What does the Regional Continuity Model of modern Homo sapiens origins propose? Her neurocranium is small and primitive, while she possesses more spatulate canines than other apes. A cast of the original skeleton in its reconstructed form is displayed at the Cleveland Museum of Natural History. The first reconstruction had little iliac flare and virtually no anterior wrap, creating an ilium that greatly resembled that of an ape. They noticed part of a femur (thigh bone) a few feet (about one meter) away. concluded that this morphology arose "independently in gorillas and hominins", and that A. afarensis is "too derived to occupy a position as a common ancestor of both the Homo and robust australopith clades". They found the well-preserved remains of a three-year-old girl of the species Australopithecus afarensis, which includes the fossil skeleton known as Lucy, in the Dikika area of Ethiopia. Answer to The fossil skeleton known as `` Lucy '' belongs to the species a . Lucy was exhibited at the Discovery Times Square Exposition in New York City from June until October 2009. The Houston Museum made arrangements for exhibiting at ten other museums, including the Pacific Science Center in Seattle. Johanson assessed it as female based on the one complete pelvic bone and sacrum, which indicated the width of the pelvic opening. The fossil known as Lucy is one of the oldest and best-preserved skeletons of a hominid (two-footed, humanlike primate). Her remains were found in Hadar, Ethiopia, in 1974 by American anthropologist Donald Johanson and his student, Tom Gray. The fossil belongs to an ancient hominin known as Australopithecus anamensis, which is believed to be the direct ancestor of Australopithecus afarensis or the famous “Lucy” species—the very ancient ancestor of modern humans. It is best known from the sites of Hadar, Ethiopia (‘Lucy’, AL 288-1 and the 'First Family', AL 333); Dikika, Ethiopia (Dikika ‘child’ skeleton); and Laetoli (fossils of this species plus the … Remarkably, unlike most hominid(modern and extinct Great Apes) fossils, up … Which of the following would be best suited to the carbon-14 dating technique? certain organic materials less than 75,000 years old. Upper Pleistocene premodern Homo sapiens that have their evolutionary roots in Europe are called ____. [33] At the American Museum of Natural History in New York City a diorama presents Australopithecus afarensis and other human predecessors, showing each species and its habitat and explaining the behaviors and capabilities assigned to each. Selam is the fossilized skull and other skeletal remains of a three-year-old Australopithecus afarensis female hominin, whose bones were first found in Dikika, Ethiopia in 2000 and recovered over the following years. On a hunch, Johanson decided to look at the bottom of a small gully that had been checked at least twice before by other workers. The skull of Australopithecus prometheus is part of the fossil skeleton known as Little Foot, which has most recently been dated to about 3.7 million years ago. Thus far, there is agreement that all hominids found outside Africa are members of which genus? Each section below discusses aspects of Lucy's anatomy that help us determine her mode of locomotion. It is called Dinkinesh in Ethiopia according to the Amharic language. Solved Lucy was an australopithecine fossil. Her acetabulum, however, was small and primitive. The genetic analysis of Neandertal fossils indicates they were ____. The fossil skeleton known as "Lucy" belongs to which species? However, this reconstruction proved to be faulty, as the superior pubic rami would not have been able to connect were the right ilium identical to the left. For these reasons, the Smithsonian Institution and Cleveland Museum of Natural History and other museums declined to host the exhibits. afarensis . Lucy a 3.2-million-year-old skeleton discovered in 1974 belongs to Australopithecus afarensis, a species which scientists think was an early direct ancestor of modern humans. The only visible damage is a single carnivore tooth mark on the top of her left pubic bone, believed to have occurred at or around the time of death, but which is not necessarily related to her death. d . e . The fossil skeleton known as "Lucy" belongs to which species? [21], Initial attempts were made in 1974 by Maurice Taieb and James Aronson in Aronson's laboratory at Case Western Reserve University to estimate the age of the fossils using the potassium-argon radiometric dating method. [9], In November 1971, near the end of the first field season, Johanson noticed a fossil of the upper end of a shinbone, which had been sliced slightly at the front. More than 40 years later, Australopithecus afarensis is one of the best-represented species in the hominin fossil record. The argument between "lumpers" and "splitters" is concerned with: The number of species in a set of fossil remains. The skeleton presents a small skull akin to that of non-hominin apes, plus evidence of a walking-gait that was bipedal and upright, akin to that of humans (and other hominins); this combination supports the view of human evolution that bipedalism preceded increase in brain size. When it was resumed thirteen years later in 1990, the more precise argon-argon technology had been updated by Derek York at the University of Toronto. Types of Upper Paleolithic art include which of the following? A nearly-complete skull of an ancient Australopithecus anamensis fossil was recently discovered in Ethiopia. It is used to increase the force and distance of a spear throw. about three times as different from modern Homo sapiens samples as they are from each other. Where have Neandertal skeletal remains NOT been found? Question: D Question 1 0.12 Pts Time El Attempt O Minu Dating 3.2 Nya, The Fossil Skeleton Known As "Lucy Belongs To Which Species Of Australopithecine? Australopithecus afarensis seems to have had the same conical rib-cage found in today's non-human great apes (like the chimpanzee and gorilla), which allows room for a large stomach and the longer intestine needed for digesting voluminous plant matter. Excavation, preservation, and analysis of the specimen Ardi was very difficult and time-consuming; work was begun in 1992, with the results not fully published until October 2009. The question of whether continuous local evolution produced anatomically modern groups directly from some regions of Eurasia ____. Lucy was found by Donald Johanson and Tom Gray on November 24, 1974, at the site of Hadar in Ethiopia. A plaster replica is publicly displayed there instead of the original skeleton. The heavier musculature of the jaws—those muscles operating the intensive masticatory process for chewing plant material—similarly would also limit development of the braincase. The most iconic fossil of A. afarensis is probably the partial skeleton known as Lucy, which was for a long time viewed as the oldest known human ancestor. Solved The famous fossil Lucy is which type of Australopithecus? The cranial capacity was about 375 to 500 cc. The greater trochanter, however, is clearly a derived trait, being short and human-like—even though, unlike in humans, it is situated higher than the femoral head. The find, from 3.8 million years ago, reveals the face for a presumed ancestor of the species famously represented by Lucy, the celebrated Ethiopia n partial skeleton found in 1974. A six-year exhibition tour of the United States was undertaken during 2007–13; it was titled Lucy's Legacy: The Hidden Treasures of Ethiopia and it featured the actual Lucy fossil reconstruction and over 100 artifacts from prehistoric times to the present. The French Neandertal site of St. Césaire dates to ____ years ago. [19], With the permission of the government of Ethiopia, Johanson brought all the skeletal fragments to the Cleveland Museum of Natural History in Ohio, where they were stabilized and reconstructed by anthropologist Owen Lovejoy. The lower end of a femur was found near it, and when he fitted them together, the angle of the knee joint clearly showed that this fossil, reference AL 129-1, was an upright walking hominin. During evolution of the human lineage these muscles seem to have weakened with the loss of the myosin gene MYH16, a two base-pair deletion that occurred about 2.4 million years ago. They had taken a Land Rover out that day to map in another locality. Ethiopia celebrated the return of Lucy in May 2013. A cast of the skeleton as well as a corpus reconstruction of Lucy is displayed at The Field Museum in Chicago. [4][5] A 2016 study proposes that Australopithecus afarensis was also to a large extent tree-dwelling, though the extent of this is debated.[6][7]. [26] Rak et al. By 1992 Aronson and Robert Walter had found two suitable samples of volcanic ash—the older layer of ash was about 18 m below the fossil and the younger layer was only one meter below, closely marking the age of deposition of the specimen. is sometimes used to refer to African Homo erectus specimens, The Upper Paleolithic culture period began in Western Europe about ____ years ago. is a 24,500 year-old specimen from Portugal that may show evidence of mixing between Neandertals and early modern humans. There are indications of degenerative disease to her vertebrae that do not necessarily indicate old age. You will hypothesize the evolutionary relationship between Lucy’s species and modern humans. Separate origins in Africa and Australia with migrations from both these areas to displace all other populations. The oldest possible hominid found to date has been given which genus name? Then, on the morning of 24 November 1974, near the Awash River, Johanson abandoned a plan to update his field notes and joined graduate student Tom Gray to search Locality 162 for bone fossils. Large brains were NOT required to migrate out of Africa. Her pubic arch was over 90 degrees and derived; that is, similar to modern human females. [30][31] Donald Johanson and Tim White disagreed with the suggestions.