediba from South Africa; Australopithecus fossils range from ca. a) afarensis and africanus : b) africanus : c) africanus and Orrorin: d) all of the above : 7. (a) C/P3 hone, (b) parabolic dental arch (c) thin enamel, (d) sectorial premolar. While the Olduvai material is attributed to Mary Leakey, it was her husb… In addition, P. robustus has better developed muscle markings, more prominent tori, and thicker buttressing structures than A. africanus . 2 - 1.5 mya. Which of the following is out of chronological order (listed from oldest to most recent)? Their faces, jaws, and cheek teeth were massive and truly unforgettable. Which of the following statements correctly describes the amount of genetic variation observed between human populations? Australopithecus (Paranthropus) boisei . Why were the species of Paranthropus robust? Which of the following statements regarding important things that are known about early hominins are correct? They were well-muscled species and roughly 1.3 m in height. The largest skull specimen found of Paranthropus boisei is dated to 1.4 million years old, discovered at Konso in Ethiopia. One of the key physiological differences between early humans (Homos) and Australopithecines was adult cranial capacity. In comparison to Humans, Paranthropus had ____. long femur neck; flattened and flared pelvis; longitudinal arch in foot; femurs angled inward, Sahelanthropus tchadensis; Ardipithecus ramidus; Australopithecus anamensis; Australopithecus afarensis; Australopithecus garhi. The robust species are often attributed to the genus Paranthropus (although some researchers retain them in Australopithecus) and generally have more massive jaws, crania, and molar and premolar (cheek) teeth than the gracile species, but all australopiths have more heavily built skulls than living apes. A. arboreal quadrupedalism B. long upper arms C. large brain size Background on Australopithecus and Paranthropus Species. Which of the following statements regarding important things that are known about early hominids are correct? Which of the following best describes the two competing hypotheses regarding the relationships among the robust australopiths? These hominid footprints are remarkably similar to modern humans and have been positively dated as 3.7 million years old. ), it is intermediate between hominins and apes. Australopithecus robustus and Australopithecus boisei. Most of the species of Paranthropus had a brain which was 40% in size of that of a modern man. Which of the following traits characterizes the early hominins? Paranthropus boisei is an extinct human ancestor that lived in the savannah environment of East Africa from 2.3 million until 1.2 million years ago. Past and current hominins differ in many ways. While the robust forms are somewhat larger than the gracile forms, they do not differ much postcranially. I use genus Australopithecus because it is thought to be descended from Au. Below is a map of Africa. Most of the species of Paranthropus had a brain which was 40% in size of that of a modern man. to keep the organism upright (prevent tipping at the hip) while walking. Chapter 13: The Bipedal Adaptation and Our Earliest Ancestors Reading Questions 1. 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. 5. toolkits for the manufacture of ochre pigment have been found … Along w/ Homo sapiens, hominins include all bipedal human ancestors since our split from the common ancestors w/ chimps. Which of the following early hominins is the oldest? 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 or homininians. Which of the following traits characterize robust Paranthropus species? The big chewing muscles attached to the sagittal crest are traits … The pelvis of Australopithecus afarensis is wider side to side and narrower front to back than that of a modern human, reflecting that australopithecines might not have locomoted (walked) exactly the way modern humans do. In addition, Paranthropus was the genus name assigned to the South African robust form, P. robustus, and questions remain as to whether the two species are related. 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 N/A. false (Australopithecus anamensis is the oldest of the australopithecines). 1. 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. the human lineage is derived from a small biped; males were taller and heavier than females. 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. The sagittal crest was higher and more posteriorly placed than in the two more derived robust species. Until recently, the footpr… Here is background on five species of early human ancestors. Which of the following is a feature of Australopithecus afarensis that is used to definitively classify this species as a hominin? Paranthropus. true (to be classified as a hominin, the species must be bipedal. aethiopicus has steadily increased. I prefer the separation of these species into the genus Australopithecus and Paranthropus based on the traits we will be looking at in today's lab, as well as … They are divided into two genus, although some sources (including your textbook) include them all in the genus Australopithecus. The zygomatics were large and flared to allow for … Sahelanthropus tchadensis; Australopithecus; Homo sapiens.

