A Brief History Of The Homo Species That Changed Human Evolution Forever: Homo Habilis [65] It was once thought that Turkana boy had 6 lumbar vertebra instead of the 5 seen in modern humans and 11 instead of 12 thoracic vertebrae, but this has since been revised, and the specimen is now considered to have exhibited a humanlike curvature of the spine (lordosis) and the same number of respective vertebrae. [citation needed] It has been proposed that Asian H. erectus have several unique characteristics from non-Asian populations (autapomorphies), but there is no clear consensus on what these characteristics are or if they are indeed limited to only Asia. Please select which sections you would like to print: Professor of Anthropology, State University of New York at Binghamton. Slightly smaller teeth; front teeth still large; When comparing Homo erectus, archaic Homo sapiens, and anatomically modern Homo sapiens across several anatomical features, one can see quite clearly that archaic Homo sapiens are intermediate in their physical form. And this increase in the upper limit seems to be more pronounced in European populations which may be a result of correlated increases in body size in addition to climatic factors'. WebOne of the traits most commonly associated with Homo erectus is an increase in body size. Based on this, he concluded that there is not a significant disparity in intelligence between H. erectus and modern humans and that, for the last 300,000 years, increasing intelligence has not been a major influencer of cultural evolution. Which of the following defines Homo erectus Maintaining fires would require firekeepers to have knowledge on slow-burning materials such as dung. [53][78], Java Man's dispersal through Southeast Asia coincides with the extirpation of the giant turtle Megalochelys, possibly due to overhunting as the turtle would have been an easy, slow-moving target which could have been stored for quite some time. 1. [15] Homo fossils have also been reported from nearby caves, but their species designation has been a tumultuous discussion. It was hypothesised that intense physical activity could have induced bone thickening, but in 1970, human biologist Stanley Marion Garn demonstrated there is a low correlation between the two at least in modern humans. [104] The earliest evidence of hearths comes from Gesher Benot Ya'aqov, Israel, over 700,000 years ago, where fire is recorded in multiple layers in an area close to water, both uncharacteristic of natural fires. It is possible that they only knew how to maintain fires in certain settings in the landscapes and prepared food some distance away from home, meaning evidence of fire and evidence of hominin activity are spaced far apart. New Evidence from an Old Collection Housed at Uppsala University, Sweden. Cooking makes protein more easily digestible, speeds up nutrient absorption, and destroys food-borne pathogens, which would have increased the environment's natural carrying capacity, allowing group size to expand, causing selective pressure for sociality, requiring greater brain function. [127][128] As it is unclear if H. erectus could have used ochre for any practical application, ochre collection might indicate that H. erectus was the earliest human to have exhibited a sense of aesthetics and to think beyond simply survival. [40] It has also been suggested that H. ergaster instead of H. erectus, or some hybrid between the two, was the immediate ancestor of other archaic humans and modern humans. [67] It is possible that exposed skin only became maladaptive in the Pleistocene, because the increasing tilt of the Earth (which also caused the ice ages) would have increased solar radiation bombardment- which would suggest that hairlessness first emerged in the australopithecines. [16] Beginning in the 1970s, propelled most notably by Richard Leakey, more were being unearthed in East Africa predominantly at the Koobi Fora site, Kenya, and Olduvai Gorge, Tanzania. Author of. A 2011 study suggested that it was H. habilis who reached West Asia from Africa, that early H. erectus developed there, and that early H. erectus would then have dispersed from West Asia to East Asia (Peking Man), Southeast Asia (Java Man), back to Africa (Homo ergaster), and to Europe (Tautavel Man), eventually evolving into modern humans in Africa. This dwelling's base measured about 3m 4m (9.8ft 13.1ft) on the exterior and 3m 2m (9.8ft 6.6ft) on the interior, and is considered to have been a firm surface hut, probably with a vaulted roof made of thick branches or thin poles, supported by a foundation of big rocks and earth, and likely functioned as a winter base camp. In comparison, modern humans with a similar activity level have a DEE of 2,450 calories, of which 33% derives from fat, and 49% of the fat from animals.

