paranthropus robustus habitat

January 25, 2021

[5] In the spirit of tightening splitting criteria for hominin taxa, in 1954, Robinson suggested demoting "P. crassidens" to subspecies level as "P. r. crassidens", and also moved the Indonesian Meganthropus into the genus as "P. TM 1517 consists of a partial cranium, associated mandible, and several postcranial elements. Името му се дължи на палеонтолога Робер Брум, който открива вида в Южна Африка през 1938 г. Estimated male-female size disparity in P. robustus is comparable to gorillas (based on facial dimensions), and younger males were less robust than older males (delayed maturity is also exhibited in gorillas). robustus. [42] SKX 3602 exhibits robust radial styloid processes near the hand which indicate strong brachioradialis muscles and extensor retinaculae. SK 62's growth trajectory is more similar to that of gorillas, whose roots typically measure 7 mm (0.28 in) when emerging from the gums. erectus. McKinley agreed with Mann that P. robustus may have had a prolonged childhood. They suggested the setup would have increased blood flow to the internal vertebral venous plexuses or internal jugular vein, and was thus related to the reorganisation of the blood vessels supplying the head as an immediate response to bipedalism, which relaxed as bipedalism became more developed. [95] It is possible that South Africa was a refugium for Australopithecus until about 2 million years ago with the beginning of major climatic variability and volatility, and potentially competition with Homo and Paranthropus. In 1979, a year after describing A. afarensis from East Africa, anthropologists Donald Johanson and Tim D. White suggested that A. afarensis was instead the last common ancestor between Homo and Paranthropus, and A. africanus was the earliest member of the Paranthropus lineage or at least was ancestral to P. robustus, because A. africanus inhabited South Africa before P. robustus, and A. afarensis was at the time the oldest known hominin species at roughly 3.5 million years old. [67] Similarly, in 2016, Polish anthropologist Katarzyna Kaszycka rebutted that, among primates, delayed maturity is also exhibited in the rhesus monkey which has a multi-male society, and may not be an accurate indicator of social structure. [40], The distal (lower) humerus of P. robustus falls within the variation of both modern humans and chimps, as the distal humerus is quite similar between humans and chimps. Because the majority of sexed P. robustus specimens are male (or at least presumed male), males seem to have had a higher mortality rate than females. However, for chimps, he got strongly inaccurate results when compared to actual data for newborn brain size, weaning age, and birth interval, and for humans all metrics except birth interval. The first remains, a partial skull including a part of the jawbone (TM 1517), were discovered in June 1938 at the Kromdraai cave site, South Africa, by local schoolboy Gert Terblanche. Paranthropus robustus was the first of the robust Paranthropus australopithecines to be found (the other two robust australopithecines are Paranthropus aethiopicus and Paranthropus boisei). "[85] In 1985, British biologists Paul H. Harvey and Tim Clutton-Brock came up with equations relating body size to life history events for primates, which McHenry applied to australopithecines in 1994. This week, we saw a short paper in Science on Paranthropus robustus sexual dimorphism and the implications the differences between sexes had on this early hominid social behavior. [81] In response, in 1971, biologist Kelton McKinley repeated Mann's process with more specimens, and (including P. boisei) reported an average of 18 years. In 1938, Robert Broom discovered the first Paranthropus robustus material at the site of Swartkrans, South Africa. Uranium–lead dating reports intervals of 3.21–0.45 million years ago for Member 1 (a very large error range), 1.65–1.07 million years ago for Member 2, and 1.04–0.62 million years ago for Member 3, though more likely the younger side of the estimate; this could mean P. robustus outlived P. [1] Broom began investigating the site, and, a few weeks later, recovered a right distal humerus (the lower part of the upper arm bone), a proximal right ulna (upper part of a lower arm bone), and a distal phalanx bone of the big toe, all of which he assigned to TM 1517. Indtil da det ikke var kendt af de arter, blev opdagelsen gjort ved først, da han købte et fragment af en molær der solgte et barn. (33%). 