This displaced the eye sockets forward somewhat, causing a weak brow ridge and receding forehead. The first remains, a partial skull including a part of the jawbone (TM 1517), were discovered in June 1938 at Kromdraai, South Africa, by local schoolboy Gert Terblanche. Paranthropus robustus (or Australopithecus robustus) was originally discovered at Kromdraai in South Africa in 1938 by the anthropologist Robert Broom. [65] Juvenile P. robustus may have relied more on tubers than adults, given the elevated levels of strontium compared to adults in teeth from Swartkrans Cave, which, in the area, was most likely sourced from tubers. [96] About 75% of mammalian remains other than P. robustus are monkeys, including leaf-eating colobine monkeys, possibly the earliest record of the Hamadryas baboon, Gorgopithecus, and Papio angusticeps in South Africa. It is still debated if this is a valid natural grouping (monophyletic) or an invalid grouping of similar-looking hominins (paraphyletic). [9] Anthropologists Sherwood Washburn and Bruce D. Patterson were the first to recommend synonymising Paranthropus with Australopithecus in 1951, wanting to limit hominin genera to only that and Homo,[10] and it has since been debated whether or not Paranthropus is a junior synonym of Australopithecus. By analyzing the splay and orientation of fossil hominin tooth roots, researchers now suggest that Paranthropus robustus had a unique way of chewing food not seen in other hominins. In 1972, Robinson estimated Paranthropus as having been massive. It is now known that ‘robust’ refers solely to tooth and face size, not to the body size of P. robustus. 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. In 1994, Andre found the most complete skull (DNH 7; Drimolen Hominid 7) of an early human side branch in our evolution, Paranthropus robustus. [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. CC0. They found that the microwear patterns in P. robustus suggest hard food was infrequently consumed, and therefore the heavy build of the skull was only relevant when eating less desirable fallback foods. [26] In 2001, Polish anthropologist Katarzyna Kaszycka said that Broom quite often artificially inflated brain size in early hominins, and the true value was probably much lower. erectus in Swartkrans, but they estimated male H. ergaster/H. The juvenile P. robustus skullcap SK 54 has two puncture marks consistent with the lower canines of the leopard specimen SK 349 from the same deposits. Because the chewing muscles are arranged the same way, Walker postulated that the heavy build was instead an adaptation to chew a large quantity of food at the same time. [61] Since then, hominin exploitation of USOs has gained more support. The only thoracolumbar series (thoracic and lumbar series) preserved belongs to the juvenile SKW 14002, and either represents the 1st to the 4th lumbar vertebrae, or the 2nd to the 5th. [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. Isotopic evidence for dietary variability in the early hominin Paranthropus robustus. By this hypothesis, a female moving out of her birth group may have spent little time alone and transferred immediately to another established group. robustus. 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. [46] The femoral head StW 311, which either belongs to P. robustus or early Homo, seems to have habitually been placed in highly flexed positions based on the wearing patterns, which would be consistent with frequent climbing activity. Specimens include a crushed partial right face (COB 101), 3 isolated teeth, a juvenile jawbone, and several skull fragments. 4 biomass than any other hominin studied to date, including its congener Paranthropus robustus from South Africa. [7] This scheme was widely criticised for being too liberal in demarcating species. The skulls of males have a well-defined sagittal crest on the midline of the skullcap and inflated cheek bones, which likely supported massive temporal muscles important in biting. Discover (and save!) The braincase was described in the journal Science today, together with the skullcap of another ancient hominin, Paranthropus robustus, found at the same site. Robert Broom recovered the first specimen of a robust australopith in 1938 from the South African cave site of Kromdraai.He gave it the name Paranthropus robustus and noted its hominin features as well as its exaggerated chewing apparatus. Hominiden (oermensen): De Australopithecus- Paranthropus. We don’t know everything about our early ancestors—but we keep learning more! Homo possibly was able to survive by inhabiting a much larger geographical range, more likely to find a suitable refuge area during unfavourable climate swings. [54], In 2001, palaeoanthropologist Randall L. Susman and colleagues, using two recently discovered proximal femoral fragments from Swartkrans, estimated an average of 42 kg (93 lb) for males and 30 kg (66 lb) for females. However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus. 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. Paranthropus boisei or Australopithecus boisei was an early hominin, described as the largest of the Paranthropus genus (robust australopithecines). When scientist Robert Broom bought a fossil jaw fragment and molar in 1938 that didn’t look anything like some of the Au. These could indicate a decreased climbing capacity compared to non-human apes[43] and P. Proponents of paraphyly allocate these three species to the genus Australopithecus as A. boisei, A. aethiopicus, and A. [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. Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei. Unlike other apes and gracile australopithecines, but like humans, the premaxillary suture between the premaxilla and the maxilla (on the palate) formed early in development. boisei). [58] In 1981, English anthropologist Alan Walker, while studying the P. boisei skulls KNM-ER 406 and 729, pointed out that bite force is a measure of not only the total pressure exerted but also the surface area of the tooth over which the pressure is being exerted, and Paranthropus teeth are 4–5 times the size of modern human teeth. [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). [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).

