Where Lived: Eastern Africa (Ethiopia, Kenya, Tanzania, Malawi) When Lived: About 2.3 to 1.2 million years ago Paranthropus boisei lived about 2.3 to 1.2 million years ago. In the first course that I took in physical anthropology, I was most fascinated by the Paranthropus boisei face from Olduvai Gorge (see Figures 18.1 and 18.5) and the Natron/Peninj mandible from the Peninj site near Lake Natron. habilis. This is generally interpreted as having allowed P. boisei to resist high stresses while chewing,[19] though the thick palate could instead be a byproduct of facial lengthening. Constantino, P., Wood, B., 2007. [4], By the time OH 5 was discovered, the Leakey's had spent 24 years excavating the area for early hominin remains, but had instead recovered mainly other animal remains as well as the Oldowan stone tool industry. In contrast, the P. robustus hand is not consistent with climbing. [13] Now, the earliest known South African australopithecine ("Little Foot") dates to 3.67 million years ago, contemporaneous with A. Unlike P. robustus, the arm bones of OH 80 are heavily built, and the elbow joint shows similarities to that of modern gibbons and orangutans. This is typically considered to be evidence of a high bite force. In 2005, biological anthropologists Greg Laden and Richard Wrangham proposed that Paranthropus relied on USOs as a fallback or possibly primary food source, and noted that there may be a correlation between high USO abundance and hominin occupation. Being cut off from the forests of Central Africa by a savanna corridor, these East African forests would have promoted high rates of endemism, especially during times of climatic volatility. [14], Such arguments are based on how one draws the hominin family tree, and the exact classification of Australopithecus species with each other is quite contentious. The tooth root is about 5 mm (0.20 in), which is similar to most other hominins at this stage. Category: Paranthropus boisei . This could potentially indicate P. boisei was manufacturing the Oldowan tradition and ate meat to some degree. They were somewhat more encephalized than past species, with a cranial capacity of 514 cc (range = 494–537 cc). Below are some of the still unanswered questions about P. boisei that may be answered with future discoveries: Leakey, L.S.B., 1959. Paleoanthropologists actually found the first fossils belonging to P. boisei in 1955, but it wasn’t until Mary Leakey’s 1959 discovery of the ‘Zinj’ skull (OH 5) that scientists knew what they had found was a new species. PLoS One 3, e2044. 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. [49] Other likely Oldowan predators of great apes include the hunting hyaena Chasmaporthetes nitidula, the sabertoothed cats Dinofelis and Megantereon,[50] and the crocodile Crocodylus anthropophagus. Cranial capacity ranges from 280 to 450 cc in adult chimpanzees, and from 350 to 750 cc in adult gorillas ( Schultz 1965 ). [39], P. boisei coexisted with H. habilis, H. rudolfensis, and H. ergaster / H. erectus, but it is unclear how they interacted. However, it is much debated whether or not Paranthropus is an invalid grouping and is synonymous with Australopithecus, so the species is also often classified as Australopithecus aethiopicus. They were somewhat more encephalized than past species, with a cranial capacity of 514 cc (range = 494–537 cc). (book by Richard Potts and Chris Sloan), What was the advantage of the big jaws and teeth of, These early humans flourished for a million years, over four times as long as our own species. OH 80 was also associated with Oldowan stone tools. [41], A 2017 study postulated that, because male non-human great apes have a larger sagittal crest than females (particularly gorillas and orangutans), the crest may be influenced by sexual selection in addition to supporting chewing muscles. P. boisei is the most robust of the robust australopithecines, whereas the South African P. robustus is smaller with comparatively more gracile features. [40] Biologist Robert A. Martin considered population models based on the number of known specimens to be flimsy. [1] On July 17, 1959, palaeoanthropologist Mary Leakey discovered a skull without a jaw, OH 5. However, they still retained Zinjanthropus and recommended demoting it to subgenus level as Australopithecus (Zinjanthropus) boisei, considering Paranthropus to be synonymous with Australopithecus. Paranthropus boisei (kako je ta vrsta kasnije kategorizirana) pokazala se kao pravo blago, naročito kada je sin spomenutih antropologa, Richard Leakey, ustvrdio da je to bila prva vrsta hominina koja je koristila kamene alate. The premolars resemble molars (are molarised), which may indicate P. boisei required an extended chewing surface for processing a lot of food at the same time. This skull has a cranial capacity of 500 cubic centimeters, nearly identical to the 510 cubic centimeters of presumed male P. boisei KNM-ER 406. P. boisei was originally believed to have been a specialist of hard foods, such as nuts, due to its heavily built skull, but it was more likely a generalist feeder of predominantly abrasive C4 plants, such as grasses or underground storage organs. The first remains—Olduvai Hominin (OH) 3, a baby canine and large molar tooth—were unearthed in 1955 in Olduvai Gorge, Tanzania. The holotype specimen, OH 5, was discovered by palaeoanthropologist Mary Leakey in 1959, and described by her husband Louis a month later. This contrasts with other primates which flash the typically engorged canines in agonistic display (the canines of Paranthropus are comparatively small). Important fossil discoveries. The incisors and canines are reduced, which would hinder biting off chunks of large food pieces. KNM-ER 406 is a nearly complete adult male Paranthropus boisei.It has the facial and cranial features typical of the species such as massive cheek teeth, and the widely flaring zygomatic arches with a forward placed connection to the other facial bones, and large cheek bones supported powerful chewing muscles - the latter two features giving it a "dish-shaped" face. “Paranthropus boisei” by Lillyundfreya is licensed under CC BY-SA 3.0.