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. The Paranthropus robustus o Australopithecus robustus Ia adalah spesies hominid yang hidup 1.8 hingga 1.2 juta tahun lalu di Afrika Selatan. Like humans, jaw robustness decreased with age, though it decreased slower in P. The extinction of P. robustus coincided with the Mid-Pleistocene Transition, and the doubling of glacial cycle duration. [63] P. robustus likely also commonly cracked hard foods such as seeds or nuts, as it had a moderate tooth-chipping rate (about 12% in a sample of 239 individuals, as opposed to little to none for P. It is possible this reflects some arboreal activity (movement in the trees) as is controversially postulated in other australopithecines. [60] In 1980, anthropologists Tom Hatley and John Kappelman suggested that early hominins (convergently with bears and pigs) adapted to eating abrasive and calorie-rich underground storage organs (USOs), such as roots and tubers. [1] "Paranthropus" derives from Ancient Greek παρα para beside or alongside; and άνθρωπος ánthropos man. [65], In a sample of 15 P. robustus specimens, all of them exhibited mild to moderate alveolar bone loss resulting from periodontal disease (the wearing away of the bone which supports the teeth due to gum disease). extended their interpretation of the crest to the males of Paranthropus species, with the crest and resultantly larger head (at least in P. boisei) being used for some kind of display. The only potential Homo specimen from Member 3 is KB 5223, but its classification is debated. The two stone tools (either "Developed Oldowan" or "Early Acheulean") from Kromdraai B could possibly be attributed to P. robustus, as Homo has not been confidently identified in this layer, though it is possible that the stone tools were reworked (moved into the layer after the inhabitants had died). Specii Paranthropus robustus A fost localizat la sud de continentul african, în zone tropicale și în pajiști deschise cum ar fi Coopers Cave, Drimolen, Swartkrans, Kromdraai și Gondolin. [96], Drimolen Cave was first discovered to have yielded hominin remains by Keyser in 1992, who, in 8 years, oversaw the recovery of 79 P. robustus specimens. Habitat Vrsta Paranthropus robustusNahajal se je južno od afriške celine, v tropskih območjih in odprtih travnikih, kot so jama Coopers, Drimolen, Swartkrans, Kromdraai in Gondolin.. Die Australopithecina existierten im Pleistozän ungefähr zwischen 3,5 und 1,8 Millionen Jahren vor heute. By the time the first permanent molar erupts, the body of the mandible and the front jaw broadened, and the ramus of the mandible elongated, diverging from the modern human trajectory. Druh Paranthropus robustus Nachádza sa južne od afrického kontinentu, v tropických oblastiach a otvorených lúkach, ako sú jaskyne Coopers, Drimolen, Swartkrans, Kromdraai a Gondolin.. Fosílne zvyšky analyzované v Swartkrans ukazujú, že. The distal phalanges seem to be essentially humanlike. He also found that microwearing on 20 P. boisei molar specimens were indistinguishable from patterning recorded in mandrills, chimps, and orangutans. Australopithecine bone technology was first proposed by Dart in the 1950s with what he termed the "osteodontokeratic culture", which he attributed to A. africanus at Makapansgat dating to 3–2.6 million years ago. Paranthropus boisei was first discovered by Mary Leaky in 1959, and was first termed Zinjanthropus boisei or Zinj. [34] In 1988, Falk and Tobias demonstrated that early hominins (at least A. africanus and P. boisei) could have both an occipital/marginal and transverse/sigmoid systems concurrently or on opposite halves of the skull. [2], While growing, the front part of the jaw in P. robustus is depository (so it grows) whereas the sides are resorptive (so they recede). [67][68], In 2007, anthropologist Charles Lockwood and colleagues pointed out that P. robustus appears to have had pronounced sexual dimorphism, with males notably larger than females. [18] The matter is still debated. [58] Such a strategy is similar to that used by modern gorillas, which can sustain themselves entirely on lower quality fallback foods year-round, as opposed to lighter built chimps (and presumably gracile australopithecines) which require steady access to high quality foods. It is still debated if this is a valid natural grouping (monophyletic) or an invalid grouping of similar-looking hominins (paraphyletic). In human evolution: Hominin habitats Kromdraai, and Drimolen) of P. robustus are associated with open and even arid habitats, but these may not reflect its actual