Paranthropus robustus Record ID dpo_3d_200072 Metadata Usage Usage Conditions Apply. In contrast, those of other hominins reach 5–6 mm (0.20–0.24 in) after the tooth has emerged not only from the gums (a later stage of dental development). The first hominin specimen (G14018) was found by German palaeontologist Elisabeth Vrba in 1979, and the other two specimens were recovered in 1997 by respectively South African palaeoanthropologist Andre Keyser and excavator L. Dihasu. [69], However, in 2011, palaeoanthropologist Sandi Copeland and colleagues studied the strontium isotope ratio of P. robustus teeth from the dolomite Sterkfontein Valley, and found that like other hominins, but unlike other great apes, P. robustus females were more likely to leave their place of birth (patrilocal). This could potentially indicate the lower limbs had a wider range of motion than those of modern humans. [71], In 1988, Brain and South African archaeologist A. Sillent analysed the 59,488 bone fragments from Swartkrans Member 3, and found that 270 had been burnt, mainly belonging to medium-sized antelope, but also zebra, warthog, baboon, and P. robustus. However, laser ablation stable isotope analysis reveals that the δ13C values of Paranthropus robustus individuals often changed seasonally and interannually. [96] Using this and palaeomagnetism, it may date to roughly 1.8 million years ago. The latter is most likely, and the exposed root seems to have caused hypercementosis to anchor the tooth in place. What can lice tell us about human evolution? [94], At Swartkrans, P. robustus has been identified from Members 1–3. 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. He also noted that, compared to other australopithecines, Paranthropus seems to have had an expanded cerebellum like Homo, echoing what Tobias said while studying P. boisei skulls in 1967. The distal phalanges seem to be essentially humanlike. P. robustus may have had a genetic susceptibility for pitting enamel hypoplasia on the teeth, and seems to have had a dental cavity rate similar to non-agricultural modern humans. [23] The enamel thickness on the cheek teeth is relatively on par with that of modern humans, though australopithecine cheek tooth enamel thickens especially at the tips of the cusps, whereas in humans it thickens at the base of the cusps. [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. [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. [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. They were found across the entire depth of Member 3, so fire was a regular event throughout its deposition. Because both P. robustus and H. ergaster/H. 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. 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. 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. See more ideas about hominid, human evolution, southern africa. Paranthropus robustus is a small-brained extinct hominin that lived between 2 million and 1.2 million years ago in what is now South Africa. According to EurekAlert!, researchers have known for some time that the rise of Paranthropus robustus “roughly coincided” with the disappearance of the more primitive Australopithecus species. Particularly regarding cranial features, the development of P. robustus seemed to be in the direction of a "heavy-chewing complex". robustus. Eventually, scientists recognized that the 'robust' forms were different enough to be in their own species, originally called Australopithecus robustus. [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). A total of 31 specimens representing at least 17 individuals have been recovered. This jaw bone was then sent to Robert Broom. All these species dated to the Pleistocene and were found in the same general vicinity (now called the "Cradle of Humankind"). Feb 2, 2016 - (2.3 to 1.2 mya). erectus skull KNM ER 3733 (which is considered a human ancestor). P. robustus and H. habilis may have achieved about the same grade of bipedality. Paranthropus robustus had relatively large teeth and a small brain. 