This history has been recorded directly if imprecisely by many sites that have yielded fossil remains of H. erectus. [79], The only fossil evidence regarding H. erectus group composition comes from 4 sites outside of Ileret, Kenya, where 97 footprints made 1.5 Mya were likely left by a group of at least 20 individuals. The majority of this regional variation lies in the degree to which fossils have features more closely aligned with Homo erectus or with anatomically modern Homo sapiens. They were mostly formed by natural weathering, but slightly modified to emphasize certain grooves to suggest hairline, limbs, and eyes. If yes, then there was a substantial and sudden increase in female height. To illustrate this point, we will examine three exemplary specimens, one from each of the three continents on which archaic Homo sapiens lived. Homo erectus, (Latin: upright man) extinct species of the human genus (Homo), perhaps an ancestor of modern humans (Homo sapiens). [96], The earliest record of Acheulean technology comes from West Turkana, Kenya 1.76 Mya. [53], In 1999, British anthropologist Richard Wrangham proposed the "cooking hypothesis" which states that H. erectus speciated from the ancestral H. habilis because of fire usage and cooking 2 Million years ago to explain the rapid doubling of brain size between these two species in only a 500,000 year timespan, and the sudden appearance of the typical human body plan. How did the north sectional differences lead to it, having an initial advantage over the south in the context of the Civil War? [29], "Wushan Man" was proposed as Homo erectus wushanensis, but is now thought to be based upon fossilized fragments of an extinct non-hominin ape. However, it is also possible that the energy-expensive guts decreased in size in H. erectus, because the large ape gut is used to synthesize fat by fermenting plant matter which was replaced by dietary animal fat, allowing more energy to be diverted to brain growth. H. erectus would have had considerable leftovers, potentially pointing to food sharing or long-term food preservation (such as by drying) if most of the kill was indeed utilized. 1,200 cc (1,500 cc when including Neanderthals), Projecting nasal bones (bridge of the nose), no midfacial prognathism, Wider nasal aperture and midfacial prognathism, Narrower nasal aperture, no midfacial prognathism, Large brow ridge and large projecting face, Nuchal torus, sagittal keel, thick cranial bone, Projecting occipital bone, often called occipital bun in Neanderthals; intermediate thickness of cranial bone, Small bump on rear of skull, if anything; thin cranial bone. Your response should also include a description of the effects of railroads on the physical environment. [35] However, a 2015 study suggested that H. georgicus represents an earlier, more primitive species of Homo derived from an older dispersal of hominins from Africa, with H. ergaster/erectus possibly deriving from a later dispersal. High-latitude groups are thought to have been predominantly carnivorous, eating soft tissue such as bone marrow or brains, which may have increased survival rates for toothless individuals. [41], In a wider sense, H. erectus had mostly been replaced by H. heidelbergensis by about 300 kya, with possible late survival of H. erectus soloensis in Java an estimated 117-108kya.[1]. This species is accepted as a late example of Homo erectus. Emerging. Significantly, some small brained modern populations showed greater affinity with H. erectus than they did with other large brained and large bodied modern populations. [102] If these early European H. erectus did not have fire, it is largely unclear how they stayed warm, avoided predators, and prepared animal fat and meat for consumption. The large animals were likely scavenged at this site, but the turtles and fish were possibly collected live. This indicates that H. erectus was probably not cognitively comparable to modern humans, and that secondary altricialityan extended childhood and long period of dependency due to the great amount of time required for brain maturationevolved much later in human evolution, perhaps in the modern human/Neanderthal last common ancestor. In 1985, biological anthropologist Gail Kennedy argued for resorption as a result of hyperparathyroidism caused by hypocalcemia (calcium deficiency), a consequence of a dietary shift to low-calcium meat. A. For other uses, see, There was long-standing uncertainty whether. throughout the Old World. [8] "Lemuria" had supposedly sunk below the Indian Ocean, so no fossils could be found to prove this. Archaic Homo sapiens share our species name but are distinguished by the term archaic as a way of recognizing both the long period of time between their appearance and ours, as well as the way in which human traits have continued to evolve over timemaking archaic Homo sapiens look slightly different from us today, despite technically being considered the same species. Use of Fire Oc. In 1960, in Olduvai Gorge two skulls identified as OH12 and OH9, were found to be that of H. erectus with a cranial capacities of 1000 cc and 700 cc. Black lobbied across North America and Europe for funding to continue excavating the site,[11] which has since become the most productive H. erectus site in the world. La Hague: Mouton, 361372. sedentism? A. From which country did the United States purchase the territory of Texas? [76], Based on an average mass of 63kg (139lb) for males and 52.3kg (115lb) for females, the total energy expenditure (TEE)the amount of calories consumed in one daywas estimated to be about 2271.8 and 1909.5 kcal, respectively. H. erectus may have also been the first to use a hunting and gathering food collecting strategy as a response to the increasing dependence on meat. Human entomophagy and therefore an increase in protein consumption through insects has also been proposed as a possible cause. The occipital bone often projected and the cranial bone was of intermediate thickness, somewhat reduced from Homo erectus but not nearly as thin as that of anatomically modern Homo sapiens. [68] It is known that head lice and body lice (the latter can only inhabit clothed individuals) for modern humans diverged about 170 kya, well before modern humans left Africa, meaning clothes were already well in use before encountering cold climates. One of the first uses of animal hide is thought to have been for clothing, and the oldest hide scrapers date to about 780 kya, though this is not indicative of clothing. Due to the transitional nature of archaic Homo sapiens, identifying the time period they are associated with is problematic and complex. [75] It was previously believed that, based on the narrow pelvis of Turkana boy, H. erectus could only safely deliver a baby with a brain volume of about 230cc (14cuin), equating to a similar brain growth rate as modern humans to achieve the average adult brain size of 6001,067cc (36.665.1cuin). WebCorrect answer is option d, As use o . Genetic analysis suggests that high activity in the melanocortin 1 receptor, which would produce dark skin, dates back to 1.2 Mya. Contemporary groups appear to have been interbreeding, so any phylogeny like this only gives a coarse impression of the evolution of Homo, and extinct lineage may have partially continued in other groupings. The earliest claimed fire sites are in Kenya, FxJj20 at Koobi Fora[101][89][102] and GnJi 1/6E in the Chemoigut Formation, as far back as 1.5 Mya,[89][102] and in South Africa, Wonderwerk