foraging preference. It was described as a new genus and species by Robert Broom of the TransvaalMuseum. [7] This scheme was widely criticised for being too liberal in demarcating species. sagittal crest flat to dish shaped face broad sweeping zygomatics -towards front of face massive cheekbones. [59] Despite subsequent arguments that Paranthropus were not specialist feeders, the predominant consensus in favour of Robinson's initial model did not change for the remainder of the 20th century. This contrasts with East African bone tools which appear to have been modified and directly cut into specific shapes before using. Specii Paranthropus robustus A fost localizat la sud de continentul african, în zone tropicale și în pajiști deschise cum ar fi Coopers Cave, Drimolen, Swartkrans, Kromdraai și Gondolin. [25] Among these are the most complete P. robustus skulls: the presumed female DNH-7 (which also preserved articulated jawbone with almost all the teeth), and presumed male DNH 155. The strontium isotopic ratio 87 Sr/ 86 Sr has been studied in the Sterkfontein Valley of South Africa to infer both habitat usage and residence for a number of early hominins. [102], As an antipredator behaviour, baboons often associate themselves with medium-to-large herbivores, most notably impalas, and it is possible that P. robustus as well as other early hominins which lived in open environments did so also, given they are typically associated with an abundance of medium-to-large bovid and horse remains. [19] It was long assumed that if Paranthropus is a valid genus then P. robustus was the ancestor of P. boisei, but in 1985, anthropologists Alan Walker and Richard Leakey found that the 2.5 million year old East African skull KNM WT 17000—which they assigned to a new species A. aethiopicus—was ancestral to A. boisei (they considered Paranthropus synonymous with Australopithecus), thus establishing the boisei lineage as beginning long before robustus had existed. The cheeks project so far from the face that, when in top-view, the nose appears to sit at the bottom of a concavity (a dished face). Other articles where Australopithecus aethiopicus is discussed: Australopithecus: Australopithecus aethiopicus: Australopithecus aethiopicus (2.7–2.3 mya), formerly known as Paranthropus aethopicus, is the earliest of the so-called robust australopiths, a group that also includes A. robustus and A. boisei (described below). In a harem society, males are more likely to be evicted from the group given higher male–male competition over females, and lone males may have been put at a higher risk of predation. Itu berutang namanya kepada ahli paleontologi Robert Broom, yang membuat penemuan spesies di Afrika Selatan pada tahun 1938. [94], At Swartkrans, P. robustus has been identified from Members 1–3. [79], In 1968, American anthropologist Alan Mann, using dental maturity, stratified P. robustus specimens from Swartkrans into different ages, and found an average of 17.2 years at death (they did not necessarily die from old age), and the oldest specimen was 30–35 years old. Most prominently, Broom and South African palaeontologist John Talbot Robinson continued arguing for the validity of Paranthropus. Even in a multi-male society, it is still possible that males were more likely to be evicted, explaining male-skewed mortality with the same mechanism. KB 6067, therefore, may possibly be basal to (more ancient than) other P. robustus specimens, at least those for which ear morphology is known. Paranthropus robustus in their natural habitat: Wiki Commons. 1. Objev patřil druhu Paranthropus robustus a přišel jen krátce poté, co Raymond A. Its diet included more C 4 biomass than any other hominin studied to date, including its congener Paranthropus robustus from South Africa. He also had to estimate the length of the humerus using the femur assuming a similar degree of sexual dimorphism between P. robustus and humans. Spesies Paranthropus robustus Itu terletak di selatan benua Afrika, di daerah tropis dan padang rumput terbuka seperti Gua Coopers, Drimolen, Swartkrans, Kromdraai dan Gondolin. afarensis. [93], P. robustus also cohabited the Cradle of Humankind with H. ergaster/H. The carnivore assemblage comprises the sabertoothed cats Dinofelis spp. [53] The ear bones of the juvenile KB 6067 from Member 3 is consistent with that of P. robustus, but the dimensions of the cochlea and oval window better align with the more ancient StW 53 from Sterkfontein Member 4 with undetermined species designation. [51] In 1991, McHenry expanded his