1. Bone tools may have been used to cut or process vegetation,[71] process fruits (namely marula fruit), strip tree bark,[72] or dig up tubers or termites. DNH 7 was discovered by A. Keyser's team in 1994 at the Drimolen site in South Africa. The braincase was described in the journal Science today, together with the skullcap of another ancient hominin, Paranthropus robustus, found at the same site. [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. [25] The animal assemblage is broadly similar to that of Cooper's Cave, meaning they probably are about the same age. Discovered in 1938, it was among the first early hominins described, and became the type species for the genus Paranthropus. Paranthropus robustus definition, an extinct species of large-toothed bipedal hominin, formerly named Australopithecus robustus, that lived in southern Africa about 1.5–2 million years ago. Paleoanthropologists are constantly in the field, excavating new areas with groundbreaking technology, and continually filling in some of the gaps about our understanding of human evolution. These tools were all found alongside Acheulean stone tools, except for those from Swartkrans Member 1 which bore Oldowan stone tools. A probable genetic origin for pitting enamel hypoplasia on the molars of Paranthropus robustus. The researchers argue that the DNH 155 specimen they found provides the first high resolution evidence for microevolution within an early hominin species. [6] At this point in time, humans and allies were classified into the family Hominidae, and non-human great apes into "Pongidae"; in 1950, Broom suggested separating early hominins into the subfamilies Australopithecinae (Au. [39] The pelvis seems to indicate a more-or-less humanlike hip joint consistent with bipedalism, though differences in overall pelvic anatomy may indicate P. robustus used different muscles to generate force and perhaps had a different mechanism to direct force up the spine. Conversely, SK 3981 is more similar to those of healthy humans, which could be explained as: SK 3981 is abnormal, the vertebrae took on a more humanlike condition with maturity, or one of these specimens is assigned to the wrong species. Carbon isotope studies of P. robustus from South Africa indicated that it con- sumed some plants using C4photosynthesis such as tropical grasses or sedges, but were also consistent with most of its dietary carbon (approximately 70%) having been derived from the C3 [87], P. robustus seems to have had notably high rates of pitting enamel hypoplasia (PEH), where tooth enamel formation is spotty instead of mostly uniform. [23] The well-defined sagittal crest and inflated cheeks are absent in the presumed-female skull DNH-7, so Keyser suggested that male P. robustus may have been more heavily built than females (P. robustus was sexually dimorphic). The anatomy of the sacrum and the first lumbar vertebra (at least the vertebral arch), preserved in DNH 43, are similar to those of other australopithecines. Based on 4 specimens, males averaged 40 kg (88 lb) in weight and females 30 kg (66 lb). [5], In 1939, Broom hypothesised that P. robustus was closely related to the similarly large-toothed ape Gigantopithecus from Asia (extinct apes were primarily known from Asia at the time) believing Gigantopithecus to have been a hominin. [88], As many as four P. robustus individuals have been identified as having had dental cavities, indicating a rate similar to non-agricultural modern humans (1–5%). [22] The site is thought to be roughly 2–1.5 million years old based on animal remains which have also been recovered from Swartkrans Member 1. Familia: Hominidae Subfamilia: Homininae Tribus: Hominini Subtribus: Hominina Genus: †Praeanthropus Species: Praeanthropus robustus Name []. [71] The animal remains of Kromdraai A suggest deposition occurred anywhere between 1.89 and 1.63 million years ago, and the presence of Oldowan or Achulean tools indicates early Homo activity. The brows of the former also are rounded off rather than squared, and the sagittal crest of the presumed-male DNH 155 is more posteriorly (towards the back of the head) positioned. 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). Sep 3, 2019 - Paranthropus robustus (or Australopithecus robustus) is an early hominin, originally discovered in Southern Africa in 1938. He also found that microwearing on 20 P. boisei molar specimens were indistinguishable from patterning recorded in mandrills, chimps, and orangutans. The presence of the Hamadryas baboon and Dinopithecus could mean Members 1–3 were deposited 1.9–1.65 million years ago, though the presence of warthogs suggests some sections of the deposits could date to after 1.5 million years ago. Using these, he argued these hominins had a humanlike prolonged childhood. [78], Females may have reached skeletal maturity by the time the third molar erupted, but males appear to have continued growing after reaching dental maturity, during which time they become markedly more robust than females (sexual bimaturism). These roughly aligned with other australopithecines and chimps. OpenUrl Abstract / FREE Full Text [73][72][71] The form of P. robustus incisors appears to be intermediate between H. erectus and modern humans, which could possibly mean it did not have to regularly bite off mouthfuls of a large food item due to preparation with simple tools. A suite of different dating techniques all hinted that the two species’ braincases were more or less the same age—about two million years old. Like humans, the finger bones are uncurved and have weaker muscle attachment than non-human apes, though the proximal phalanges are smaller than in humans. [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. [49], Broom had noted that the ankle bone and humerus of the holotype TM 1517 were about the same dimensions as that of a modern San woman, and so assumed humanlike proportions in P. robustus. Based on just these three, he reported an average height of 132 cm (4 ft 4 in) for P. robustus males and 110 cm (3 ft 7 in) for females. Female P. robustus were about the same estimated weight as female