Cave, 1.7 Mya. [70] A 500300 ka H. erectus specimen from Turkey was diagnosed with the earliest known case of tuberculous meningitis, which is typically exacerbated in dark-skinned people living in higher latitudes due to vitamin D deficiency. [60] It is unclear if sexual dimorphism is at play here since the remains are fragmentary. Replica of lower jaws of Homo erectus from Tautavel, France. [2] Its specimens are among the first recognizable members of the genus Homo. This is similar to that of earlier Homo, despite a marked increase in activity and migratory capacity, likely because the longer legs of H. erectus were more energy-efficient in long-distance movement. Intermediate. The bodies of the mandibles of H. erectus, and all early Homo, are thicker than those of modern humans and all living apes. include. In modern hunter gatherer societies who target large prey items, typically male parties are dispatched to bring down these high-risk animals, and, due to the low success rate, female parties focus on more predictable foods. Omissions? Extinct already,Homo erectusemerged about 2 million years ago and disappeared approximately 143,000 50,000 years ago, depending on the subspecies. These usually cause recurrent lower back pain and sciatica (pain running down the leg), and likely restricted Turkana boy in walking, bending, and other daily activities. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ [88], Dentally, H. erectus mouths were not as versatile as those of ancestor species, capable of processing a narrower range of foods. [46][47] The presence of sagittal, frontal, and coronal keels, which are small crests that run along these suture lines, has been proposed to be evidence of significant thickening of the skull, specifically the cranial vault. heidelbergensis. [91], H. erectus is credited with inventing the Acheulean stone tool industry, succeeding the Oldowan industry,[92][93] and were the first to make lithic flakes bigger than 10cm (3.9in), and hand axes (which includes bifacial tools with only 2 sides, such as picks, knives, and cleavers). The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. These all indicate that the H. erectus mouth was less capable of processing hard foods and more at shearing through tougher foods, thus reducing the variety of foods it could process, likely as a response to tool use. WebHomo erectus is the most long-lived species of Homo, having survived for almost two million years. Which of the following traits is NOT unique to Homo erectus? [45], Homo erectus featured a flat face compared to earlier hominins; pronounced brow ridge; and a low, flat skull. Zanolli, Clment, et al. Many skullcaps bear usually debilitating fractures, such as the Peking Man skull X, yet they can show signs of surviving and healing. Darwin had pointed out that chimpanzees and gorillas, humans' closest relatives, evolved and exist only in Africa. Archaic Homo sapiens mark an important chapter in the human lineage, bridging more ancestral forms, such as Homo erectus, with modern Homo sapiens. The Sangiran site yielded the best preserved Java Man skull. Kennedy could not explain why the calcium metabolism of H. erectus never adjusted. Roach, & Richmond. Asian populations of H.erectus may be ancestral to H.floresiensis[4] and possibly to H. At 6176cm (22.5ft) intervals, rocks were piled up to 1523cm (69in) high. [62], H. erectus had about the same limb configurations and proportions as modern humans, implying humanlike locomotion,[63] the first in the Homo lineage. The braincase was low, the forehead was receded, and the nose, jaws, and palate were wide. H. erectus appears to have been the first human species to control fire, some 1,000,000 years ago. Overall, H. erectus brain size varies from 5461,251cc (33.376.3cuin),[51] which is greater than the range of variation seen in modern humans and chimps, though less than that of gorillas. [17], Archaic human fossils unearthed across Europe used to be assigned to H. erectus, but have since been separated as H. heidelbergensis as a result of namely British physical anthropologist Chris Stringer's work. 1. However, later Sangiran teeth seem to reduce in size, which could indicate a secondary colonization event of Java by the Zhoukoudian or some closely related population. Web13. D. longer arms and curved finger bones. This follows the trends first seen in Homo erectus for some features and in other features having early, less developed forms of traits more clearly seen in modern Homo sapiens. Calvaria "Sangiran II" original, collection Koenigswald, Senckenberg Museum. Size, nonetheless, ranged widely from 146185cm (4ft 9in 6ft 1in) in height and 4068kg (88150lb) in weight. erectus. For simplicity we are going to lump them all together under the heading of archaic Homo sapiens and discuss them as a unit, with the exception of a particularly unique and well-known population living in Europe and West Asia known as the Neanderthals, which we will examine separately. Though brain size certainly exceeds that of ancestor species, capacity varied widely depending on the population. [32], Due to such a wide range of variation, it has been suggested that the ancient H. rudolfensis and H. habilis should be considered early varieties of H. Oldowan lithics are also known from the site, and the two seemed to coexist for some time. [5] The last known population of H.erectus is H. e. soloensis from Java, around 117,000108,000 years ago.[1]. Homo erectus. [102][104][53][78] It is possible that firestarting was invented and lost and reinvented multiple times and independently by different communities rather than being invented in one place and spreading throughout the world. Skull Shape. Please refer to the appropriate style manual or other sources if you have any questions. Emeritus Professor of Anatomy and Human Biology, University of the Witwatersrand, Johannesburg. erectus. A. germs and viruses adapt more quickly to infect humans, C. people travel further in search of food, 5. B. Homo naledi evolved from the robust Australopithecines. Congress writes laws nominating judges; the president confirms judicial nominations. [138] Increasing brain size and cultural complexity in tandem with technological refinement, and the hypothesis that articulate Neanderthals and modern humans may have inherited speech capabilities from the last common ancestor, could possibly indicate that H. erectus used some proto-language and built the basic framework which fully fledged languages would eventually be built around. From the neck down, Homo erectus was. [89][90] Artificial lighting may have also made sleeping on the ground instead of the trees possible by keeping terrestrial predators at bay. Corrections? The original specimens were lost during the Second Sino-Japanese War after an attempt to smuggle them out of China for safekeeping. erectus? Globular. interpreted? "An explanation for the diastema of Javan erectus Skull IV". Later human species are postulated to have used ochre as body paint, but in the case of H. erectus, it is contested if body paint was used so early in time. While the general features of archaic Homo sapiens, identified earlier, are present in the fossils of this time period, there are significant regional differences. [73][74], The 1.8 Ma Mojokerto child specimen from Java, who died at about 1 year of age, presented 7284% of the average adult brain size, which is more similar to the faster brain growth trajectory of great apes than modern humans.