[6]:108–109 In 1997, the first specimen with both the skull and jawbone (and also one of the largest specimens), KGA10-525, was discovered in Konso. Approaching the Science of Human Origins from Religious Perspectives, Religious Perspectives on the Science of Human Origins, Submit Your Response to "What Does It Mean To Be Human? The 1975 discovery of P. boisei specimen KNM-ER 406 and H. erectus specimen KNM-ER 3733 in the same stratigraphic layer was the first example of species coexistence. P. boisei mainly inhabited wet, wooded environments, and coexisted with H. habilis, H. rudolfensis, H. ergaster, and H. erectus. [19] In the upper jaw, the 1st molar averages roughly 250 mm2 (0.39 sq in), the 2nd molar 320 mm2 (0.50 sq in), and the 3rd molar 315 mm2 (0.488 sq in); in the lower jaw, the 1st molar averages roughly 260 mm2 (0.40 sq in), the 2nd molar 315 mm2 (0.488 sq in), and the 3rd molar 340 mm2 (0.53 sq in). 15th January 2019. This … This is generally interpreted as having allowed P. boisei to resist high stresses while chewing, though the thick palate could instead be a bypro… The genus name derives from the medieval term for East Africa, "Zanj", and the specific name was in honour of Charles Watson Boise, the Leakeys' benefactor. Broadly speaking, the emergence of the first permanent molar in early hominins has been variously estimated anywhere from 2.5 to 4.5 years of age, which all contrast markedly with the modern human average of 5.8 years. Paranthropus boisei was discovered by Mary Leakey in 1959 at Olduvai Gorge in Tanzania (specimen OH5). KNM-ER 732, a partial cranium of a female Paranthropus boisei has many characteristic P. boisei features. Follow: Latest/popular posts. Cranial capacity in this species suggests a slight rise in brain size (about 100 cc in 1 million years) independent of brain enlargement in the genus Homo. [16] It is possible that P. aethiopicus evolved even earlier, up to 3.3 mya, on the expansive Kenyan floodplains of the time. [28] The femoral head, the best proxy for estimating body mass, is missing, but using the shaft, OH 80 weighed about 50 kg (110 lb) assuming humanlike proportions, and 61.7 kg (136 lb) using the proportions of a non-human ape. Robust australopithecines are characterised by heavily built skulls capable of producing high stresses and bite forces, and some of the largest molars with the thickest enamel of any known ape. See also. [17] The oldest P. boisei remains date to about 2.3 mya from Malema. In contrast, the root of the P. robustus specimen SK 62 was 6 mm (0.24 in) when emerging through the dental alveolus (an earlier stage of development than gum emergence), so, unless either specimen is abnormal, P. robustus may have had a higher tooth root formation rate. Chickens, chimpanzees, and you - what do they have in common? Human evolution - Human evolution - Increasing brain size: Because more complete fossil heads than hands are available, it is easier to model increased brain size in parallel with the rich record of artifacts from the Paleolithic Period (c. 3.3 million to 10,000 years ago), popularly known as the Old Stone Age. The P. boisei skull is heavily built, and features a defined brow ridge, receding forehead, rounded bottom margins of the eye sockets, inflated and concave cheek bones, a thick palate, and a robust and deep jawbone. robustus. Why didn't the Leakey's think that Paranthropus boisei was the stone tool marker at Olduvai? A new fossil from Olduvai. But dental microwear patterns seen on P. boisei teeth are more similar to living fruit-eaters with fine striations, rather than large, deep pits seen in the teeth of living species that eat grass, tough leaves and stems, or other hard, brittle foods. The force was focused on the large cheek teeth (molars and premolars). More finds have confirmed that this species was one of the most prevalent in Eastern Africa during the time period when early members of the genus Homo were also present. Boaz believed that hominins would have had about the same population density as other large mammals, which would equate to 0.006–1.7 individuals per square kilometre (0.4 square miles). Earliest known common genetic condition. What can lice tell us about human evolution? [25] In 1983, French anthropologist Roger Saban stated that the parietal branch of the middle meningeal artery originated from the posterior branch in P. boisei and P. robustus instead of the anterior branch as in earlier hominins, and considered this a derived characteristic due to increased brain capacity. [31] The microwearing on P. boisei molars is different than that on P. robustus molars, and indicates that P. boisei, unlike P. robustus, very rarely ever ate hard