They lived between approximately 2.6 and 0.6 million years ago (mya) from the end of the Pliocene to the Middle Pleistocene. What can you conclude from this? They evolved after the robust species of australopithecines. 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. Australopithecus afarensis is one of the longest-lived and best-known early human species—paleoanthropologists have uncovered remains from more than 300 individuals! Which of the following traits characterize robust Paranthropus species?-large brain-flared cheekbones-sagittal crest-relatively rugged or robust post cranial anatomy -large molars-extremely enlarged front teeth (incisors and canines)-large lower jaw-flat face 4 mya) and Paranthropus robustus (1.8–1.5 mya) of South Africa do not differ markedly from those of A. afarensis.The locomotor skeleton of eastern African P. boisei (2.2–1.3 mya) is poorly known, but there is no reason to assume that it was different from other Paranthropus species. habitual bipedalism; large brains; parabolic dental arcade; material culture dependence. Refer to the casts provided by your instructor (or the pictures in the lab Appendix) to answer the following questions. 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. d) all of the above : 6. Despite this, they were still more robust than modern humans. Australopithecus is a member of the … Australopithecus robustus and A. boisei are also referred to as “robust” australopiths. 7. both a. and C. Distinctive traits of robust australopithecines include: large premolars and molars large temporalis muscles and a sagittal crest both a and b. size. Key physical features 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. Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei. 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. In human evolution: The fossil evidence. They were well-muscled species and roughly 1.3 m in height. 8. Select all that apply. A third physiological difference between Homo (all species) and Australopithecines was limb length-Australopithecines had much longer arms, although both genuses were bipedal. Which of the following statements regarding the evolution of bipedalism is true? Australopithecus Robustus. Which of the following are primitive or ancestral features of australopithecines relative to hominoids? I still remember the first time I saw them, and the species has always been for me one of the more interesting discoveries in paleoanthropology. Bouri, a 2.5-million-year-old site in central Ethiopia, yielded arm and leg bones that are contemporaneous with craniodental remains of A. garhi.The femur is elongated relative to the humerus, as in H. sapiens, but, unlike the human forearm, that of the fossil specimen…. The Paranthropus were lacking the transverse … Australopithecine Characteristics. The genus Paranthropus is characterized by robust craniodental anatomy, gorilla-like a sagittal cranial crest, broad grinding herbivorous teeth and strong muscles of mastication. Which of the following were australopithecine species? While the robust forms are somewhat larger than the gracile forms, they do not differ much postcranially. Different sizes of the temporalis muscle, which is involved in chewing through moving the jaw, indicate a different diet. Robert Broom discovered specimens of which of the following species at the site of Kromdraai in South Africa? These features allowed individuals to crush and grind hard foods such as nuts, seeds, roots, and tubers in the back of the jaw; however, P. robustus didn't just eat tough foods. Importance of bipedalism: Definition. Australopithecus aethiopicus. years ago. They are divided into two genus, although some sources (including your textbook) include them all in the genus Australopithecus. What conclusion can you make when comparing them? 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 6-10% of genetic variation occurs between major groupings of people. false (despite the gaps in the fossil record and the debates regarding interpretations of data, there are many important things that are known about early hominins).

Sahelanthropus tchadensis is an unusual hominin for which of the following reasons? Robust species like Paranthropus robustus had large teeth as well as a ridge on top of the skull, where strong chewing muscles attached. The species has a significantly larger cranial capacity than A. africanus, and is more similar to a modern brain. However, some still group P. boisei as a sister species of P. robustus and believe … Cranial capacity in this species suggests a slight rise in brain size (about 100 cc in 1 million years) independent of brain enlargement in the genus Homo. He was known for his robust cranial features that showed the signs of adaptation of the ecological niches. 4 to 2 Ma. A. aethiopicus existed between 2.6 and 2.3 million years ago. Determine which of the traits are similar to apes and which are similar to later hominins. Ardipithecus ramidus, Australopithecus anamensis, Australopithecus afarensis, Australopithecus garhi.

Below is a map of Africa. Researchers have suggested that this indicates a somewhat different style of bipedal locomotion.). Match each hominin species to its appropriate region in Africa: central, east, or south. The lack of consensus on one phylogeny of early hominins prevents us from understanding human evolution. paranthropus boisei. Found between 3.85 and 2.95 million years ago in Eastern Africa (Ethiopia, Kenya, Tanzania), this species survived for more than 900,000 years, which is over four times as long as our own species has been around. their jaws and teeth were adapted to heavy chewing.