sample size, and also estimated the living size of Swartkrans specimens by scaling down the dimensions of an average modern human to meet a preserved leg or foot element (he considered the arm measurements too variable among hominins to give accurate estimates). Comparing the ratio to humans, he concluded that P. robustus was a heavily-built species with a height of 140–150 cm (4 ft 7 in–4 ft 11 in) and a weight of 68–91 kg (150–201 lb). [4], In 1948, at the nearby Swartkrans Cave, Broom described "P. crassidens" based on a subadult jaw, SK 6,[5] because Swartkrans and Kromdraai clearly dated to different time intervals based on the diverging animal assemblages in these caves. In contrast, chimps have an incidence rate of 47%, and gorillas as much as 90%, probably due to a diet with a much higher content of tough plants. Based on this, he concluded babies were birthed at intervals of 3 to 4 years using a statistical test to maximise the number of children born. [11] By the 21st century, "P. crassidens" had more or less fallen out of use in favour of P. robustus. [5], The genus Paranthropus (otherwise known as "robust australopithecines", in contrast to the "gracile australopithecines") now also includes the East African P. boisei and P. aethiopicus. The Genus Paranthropus P. boisei P. aethiopicus P. robustus. The posterior semicircular canals of modern humans are thought to aid in stabilisation while running, which could mean P. robustus was not an endurance runner. Males had more heavily built skulls than females. [60], A 2006 carbon isotope analysis suggested that P. robustus subsisted on mainly C4 savanna plants or C3 forest plants depending on the season, which could indicate either seasonal shifts in diet or seasonal migration from forest to savanna. [24] P. robustus has a tall face with slight prognathism (the jaw jutted out somewhat). The pedicles (which jut out diagonally from the vertebra) of the lower lumbar vertebra are much more robust than in other australopithecines and are within the range of humans, and the transverse processes (which jut out to the sides of the vertebra) indicate powerful iliolumbar ligaments. After he decided it was an altogether different species than Australopithecus africanus – a known hominid at the time – he then set out to search for more bones and teeth of this species. A total of 31 specimens representing at least 17 individuals have been recovered. The absence of the baboons T. oswaldi and Dinopithecus could potentially mean Member 3 is older than Sterkfontein Member 5 and Swartkrans Member 1; which, if correct, would invalidate the results from palaeomagnetism, and make these specimens among the oldest representatives of the species. Original Publication: Broom 1938. He showed his finds to paleontologist Robert Broom of the Transvaal Museum, who promptly investigated the site. Habitat. erectus) and humans than other australopithecines. [74] As an alternative to hominin activity, because the bones were not burnt inside the cave, and it is possible that they were naturally burnt in cyclically occurring wildfires (dry savanna grass as well as possible guano or plant accumulation in the cave may have left it susceptible to such a scenario), and then washed into what would become Member 3. erectus were found in the cave, they were unsure which species to attribute the fire to. [33] Regarding the dural venous sinuses, in 1983, Falk and anthropologist Glenn Conroy suggested that, unlike A. africanus or modern humans, all Paranthropus (and A. afarensis) had expanded occipital and marginal (around the foramen magnum) sinuses, completely supplanting the transverse and sigmoid sinuses. erectus as much bigger at 55 kg (121 lb). prometheus"). [13] In 1972, Robinson suggested including Gigantopithecus in "Paranthropinae", with the Miocene Pakistani "G. bilaspurensis" (now Indopithecus) as the ancestor of Paranthropus and the Chinese G. blacki. A partial cranium and mandible of Paranthropus robustus was discovered in 1938 by a schoolboy, 70 km south west of Pretoria in South Africa. discoverer: Robert Broom 1938 South Africa Swartkrans, Kromdragi 2-1 mya. [8] Meganthropus has since been variously reclassified as a synonym of the Asian Homo erectus, "Pithecanthropus dubius", Pongo (orangutans), and so on, and in 2019 it was again argued to be a valid genus. Paranthropus lived in both southern and eastern Africa was associated with stone tool making. Strontium isotopic aspects of Paranthropus robustus teeth; implications for habitat, residence, and growth. Since circular holes