[56] H. erectus tracks near Ileret, Kenya, also indicate a human gait. The mandibular body resists torsion from the bite force or chewing, meaning their jaws could produce unusually powerful stresses while eating, but the practical application of this is unclear. One partial crania from Dali, China, is representative of archaic Homo sapiens in Asia, including large and robust features with heavy brow ridges, akin to what is seen in Homo erectus, and a large cranial capacity intermediate between Homo erectus and anatomically modern Homo sapiens. In 2001, American anthropologists Bruce Latimer and James Ohman concluded that Turkana boy was afflicted by skeletal dysplasia and scoliosis. "Cranial Vault Thickness in Primates: Homo Erectus Does Not Have Uniquely Thick Vault Bones. Forehead. Regardless of where it first evolved, the species seems to have dispersed quickly, starting about 1.9 million years ago (mya) near the middle of the Pleistocene Epoch, moving through the African tropics, Europe, South Asia, and Southeast Asia. Similarities between Java Man and Peking Man led Ernst Mayr to rename both as Homo erectus in 1950. Homo rhodesiensis/heidelbergensis (incl. To identify a set of features that is unique to the group archaic Homo sapiens is a challenging task, due to both individual variationthese developments were not all present to the same degree in all individualsand the transitional nature of their features. Web1. [49] American psychologist Lucia Jacobs hypothesized that the projecting nose instead allowed for distinguishing the direction different smells come from (stereo olfaction) to facilitate navigation and long-distance migration. This more aligns with the conclusions drawn from the Mojokerto child. "Inner Tooth Morphology of Homo Erectus from Zhoukoudian. [78] Nonetheless, H. erectus diet likely varied widely depending upon location. [59], Because H. erectus males and females are thought to have been about the same size compared to other great apes (exhibit less size-specific sexual dimorphism), it is generally hypothesised that they lived in a monogamous society, as reduced sexual dimorphism in primates is typically correlated with this mating system. [99] Spherical stones, measuring 612cm (2.44.7in) in diameter, are frequently found in African and Chinese Lower Paleolithic sites, and were potentially used as bolas; if correct, this would indicate string and cordage technology. C. occipital torus Such versatility may have permitted H. erectus to inhabit a range of different environments, and migrate beyond Africa. [151] It is indicated how many million years ago the clades diverged. Livestock that grazes on volcanic ash ridden fields typically die of acute intoxication within a few days or weeks. It also overlooks the fact that some modern populations have not seen any dramatic brain size increase relative to H. erectus with most of the increase occurring in European populations, which has the result of obscuring interpopulational variation. [90], Artificial lighting may have led to increased waking hoursmodern humans have about a 16-hour waking period, whereas other apes are generally awake from only sunup to sundownand these additional hours were probably used for socializing. Homo erectus (/homo rkts/; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2million years ago. C. occipital torus. [37][38], It is debated whether the African H. e. ergaster is a separate species (and that H. erectus evolved in Asia, then migrated to Africa),[39] or is the African form (sensu lato) of H. erectus (sensu stricto).