[32]. Johanson suggested taking an alternate route back to the Land Rover, through a nearby gully. July 30, 2017 Anthropology. Fully 60% of the blood supply of non-human apes is used in the digestion process, greatly impeding the development of brain function (which is limited thereby to using about 10% of the circulation). The fossil skeleton known as "Lucy" belongs to which species? Mousterian and Middle Paleolithic are both correct terms. "Lucy" acquired her name from the song "Lucy in the Sky with Diamonds" by the Beatles, which was played loudly and repeatedly in the expedition camp all evening after the excavation team's first day of work on the recovery site. It is called Australopithecus afarensis. What is the Neandertal site in Croatia that has produced nonhuman faunal remains, and some hominid remains? are more robust than those from Mungo and are from Australia. The Middle Pleistocene began about ____ years ago. They marked the spot and returned to camp, excited at finding so many pieces apparently from one individual hominin. The discovery of Lucy contains hundreds of bone fossils, which make up 40 percent of her skeletal body. [8] In September 2008, between the exhibits in Houston and Seattle, the skeletal assembly was taken to the University of Texas at Austin for 10 days to perform high-resolution CT scans of the fossils.[36]. The fossil skeleton known as Lucy belongs to which species? The creature had a small brain like a chimpanzee, but the pelvis and leg bones were almost identical in function to those of modern humans, showing with certainty that Lucy's species were hominins that had stood upright and had walked erect. Where have the fossil remains of forty or more Homo erectus individuals and thousands of artifacts been found? What is the average cranial capacity of H. erectus? An exceptionally petite female her estimated height was 3.5 feet (1.1 meters) Lucy's small frame has been interpreted as not being totally adapted for human-like, upright walking. The robust australopithecines lived roughly _____ million years ago . This ancestral species is the oldest known member of Australopithecus, a grouping of creatures that preceded our own branch of the family tree, called Homo. Johanson recovered Lucy's left innominate bone and sacrum. The length ratio of her humerus (arm) to femur (thigh) is 84.6%, which compares to 71.8% for modern humans, and 97.8% for common chimpanzees, indicating that either the arms of A. afarensis were beginning to shorten, the legs were beginning to lengthen, or both were occurring simultaneously. [17], Over the next three weeks the team found several hundred pieces or fragments of bone with no duplication, confirming their original speculation that the pieces were from a single individual; ultimately, it was determined that an amazing 40 percent of a hominin skeleton was recovered at the site. Lucy became famous worldwide, and the story of her discovery and reconstruction was published in a book by Johanson. [8][35], The fossil's discoverer Don Johanson stated his concern for the possibility of damage, but did not oppose touring and exhibiting Lucy, as he felt it would raise awareness of human-origins studies. https://quizlet.com › 200090287 › anth-2-unit-3-exam-flash-cards Who made the first discovery of what we now call Homo erectus fossil remains. Some nine years later, and now assembled altogether, she was returned to Ethiopia. Lucy is the common name of AL 288-1, several hundred pieces of fossilized bone representing 40 percent of the skeleton of a female of the hominin species Australopithecus afarensis. Which of the following sites, dated to approximately 300,000 years ago, has yielded a sample representing about twenty-eight premodern Homo sapiens individuals? [1][2][3], The Lucy specimen is an early australopithecine and is dated to about 3.2 million years ago. [34] A portion of the proceeds from the tour was designated to modernizing Ethiopia's museums. Near it lay a fragment from the back of a small skull. B. the fossil skeleton known as “Lucy” belongs to this species C. is found in southern and eastern Africa D. all of these Compared to australopithecines and modern humans, what were Homo erectus limb bones? What do the fossil remains from Dmanisi indicate? The various species lived 4.4 million to 1.4 million years ago, during the Pliocene and Pleistocene epochs. The oldest Homo erectus remains from East and West Lake Turkana are ____ years old. Lucy also had a lordose curve, or lumbar curve, another indicator of habitual bipedalism. The Lucy skeleton is preserved at the National Museum of Ethiopia in Addis Ababa. aethiopicus . Lucy was discovered in 1974 in Africa, at Hadar, a site in the Awash Valley of the Afar Triangle in Ethiopia, by paleoanthropologist Donald Johanson of the Cleveland Museum of Natural History. 