in enamel coverage are uniform in size, only present on the molar teeth, and have the same severity across individuals, the PEH may have been a genetic condition. Cumulative frequencies of P. boisei from eastern Africa with contem-poraneous P. robustus from southern Africa, and for T. oswaldi from both eastern and southern Africa. erectus skull KNM ER 3733 (which is considered a human ancestor). The first of these hominids to be found was Paranthropus robustus in 1938 when a jawbone fragment was found in a farm field in South Africa. [105], However, the geographical range of P. robustus in the fossil record is roughly 500 km2 (190 sq mi), whereas the critically endangered eastern gorilla (with the smallest range of any African ape) inhabits 70,000 km2 (27,000 sq mi), the critically endangered western gorilla 700,000 km2 (270,000 sq mi), and the endangered chimp 2,600,000 km2 (1,000,000 sq mi). Collection of the Transvaal Museum, Northern Flagship Institute, Pretoria South Africa. In P. robustus, about 47% of baby teeth and 14% of adult teeth were affected, in comparison to about 6.7% and 4.3% respectively for the combined teeth of A. africanus, A. sediba, early Homo, and H. naledi. The intermediate phalanges are stout and straight like humans, but have stouter bases and better developed flexor impressions. Dart roku 1925 zveřejnil lebku Taungského dítěte, první známý nález australopitéka (druh Australopithecus africanus). He calculated the humerus-to-femur ratio of P. robustus by using the presumed female humerus of STS 7 and comparing it with the presumed male femur of STS 14. He later found material at Kromdraai, and because the molar teeth were more primitive at that site, he changed the species name at Swartkrans to P. crassidens but used P. robustus for the Kromdraai material. africanus and "Pl. This would mean that, like chimps, they often inhabited areas with an average diurnal temperature of 25 °C (77 °F), dropping to 10 or 5 °C (50 or 41 °F) at night. The remains of at least 130 individuals have been found at Swartkrans. Paranthropus robustus is the last of the Paranthropus Group of human ancestors. Etymology: The Greek suffix -anthropus was added to the Greek prefix par- to construct paranthropus, meaning "near man"; the Latin word robustus means "strong" or "powerful". GDA-2—measuring 18.8 mm × 18.1 mm (0.74 in × 0.71 in), an area of 340 mm2 (0.53 sq in)—is exceptionally large for P. robustus, which has a recorded maximum of 290 mm2 (0.45 sq in). The same year he described and named Paranthropus robustus (1938). Discovered in 1938, it was among the first early hominins described, and became the type species for the genus Paranthropus. [86], Based on a sample of 402 teeth, P. robustus seems to have had a low incidence rate of about 12–16% for tertiary dentin, which forms to repair tooth damage caused by excessive wearing or dental cavities. The wrist joint had the same manoeuverability as that of modern humans rather than the greater flexion achieved by non-human apes, but the head of radius (the elbow) seems to have been quite capable of maintaining stability when the forearm was flexed like non-human apes. The premolars are shaped like molars. [79] Regardless if P. robustus followed a human or non-human ape dental development timeframe, the premolars and molars would have had an accelerated growth rate to achieve their massive size. These results, coupled with recent evidence from dental microwear, may indicate that the remarkable craniodental morphology of this taxon represents an adaptation for processing large quantities of low-quality vegetation rather than hard objects. [62] H. ergaster/H. Paranthropus Robustus. Discovered in 1938, it was among the first early hominins described and the first discovered robust australopithecine, and became the type species for the genus Paranthropus. He considered this evidence that another individual had killed TM 1517 by launching the rock as a projectile in either defense or attack, but the most parsimonious explanation is that the rock was deposited during the fossilisation process after TM 1517 had died. He also identified a distal toe phalanx which he believed belonged to a baboon, but has since been associated with TM 1517. This contrasts with other primates which flash the typically enlarged canines in agonistic display (Paranthropus likely did not do this as the canines are comparatively small), though it is also possible that the crest is only so prominent in male gorillas and orangutans because they require larger temporalis muscles to