which of the following is not a defining trait of homo erectus:
A Brief History Of The Homo Species That Changed Human Evolution Forever: Homo Habilis [65] It was once thought that Turkana boy had 6 lumbar vertebra instead of the 5 seen in modern humans and 11 instead of 12 thoracic vertebrae, but this has since been revised, and the specimen is now considered to have exhibited a humanlike curvature of the spine (lordosis) and the same number of respective vertebrae. [citation needed] It has been proposed that Asian H. erectus have several unique characteristics from non-Asian populations (autapomorphies), but there is no clear consensus on what these characteristics are or if they are indeed limited to only Asia. Please select which sections you would like to print: Professor of Anthropology, State University of New York at Binghamton. Slightly smaller teeth; front teeth still large; When comparing Homo erectus, archaic Homo sapiens, and anatomically modern Homo sapiens across several anatomical features, one can see quite clearly that archaic Homo sapiens are intermediate in their physical form. And this increase in the upper limit seems to be more pronounced in European populations which may be a result of correlated increases in body size in addition to climatic factors'. WebOne of the traits most commonly associated with Homo erectus is an increase in body size. Based on this, he concluded that there is not a significant disparity in intelligence between H. erectus and modern humans and that, for the last 300,000 years, increasing intelligence has not been a major influencer of cultural evolution. Which of the following defines Homo erectus Maintaining fires would require firekeepers to have knowledge on slow-burning materials such as dung. [53][78], Java Man's dispersal through Southeast Asia coincides with the extirpation of the giant turtle Megalochelys, possibly due to overhunting as the turtle would have been an easy, slow-moving target which could have been stored for quite some time. 1. [15] Homo fossils have also been reported from nearby caves, but their species designation has been a tumultuous discussion. It was hypothesised that intense physical activity could have induced bone thickening, but in 1970, human biologist Stanley Marion Garn demonstrated there is a low correlation between the two at least in modern humans. [104] The earliest evidence of hearths comes from Gesher Benot Ya'aqov, Israel, over 700,000 years ago, where fire is recorded in multiple layers in an area close to water, both uncharacteristic of natural fires. It is possible that they only knew how to maintain fires in certain settings in the landscapes and prepared food some distance away from home, meaning evidence of fire and evidence of hominin activity are spaced far apart. New Evidence from an Old Collection Housed at Uppsala University, Sweden. Cooking makes protein more easily digestible, speeds up nutrient absorption, and destroys food-borne pathogens, which would have increased the environment's natural carrying capacity, allowing group size to expand, causing selective pressure for sociality, requiring greater brain function. [127][128] As it is unclear if H. erectus could have used ochre for any practical application, ochre collection might indicate that H. erectus was the earliest human to have exhibited a sense of aesthetics and to think beyond simply survival. [40] It has also been suggested that H. ergaster instead of H. erectus, or some hybrid between the two, was the immediate ancestor of other archaic humans and modern humans. [67] It is possible that exposed skin only became maladaptive in the Pleistocene, because the increasing tilt of the Earth (which also caused the ice ages) would have increased solar radiation bombardment- which would suggest that hairlessness first emerged in the australopithecines. [16] Beginning in the 1970s, propelled most notably by Richard Leakey, more were being unearthed in East Africa predominantly at the Koobi Fora site, Kenya, and Olduvai Gorge, Tanzania. Author of. A 2011 study suggested that it was H. habilis who reached West Asia from Africa, that early H. erectus developed there, and that early H. erectus would then have dispersed from West Asia to East Asia (Peking Man), Southeast Asia (Java Man), back to Africa (Homo ergaster), and to Europe (Tautavel Man), eventually evolving into modern humans in Africa. This dwelling's base measured about 3m 4m (9.8ft 13.1ft) on the exterior and 3m 2m (9.8ft 6.6ft) on the interior, and is considered to have been a firm surface hut, probably with a vaulted roof made of thick branches or thin poles, supported by a foundation of big rocks and earth, and likely functioned as a winter base camp. In comparison, modern humans with a similar activity level have a DEE of 2,450 calories, of which 33% derives from fat, and 49% of the fat from animals. You can specify conditions of storing and accessing cookies in your browser, Answer choices? Homo sapiens)). This history has been recorded directly if imprecisely by many sites that have yielded fossil remains of H. erectus. [79], The only fossil evidence regarding H. erectus group composition comes from 4 sites outside of Ileret, Kenya, where 97 footprints made 1.5 Mya were likely left by a group of at least 20 individuals. The majority of this regional variation lies in the degree to which fossils have features more closely aligned with Homo erectus or with anatomically modern Homo sapiens. They were mostly formed by natural weathering, but slightly modified to emphasize certain grooves to suggest hairline, limbs, and eyes. If yes, then there was a substantial and sudden increase in female height. To illustrate this point, we will examine three exemplary specimens, one from each of the three continents on which archaic Homo sapiens lived. Homo erectus, (Latin: upright man) extinct species of the human genus (Homo), perhaps an ancestor of modern humans (Homo sapiens). [96], The earliest record of Acheulean technology comes from West Turkana, Kenya 1.76 Mya. [53], In 1999, British anthropologist Richard Wrangham proposed the "cooking hypothesis" which states that H. erectus speciated from the ancestral H. habilis because of fire usage and cooking 2 Million years ago to explain the rapid doubling of brain size between these two species in only a 500,000 year timespan, and the sudden appearance of the typical human body plan. How did the north sectional differences lead to it, having an initial advantage over the south in the context of the Civil War? [29], "Wushan Man" was proposed as Homo erectus wushanensis, but is now thought to be based upon fossilized fragments of an extinct non-hominin ape. However, it is also possible that the energy-expensive guts decreased in size in H. erectus, because the large ape gut is used to synthesize fat by fermenting plant matter which was replaced by dietary animal fat, allowing more energy to be diverted to brain growth. H. erectus would have had considerable leftovers, potentially pointing to food sharing or long-term food preservation (such as by drying) if most of the kill was indeed utilized. 