H. ergaster/H. transvaalensis"), "Paranthropinae" (Pa. robustus and "Pa. crassidens"), and "Archanthropinae" ("Au. The 1st permanent molar of SK 63, which may have died at 3.4–3.7 years of age, possibly erupted at 2.9–3.2 years. [56] In 2015, biological anthropologist Mark Grabowski and colleagues, using 9 specimens, estimated an average of 32.3 kg (71 lb) for males and 24 kg (53 lb) for females. Paranthropus robustus was a large-toothed, small-brained hominin that co-existed with our early direct human ancestors as a ‘cousin species’. [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. [70], Cave sites in the Cradle of Humankind often have stone and bone tools, with the former attributed to early Homo and the latter generally to P. robustus, as bone tools are most abundant when P. robustus remains far outnumber Homo remains. At Members 1 and 2, about 35% of the P. robustus leg or foot specimens were the same size as those in a 28 kg (62 lb) human, 22% in a 43 kg (95 lb) human, and the remaining 43% bigger than the former but less than a 54 kg (119 lb) human except for KNM‐ER 1464 (an ankle bone). They concluded that these bones were, "the earliest direct evidence of fire use in the fossil record," and compared the temperatures with those achieved by experimental campfires burning white stinkwood which commonly grows near the cave. Paranthropus robustus (or Australopithecus robustus) was originally discovered at Kromdraai in South Africa in 1938 by the anthropologist Robert Broom. Scott, R.S., Ungar, P.S., Bergstrom, T.S., Brown, C.A., Grine, F.E., Teaford, M.F., Walker, A., 2005. In order for cavity-creating bacteria to reach this area, the individual would have also presented either alveolar resportion, which is commonly associated with gum disease; or super-eruption of the tooth which occurs when it becomes worn down and has to erupt a bit more in order to maintain a proper bite, exposing the root in the process. [11] By the 21st century, "P. crassidens" had more or less fallen out of use in favour of P. robustus. [50] Similarly, in 1988, American anthropologist Henry McHenry reported much lighter weights as well as notable sexual dimorphism for Paranthropus. Sep 7, 2014 - This Pin was discovered by Sinan Onsun. Subsequent researchers reinforced this model studying the musculature of the face, dental wearing patterns, and primate ecology. africanus. [48] The big toe bone of P. robustus is not dextrous, which indicates a humanlike foot posture and range of motion, but the more distal ankle joint would have inhibited the modern human toe-off gait cycle. Based on 3 specimens, males may have been 132 cm (4 ft 4 in) tall and females 110 cm (3 ft 7 in). Between 1948 and 1952, similar fossils were unearthed from Swartkrans, South Africa, which proved to be another of the richest sources of early … For comparison, chimp jaws are generally depository reflecting prognathism, and modern humans resorptive reflecting a flat face. These bones are no longer considered to have been tools, and the existence of this culture is not supported. 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. robustus. This discounts the plausibility of a harem society, which would have resulted in a matrilocal society due to heightened male–male competition. [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. [82] In 1972, after estimating a foetal size of 1,230–1,390 g (2.7–3.1 lb) based on an adult female weight of 50 kg (110 lb), anthropologist Walter Leutenegger estimated foetal head size at about 110–160 cc (6.7–9.8 cu in), similar to a chimp. Paranthropus robustus (or Australopithecus robustus) is an early hominin, originally discovered in Southern Africa in 1938. 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. Sahelanthropus tchadensis is an extinct homininae species that is dated to about 7 million years ago, during the Miocene epoch, possibly very close to the time of the chimpanzee–human divergence. The only potential Homo specimen from Member 3 is KB 5223, but its classification is debated. 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. 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. A fossil skull has a flat face, large molars, and a prominent sagittal crest, suggesting it is _____. They stated overall brain anatomy of P. robustus was more like that of non-human apes. erectus skull DNH 134. McHenry plotted body size vs. the cross sectional area of the femoral head for a sample of just humans and a sample with all great apes including humans, and calculated linear regressions for each one. KB 6067, therefore, may possibly be basal to (more ancient than) other P. robustus specimens, at least those for which ear morphology is known. Political Events. [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. This is odd as P. robustus is thought to have had a diet high in gritty foods, and gritty foods should decrease cavity incidence rate, so P. robustus may have often consumed high-sugar cavity-causing foods. Thus, there are 108 bone tool specimens from the region in total, and possibly an additional two from Kromdraai B. 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). The brain volume of the specimen SK 1585 is estimated to have been 476 cc, and of DNH 155 about 450 cc (for comparison, the brain volume of contemporary Homo varied from 500–900 cc). The holotype specimen, OH 5, was discovered by palaeoanthropologist Mary Leakey in 1959, and described by her husband Louis a month later. INTRODUCTION.