achieve a wider gape to better display the canines. Discovery Date: 8 Jun 1938. P. robustus society may have been patrilocal, with adult females more likely to leave the group than males, but males may have been more likely to be evicted as indicated by higher male mortality rates and assumed increased risk of predation to solitary individuals. American palaeoanthropologist Frederick E. Grine is the primary opponent of synonymisation of the two species. Proponents of paraphyly allocate these three species to the genus Australopithecus as A. boisei, A. aethiopicus, and A. However, they had not used a … [27] In 1972, American physical anthropologist Ralph Holloway measured the skullcap SK 1585, which is missing part of the frontal bone, and reported a volume of about 530 cc. For P. robustus, he reported newborn brain size of 175 cc and weight of 1.9 kg (4.2 lb), gestation 7.6 months, weaning after 30.1 months of age, maturation age 9.7 years, breeding age 11.4 years, birth interval 45 months, and lifespan 43.3 years. Pronunciation: pair-RAN-thrəp-pəs or (PAIR-an-THRŌPE-pəs) rō-BUST-əs. [35], Few vertebrae are assigned to P. robustus. erectus appears to have consumed about the same proportion of C3 to C4 based foods as P. He gave the remains to South African conservationist Charles Sydney Barlow, who then relayed them to South African palaeontologist Robert Broom. The jaws are the main argument for monophyly, but jaw anatomy is strongly influenced by diet and environment, and could have evolved independently in P. robustus and P. boisei. Sampai saat itu tidak diketahui spesies, temuan itu … Paranthropus boisei and Paranthropus robustus lived between 1.0 and 2.3 million years ago. [12] Primarily influenced by the mid-century opinions of Jewish German anthropologist Franz Weidenreich and German-Dutch palaeontologist Ralph von Koenigswald that Gigantopithecus was, respectively, the direct ancestor of the Asian H. erectus or closely related, much debate followed over whether Gigantopithecus was a hominin or a non-human ape. [84] In response, Leutenegger pointed out that apes have highly variable foetal growth rates, and "estimates on gestation periods based on this rate and birth weight are useless. Growth was most marked between the eruptions of the first and second permanent molars, most notably in terms of the distance from the back of the mouth to the front of the mouth, probably to make room for the massive postcanine teeth. Paranthropus walkeri lived between 2.3 and 2.7 million years ago. 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. [13], In 1949, also in Swartkrans Cave, Broom and Robinson found a mandible which they preliminary described as "intermediate between one of the ape-men and true man," classifying it as a new genus and species "Telanthropus capensis". In contrast, he reported a very small build for A. africanus (which he referred to as "Homo" africanus) and speculated it had some cultural and hunting abilities, being a member of the human lineage, which "paranthropines" lacked. In modern apes (including humans), dental development trajectory is strongly correlated with life history and overall growth rate, but it is possible that early hominins simply had a faster dental trajectory but a slower life history due to environmental factors, such as early weaning age as is exemplified in modern indriid lemurs. [14] With the popularisation of cladistics by the late 1970s to 1980s, and better resolution on how Miocene apes relate to later apes, Gigantopithecus was entirely removed from Homininae, and is now placed in the subfamily Ponginae with orangutans. 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. This falls within the range of P. boisei 278–378 mm2 (0.431–0.586 sq in), so the discoverers assigned it to an indeterminate species of Paranthropus rather than P. Discovered in 1938, it was among the first early hominins described, and became the type species for the genus Paranthropus. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form. Robust australopithecines—as opposed to gracile australopithecines—are characterised by heavily built skulls capable of producing high stresses and bite forces, as well as inflated cheek teeth (molars and premolars). But please. Brain hypothesised that Dinofelis and perhaps also hunting hyenas specialised on killing australopithecines,[102] but carbon isotope analysis indicates these species predominantly ate large grazers, while the leopard, the sabertoothed Megantereon, and the spotted hyena were more likely to have regularly consumed P.