1,200 cc (1,500 cc when including Neanderthals), Projecting nasal bones (bridge of the nose), no midfacial prognathism, Wider nasal aperture and midfacial prognathism, Narrower nasal aperture, no midfacial prognathism, Large brow ridge and large projecting face, Nuchal torus, sagittal keel, thick cranial bone, Projecting occipital bone, often called occipital bun in Neanderthals; intermediate thickness of cranial bone, Small bump on rear of skull, if anything; thin cranial bone. Your response should also include a description of the effects of railroads on the physical environment. [35] However, a 2015 study suggested that H. georgicus represents an earlier, more primitive species of Homo derived from an older dispersal of hominins from Africa, with H. ergaster/erectus possibly deriving from a later dispersal. High-latitude groups are thought to have been predominantly carnivorous, eating soft tissue such as bone marrow or brains, which may have increased survival rates for toothless individuals. [41], In a wider sense, H. erectus had mostly been replaced by H. heidelbergensis by about 300 kya, with possible late survival of H. erectus soloensis in Java an estimated 117-108kya.[1]. This species is accepted as a late example of Homo erectus. Emerging. Significantly, some small brained modern populations showed greater affinity with H. erectus than they did with other large brained and large bodied modern populations. [102] If these early European H. erectus did not have fire, it is largely unclear how they stayed warm, avoided predators, and prepared animal fat and meat for consumption. The large animals were likely scavenged at this site, but the turtles and fish were possibly collected live. This indicates that H. erectus was probably not cognitively comparable to modern humans, and that secondary altricialityan extended childhood and long period of dependency due to the great amount of time required for brain maturationevolved much later in human evolution, perhaps in the modern human/Neanderthal last common ancestor. In 1985, biological anthropologist Gail Kennedy argued for resorption as a result of hyperparathyroidism caused by hypocalcemia (calcium deficiency), a consequence of a dietary shift to low-calcium meat. A. For other uses, see, There was long-standing uncertainty whether. throughout the Old World. [8] "Lemuria" had supposedly sunk below the Indian Ocean, so no fossils could be found to prove this. Archaic Homo sapiens share our species name but are distinguished by the term archaic as a way of recognizing both the long period of time between their appearance and ours, as well as the way in which human traits have continued to evolve over timemaking archaic Homo sapiens look slightly different from us today, despite technically being considered the same species. Use of Fire Oc. In 1960, in Olduvai Gorge two skulls identified as OH12 and OH9, were found to be that of H. erectus with a cranial capacities of 1000 cc and 700 cc. Black lobbied across North America and Europe for funding to continue excavating the site,[11] which has since become the most productive H. erectus site in the world. La Hague: Mouton, 361372. sedentism? A. From which country did the United States purchase the territory of Texas? [76], Based on an average mass of 63kg (139lb) for males and 52.3kg (115lb) for females, the total energy expenditure (TEE)the amount of calories consumed in one daywas estimated to be about 2271.8 and 1909.5 kcal, respectively. H. erectus may have also been the first to use a hunting and gathering food collecting strategy as a response to the increasing dependence on meat. Human entomophagy and therefore an increase in protein consumption through insects has also been proposed as a possible cause. The occipital bone often projected and the cranial bone was of intermediate thickness, somewhat reduced from Homo erectus but not nearly as thin as that of anatomically modern Homo sapiens. [68] It is known that head lice and body lice (the latter can only inhabit clothed individuals) for modern humans diverged about 170 kya, well before modern humans left Africa, meaning clothes were already well in use before encountering cold climates. One of the first uses of animal hide is thought to have been for clothing, and the oldest hide scrapers date to about 780 kya, though this is not indicative of clothing. Due to the transitional nature of archaic Homo sapiens, identifying the time period they are associated with is problematic and complex. [75] It was previously believed that, based on the narrow pelvis of Turkana boy, H. erectus could only safely deliver a baby with a brain volume of about 230cc (14cuin), equating to a similar brain growth rate as modern humans to achieve the average adult brain size of 6001,067cc (36.665.1cuin). WebCorrect answer is option d, As use o . Genetic analysis suggests that high activity in the melanocortin 1 receptor, which would produce dark skin, dates back to 1.2 Mya. Contemporary groups appear to have been interbreeding, so any phylogeny like this only gives a coarse impression of the evolution of Homo, and extinct lineage may have partially continued in other groupings. The earliest claimed fire sites are in Kenya, FxJj20 at Koobi Fora[101][89][102] and GnJi 1/6E in the Chemoigut Formation, as far back as 1.5 Mya,[89][102] and in South Africa, Wonderwerk Cave, 1.7 Mya. [70] A 500300 ka H. erectus specimen from Turkey was diagnosed with the earliest known case of tuberculous meningitis, which is typically exacerbated in dark-skinned people living in higher latitudes due to vitamin D deficiency. [60] It is unclear if sexual dimorphism is at play here since the remains are fragmentary. Replica of lower jaws of Homo erectus from Tautavel, France. [2] Its specimens are among the first recognizable members of the genus Homo. This is similar to that of earlier Homo, despite a marked increase in activity and migratory capacity, likely because the longer legs of H. erectus were more energy-efficient in long-distance movement. Intermediate. The bodies of the mandibles of H. erectus, and all early Homo, are thicker than those of modern humans and all living apes. include. In modern hunter gatherer societies who target large prey items, typically male parties are dispatched to bring down these high-risk animals, and, due to the low success rate, female parties focus on more predictable foods. Omissions? Extinct already,Homo erectusemerged about 2 million years ago and disappeared approximately 143,000 50,000 years ago, depending on the subspecies. These usually cause recurrent lower back pain and sciatica (pain running down the leg), and likely restricted Turkana boy in walking, bending, and other daily activities. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ [88], Dentally, H. erectus mouths were not as versatile as those of ancestor species, capable of processing a narrower range of foods. [46][47] The presence of sagittal, frontal, and coronal keels, which are small crests that run along these suture lines, has been proposed to be evidence of significant thickening of the skull, specifically the cranial vault. heidelbergensis. [91], H. erectus is credited with inventing the Acheulean stone tool industry, succeeding the Oldowan industry,[92][93] and were the first to make lithic flakes bigger than 10cm (3.9in), and hand axes (which includes bifacial tools with only 2 sides, such as picks, knives, and cleavers). The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. These all indicate that the H. erectus mouth was less capable of processing hard foods and more at shearing through tougher foods, thus reducing the variety of foods it could process, likely as a response to tool use. WebHomo erectus is the most long-lived species of Homo, having survived for almost two million years. Which of the following traits is NOT unique to Homo erectus? [45], Homo erectus featured a flat face compared to earlier hominins; pronounced brow ridge; and a low, flat skull. Zanolli, Clment, et al. Many skullcaps bear usually debilitating fractures, such as the Peking Man skull X, yet they can show signs of surviving and healing. Darwin had pointed out that chimpanzees and gorillas, humans' closest relatives, evolved and exist only in Africa. Archaic Homo sapiens mark an important chapter in the human lineage, bridging more ancestral forms, such as Homo erectus, with modern Homo sapiens. The Sangiran site yielded the best preserved Java Man skull. Kennedy could not explain why the calcium metabolism of H. erectus never adjusted. Roach, & Richmond. Asian populations of H.erectus may be ancestral to H.floresiensis[4] and possibly to H. At 6176cm (22.5ft) intervals, rocks were piled up to 1523cm (69in) high. [62], H. erectus had about the same limb configurations and proportions as modern humans, implying humanlike locomotion,[63] the first in the Homo lineage. The braincase was low, the forehead was receded, and the nose, jaws, and palate were wide. H. erectus appears to have been the first human species to control fire, some 1,000,000 years ago. Overall, H. erectus brain size varies from 5461,251cc (33.376.3cuin),[51] which is greater than the range of variation seen in modern humans and chimps, though less than that of gorillas. [17], Archaic human fossils unearthed across Europe used to be assigned to H. erectus, but have since been separated as H. heidelbergensis as a result of namely British physical anthropologist Chris Stringer's work. 1. However, later Sangiran teeth seem to reduce in size, which could indicate a secondary colonization event of Java by the Zhoukoudian or some closely related population. Web13. D. longer arms and curved finger bones. This follows the trends first seen in Homo erectus for some features and in other features having early, less developed forms of traits more clearly seen in modern Homo sapiens. Calvaria "Sangiran II" original, collection Koenigswald, Senckenberg Museum. Size, nonetheless, ranged widely from 146185cm (4ft 9in 6ft 1in) in height and 4068kg (88150lb) in weight. erectus. For simplicity we are going to lump them all together under the heading of archaic Homo sapiens and discuss them as a unit, with the exception of a particularly unique and well-known population living in Europe and West Asia known as the Neanderthals, which we will examine separately. Though brain size certainly exceeds that of ancestor species, capacity varied widely depending on the population. [32], Due to such a wide range of variation, it has been suggested that the ancient H. rudolfensis and H. habilis should be considered early varieties of H. Oldowan lithics are also known from the site, and the two seemed to coexist for some time. [5] The last known population of H.erectus is H. e. soloensis from Java, around 117,000108,000 years ago.[1]. Homo erectus. [102][104][53][78] It is possible that firestarting was invented and lost and reinvented multiple times and independently by different communities rather than being invented in one place and spreading throughout the world. Skull Shape. Please refer to the appropriate style manual or other sources if you have any questions. Emeritus Professor of Anatomy and Human Biology, University of the Witwatersrand, Johannesburg. erectus. A. germs and viruses adapt more quickly to infect humans, C. people travel further in search of food, 5. B. Homo naledi evolved from the robust Australopithecines. Congress writes laws nominating judges; the president confirms judicial nominations. [138] Increasing brain size and cultural complexity in tandem with technological refinement, and the hypothesis that articulate Neanderthals and modern humans may have inherited speech capabilities from the last common ancestor, could possibly indicate that H. erectus used some proto-language and built the basic framework which fully fledged languages would eventually be built around. From the neck down, Homo erectus was. [89][90] Artificial lighting may have also made sleeping on the ground instead of the trees possible by keeping terrestrial predators at bay. Corrections? The original specimens were lost during the Second Sino-Japanese War after an attempt to smuggle them out of China for safekeeping. erectus? Globular. interpreted? "An explanation for the diastema of Javan erectus Skull IV". Later human species are postulated to have used ochre as body paint, but in the case of H. erectus, it is contested if body paint was used so early in time. While the general features of archaic Homo sapiens, identified earlier, are present in the fossils of this time period, there are significant regional differences. [73][74], The 1.8 Ma Mojokerto child specimen from Java, who died at about 1 year of age, presented 7284% of the average adult brain size, which is more similar to the faster brain growth trajectory of great apes than modern humans.