1/2. Taieb formed the International Afar Research Expedition (IARE) and invited three prominent international scientists to conduct research expeditions into the region. [10][11], The team returned for the second field season the following year and found hominin jaws. [24] She apparently had physiological flat feet, not to be confused with pes planus or any pathology, even though other afarensis individuals appear to have had arched feet.[25]. The fossil belongs to an ancient hominin known as Australopithecus anamensis, which is believed to be the direct ancestor of Australopithecus afarensis or the famous “Lucy” species. Which of the following premodern Homo sapiens crania shows possible evidence of cannibalism in the form of cut marks? There was controversy in advance of the tour over concerns about the fragility of the specimens, with various experts including paleoanthropologist Owen Lovejoy and anthropologist and conservationist Richard Leakey publicly stating their opposition. The hypothesis that all modern humans descended from an African lineage ____. There was discussion of the risks of damage to the unique fossils, and other museums preferred to display casts of the fossil assembly. [38] She was also exhibited in Mexico at the Mexico Museum of Anthropology until its return to Ethiopia in May 2013. What was Neandertal subsistence based on? [27], Work at the American Museum of Natural History uncovered a possible Theropithecus vertebral fragment that was found mixed in with Lucy's vertebrae, but confirmed the remainder belonged to her. Its story began to take shape in late November 1974 in Ethiopia, with the discovery of the skeleton of a small female, nicknamed Lucy. 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. habilis . 2.5-1 Million years ago. Despite being uncovered 40 years ago, Lucy is still being studied to learn more about our ancestors. Premodern humans appeared in Europe, Asia, and Africa and allevolved simultaneously into modern humans while experienceing gene flow between populations. This relatively complete female skeleton, dated to 3.2 million years old, is the most famous individual from this species. This relative dating methods is used to cross-correlate dates from South African hominid sites. b . [29], In 2016 researchers at the University of Texas at Austin suggested that Lucy died after falling from a tall tree. At first view nothing was immediately visible, but as they turned to leave a fossil caught Johanson's eye; an arm bone fragment was lying on the slope. Lucy the Australopithecus afarensis, a fossilised skeleton found 41 years ago, is being commemorated by the Google Doodle.But how did she get there? Beginning in 2007, the fossil assembly and associated artifacts were exhibited publicly in an extended six-year tour of the United States; the exhibition was called Lucy's Legacy: The Hidden Treasures of Ethiopia. His subsequent expedition led to the discovery of Lucy, a 40 percent complete skeleton of a new species of hominid, now known as Australopithecus afarensis. is supported by both mtDNA and Y chromosome evidence. Lucy was discovered in 1974 in Africa, at Hadar, a site in the Awash Valley of the Afar Triangle in Ethiopia, by paleoanthropologist Donald Johanson of the Cleveland Museum of Natural History. [22], One of the most striking characteristics of the Lucy skeleton is a valgus knee,[23] which indicates that she normally moved by walking upright. Lucy was of the species Australopithecus afarensis. africanus . A later reconstruction by Tim White showed a broad iliac flare and a definite anterior wrap, indicating that Lucy had an unusually broad inner acetabular distance and unusually long superior pubic rami. [citation needed], A study of the mandible across a number of specimens of A. afarensis indicated that Lucy's jaw was rather unlike other hominins, having a more gorilla-like appearance. This fossil was later dated at more than three million years old—much older than other hominin fossils known at the time. (The Lucy skeleton occurs in the part of the Hadar sequence that accumulated with the fastest rate of deposition, which partly accounts for her excellent preservation. would have reached an adult height of around 6 feet. Although she has often been nicknamed Lucy's baby, the specimen has been dated at 3.3 million years ago, approximately 120,000 years older than "Lucy". The Nariokotome Homo erectus specimen ____.
