Which of the following traits distinguish modern humans from other living hominoids? Determine which of the traits are similar to apes and which are similar to later hominins. Which of these mystery australopithecines is a later, more robust form? One possible explanation for bipedalism is that it initially evolved as a feeding adaptation. Australopithecus aethiopicus is the most primitive of the robust species. Drag and drop each feature to the appropriate locomotor pattern. 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 Drag each hominin species to its appropriate region in Africa: central, east, or south. Different sizes of the temporalis muscle, which is involved in chewing through moving the jaw, indicate a different diet. Below is a list of features that characterize bipeds and quadrupeds among the hominoids. Australopithecus Robustus. Despite this, they were still more robust than modern humans. 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.

The name Paranthropus walkeri is under review and this species is often referred to as Paranthropus (or Australopithecus) aethiopicus. The robust species were consistently taller and heavier than the gracile ones. The largest skull specimen found of Paranthropus boisei is dated to 1.4 million years old, discovered at Konso in Ethiopia. I use genus Australopithecus because it is thought to be descended from Au.

The first specimen OH 5 was found by Mary Leaky at Olduvai Gorge in 1959 after 28 years of searching. 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. The earliest australopithecine in the fossil record is Australopithecus afarensis. the human lineage is derived from a small biped; males were taller and heavier than females. Why were the species of Paranthropus robust? Below is a map of Africa. 2 - 1.5 mya. The sagittal crest was higher and more posteriorly placed than in the two more derived robust species. Australopithecines may not have walked exactly the same way that modern humans do. True. 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. Characteristics of Bipedalism: ... S curved spine, bowl shaped pelivs, centrally angled femurs, robust heel. They are divided into two genus, although some sources (including your textbook) include them all in the genus Australopithecus. Which of the following early hominins is the oldest? The species appears to have flourished between 2.7 and 2.5 million years ago. 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; large molars and … 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; … The Australopithecus species, referred to as Australopithecines, had features that were both human-like and ape-like. 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. Sahelanthropus tchadensis; Australopithecus; Homo sapiens. Elements of Lucy’s anatomy that suggest she may have spent some time in the trees include (a) short legs, (b) broad pelvis, (c) long arms, (d) short, straight digits. I use genus Australopithecus because it is thought to be descended from Au. They lived between approximately 2.6 and 0.6 million years ago (mya) from the end of the Pliocene to the Middle Pleistocene. The sagittal crest was higher and more posteriorly placed than in the two more derived robust species. N/A. 2.3 - 1.2. mya. Which of the following areas of the hominin body changed w/ bipedalism? A. aethiopicus existed between 2.6 and 2.3 million years ago. true (to be classified as a hominin, the species must be bipedal. 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 … sagittal crest; large lower jaw; flat face; flared cheekbones; large molars. paranthropus boisei. 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 In contrast, remains older than six million years are widely regarded to be those of fossil apes.

Place the following species or genera in order from smallest cranial capacity to largest cranial capacity. false (Australopithecus anamensis is the oldest of the australopithecines). Paranthropus boisei is a species of australopithecine from the Early Pleistocene of East Africa about 2.3 to 1.34 or 1 million years ago. A fossil skull has a flat face, large molars, and a prominent sagittal crest, suggesting it is ____________________. 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. It is the most robust form of the robust australopithicenes, and is specialized towards heavy chewing.. A. arboreal quadrupedalism B. long upper arms C. large brain size Homo sapiens; Australopithecus afarensis; Sahelanthropus tchadensis. 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. Which of the following is an ancestral feature found in the early Kenyan hominin Orrorin tugenensis that is shared with chimpanzees? Background on Australopithecus and Paranthropus Species. 1. Here is background on five species of early human ancestors. Which of the following statements regarding the evolution of bipedalism is true? Which of the following species has a sagittal crest in males, postcanine hpermegadontia, and forwardly placed zygomatics? PHYSICAL CHARACTERISTICS. 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. This division is made on the basis of their … It is clear that the main adaptive advantage to bipedalism was that it freed the hands for carrying things. Ardipithecus ramidus, Australopithecus anamensis, Australopithecus afarensis, Australopithecus garhi. 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 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. Support for P. boisei being descended from Au. The genus Paranthropus is characterized by robust craniodental anatomy, gorilla-like a sagittal cranial crest, broad grinding herbivorous teeth and strong muscles of mastication. The genus Paranthropus is characterized by robust craniodental anatomy, gorilla-like a sagittal cranial crest, broad grinding herbivorous teeth and strong muscles of mastication. 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. The genera Paranthropus, Kenyanthropus, and Homo, including modern humans, emerged in the genus Australopithecus. 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. They were well-muscled species and roughly 1.3 m in height. In lab, you examine a skull whose foramen magnum is centrally positioned at the bottom. Endocranial volume, or brain cavity capacity, varies among hominoids, with larger brains connected to longer growth periods. 8. Paranthropus boisei is a robust australopithecine which had a gorilla-like skull and powerful chewing muscles. 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. The face of Australopithecus robustus is which of the following? Paranthropus boisei or Australopithecus boisei was an early hominin, described as the largest of the Paranthropus genus (robust australopithecines). habitual bipedalism; large brains; parabolic dental arcade; material culture dependence. 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. hich of the following statements regarding the anatomy of the genus Ardipithecus is true? A third physiological difference between Homo (all species) and Australopithecines was limb length-Australopithecines had much longer arms, although both genuses were bipedal. The zygomatics were large and flared to allow for … The Paranthropus were lacking the transverse cranial crests in the … Orthognathic (flat) Paranthropus crassidens is now called Australopithecus robustus. 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. 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. They are also referred to as the robust australopithecines. They were well-muscled species and roughly 1.3 m in height. Australopithecus robustus and A. boisei are also referred to as “robust” australopiths. In the first course that I took in physical anthropology, I was most fascinated by the Paranthropus boisei face from Olduvai Gorge (see Figures 18.1 and 18.5) and the Natron/Peninj mandible from the Peninj site near Lake Natron. Which australopithecine species was the very first ever discovered? Australopithecine Characteristics. Describe why the earliest members of the human lineage were basically bipedal apes. Which of the following traits distinguish modern humans from other living hominoids? curved phalanges; a relatively small brain; marked facial prognathism. The holotype specimen, OH 5, was discovered by palaeoanthropologist Mary Leakey in 1959, and described by her husband Louis a month later. The earliest hominins were bipedal with large brains and small teeth. Which of the following statements regarding important things that are known about early hominins are correct?