[56] H. erectus tracks near Ileret, Kenya, also indicate a human gait. The mandibular body resists torsion from the bite force or chewing, meaning their jaws could produce unusually powerful stresses while eating, but the practical application of this is unclear. One partial crania from Dali, China, is representative of archaic Homo sapiens in Asia, including large and robust features with heavy brow ridges, akin to what is seen in Homo erectus, and a large cranial capacity intermediate between Homo erectus and anatomically modern Homo sapiens. In 2001, American anthropologists Bruce Latimer and James Ohman concluded that Turkana boy was afflicted by skeletal dysplasia and scoliosis. "Cranial Vault Thickness in Primates: Homo Erectus Does Not Have Uniquely Thick Vault Bones. Forehead. Regardless of where it first evolved, the species seems to have dispersed quickly, starting about 1.9 million years ago (mya) near the middle of the Pleistocene Epoch, moving through the African tropics, Europe, South Asia, and Southeast Asia. Similarities between Java Man and Peking Man led Ernst Mayr to rename both as Homo erectus in 1950. Homo rhodesiensis/heidelbergensis (incl. To identify a set of features that is unique to the group archaic Homo sapiens is a challenging task, due to both individual variationthese developments were not all present to the same degree in all individualsand the transitional nature of their features. Web1. [49] American psychologist Lucia Jacobs hypothesized that the projecting nose instead allowed for distinguishing the direction different smells come from (stereo olfaction) to facilitate navigation and long-distance migration. This more aligns with the conclusions drawn from the Mojokerto child. "Inner Tooth Morphology of Homo Erectus from Zhoukoudian. [78] Nonetheless, H. erectus diet likely varied widely depending upon location. [59], Because H. erectus males and females are thought to have been about the same size compared to other great apes (exhibit less size-specific sexual dimorphism), it is generally hypothesised that they lived in a monogamous society, as reduced sexual dimorphism in primates is typically correlated with this mating system. [99] Spherical stones, measuring 612cm (2.44.7in) in diameter, are frequently found in African and Chinese Lower Paleolithic sites, and were potentially used as bolas; if correct, this would indicate string and cordage technology. C. occipital torus Such versatility may have permitted H. erectus to inhabit a range of different environments, and migrate beyond Africa. [151] It is indicated how many million years ago the clades diverged. Livestock that grazes on volcanic ash ridden fields typically die of acute intoxication within a few days or weeks. It also overlooks the fact that some modern populations have not seen any dramatic brain size increase relative to H. erectus with most of the increase occurring in European populations, which has the result of obscuring interpopulational variation. [90], Artificial lighting may have led to increased waking hoursmodern humans have about a 16-hour waking period, whereas other apes are generally awake from only sunup to sundownand these additional hours were probably used for socializing. Homo erectus (/homo rkts/; meaning "upright man") is an extinct species of archaic human from the Pleistocene, with its earliest occurrence about 2million years ago. C. occipital torus. [37][38], It is debated whether the African H. e. ergaster is a separate species (and that H. erectus evolved in Asia, then migrated to Africa),[39] or is the African form (sensu lato) of H. erectus (sensu stricto).

[53][78], Java Man's dispersal through Southeast Asia coincides with the extirpation of the giant turtle Megalochelys, possibly due to overhunting as the turtle would have been an easy, slow-moving target which could have been stored for quite some time. 1. [15] Homo fossils have also been reported from nearby caves, but their species designation has been a tumultuous discussion. It was hypothesised that intense physical activity could have induced bone thickening, but in 1970, human biologist Stanley Marion Garn demonstrated there is a low correlation between the two at least in modern humans. [104] The earliest evidence of hearths comes from Gesher Benot Ya'aqov, Israel, over 700,000 years ago, where fire is recorded in multiple layers in an area close to water, both uncharacteristic of natural fires. It is possible that they only knew how to maintain fires in certain settings in the landscapes and prepared food some distance away from home, meaning evidence of fire and evidence of hominin activity are spaced far apart. New Evidence from an Old Collection Housed at Uppsala University, Sweden. Cooking makes protein more easily digestible, speeds up nutrient absorption, and destroys food-borne pathogens, which would have increased the environment's natural carrying capacity, allowing group size to expand, causing selective pressure for sociality, requiring greater brain function. [127][128] As it is unclear if H. erectus could have used ochre for any practical application, ochre collection might indicate that H. erectus was the earliest human to have exhibited a sense of aesthetics and to think beyond simply survival. [40] It has also been suggested that H. ergaster instead of H. erectus, or some hybrid between the two, was the immediate ancestor of other archaic humans and modern humans.