foods. [30], However, in 1981, English anthropologist Alan Walker found that the microwearing patterns on the molars were inconsistent with a diet high in hard foods, and were effectively indistinguishable from the pattern seen in the molars of fruit-eating (frugivorous) mandrills, chimps, and orangutans. Alternatively, by multiplying the density of either bovids, elephants, or hippos by the percentage of hominin remains out of total mammal remains found at the formation, Boaz estimated a density of 0.001–2.58 individuals per square kilometre. Paranthropus walkeri lived between 2.3 and 2.7 million years ago. [6]:109 The first definitive bodily elements of P. boisei associated with facial elements, OH 80 (isolated teeth with an arm and a leg), were discovered in 2013. Paranthropus boisei, arguably the best known of the “robust australopithecines,” (the species included in the genus Paranthropus—Paranthropus aethiopicus, Paranthropus robustus, and Paranthropus boisei) is known from East African sites dating between 2.4 and 1.4 million years ago. [26] It has since been demonstrated that the parietal branch could originate from either the anterior or posterior branches, sometimes both in a single specimen on opposite sides of the skull as in KNM-ER 23000 and OH 5. [2] Soon after OH 5's discovery, Louis presented "Z. boisei" to the 4th Pan-African Congress on Prehistory in Kinshasa, Democratic Republic of the Congo. However, it is difficult to predict with accuracy the true dimensions of living males and females due to the lack of definitive P. boisei skeletal remains, save for the presumed male OH 80. Paranthropus boisei / Australopithecus boisei, KNM-ER 406, L7a-125, 1 700 000 BP. [27], The wide range of size variation in skull specimens seems to indicate a great degree of sexual dimorphism with males being notably bigger than females. In 1988, Falk and Tobias demonstrated that hominins can have both an occipital/marginal and transverse/sigmoid systems concurrently or on opposite halves of the skull, such as with the P. boisei specimen KNM-ER 23000. [45] Australopithecines and early Homo likely preferred cooler conditions than later Homo, as there are no australopithecine sites that were below 1,000 m (3,300 ft) in elevation at the time of deposition. [35] In this model, P. boisei may have been a generalist feeder with a predilection for USOs,[37][34] and may have gone extinct due to an aridity trend and a resultant decline in USOs in tandem with increasing competition with baboons and Homo. The enormous cheek teeth (postcanine megadontia) of both sexes would have increased the pressure applied to food. It was originally placed into its own genus as "Zinjanthropus boisei", but is now relegated to Paranthropus along with other robust australopithecines. This species was nicknamed Nutcracker Man for its big teeth and strong chewing muscles, which attached to the large crest on the skull. Carbon isotope analyses report a diet of predominantly C4 plants, such as low quality and abrasive grasses and sedges. ‘Zinj’ became the type specimen for P. boisei and, soon after, arguably the most famous early human fossil from Olduvai Gorge in northern Tanzania. This species had even larger cheek teeth than P. robustus,a flatter, bigger-brained skull than P. aethiopicus, and the thickest dental enamel of any known early human. [22] However, the lower-end specimen, Omo L338‐y6, is a juvenile, and many skull specimens have a highly damaged or missing frontal bone which can alter brain volume estimates. Estimated Weight: 70 kg [19] 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. The cranial capacity of this skull has been estimated at 510 cubic centimeters. Dimensions: height - 120 - 140 сm, weight - 35 - 50 kg. 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. ", "Shaping Humanity: How Science, Art, and Imagination Help Us Understand Our Origins" (book by John Gurche), What Does It Mean To Be Human? Their faces, jaws, and cheek teeth were massive and truly unforgettable. I still remember the first time I saw them, and the species has always been for me one of the more interesting discoveries in paleoanthropology. [6]:106–107, P. aethiopicus is the earliest member of the genus, with the oldest remains, from the Ethiopian Omo Kibish Formation, dated to 2.6 million years ago (mya) at the end of the Pliocene. The environment P. boisei lived in was mainly grasslands, but could have also been less open with rivers and lakes scattered throughout. It is widely accepted that P. boisei’s ancestor is A. africanus. boisei. [35], 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. [6]:120 The P. boisei skull is heavily built, and features a defined brow ridge, receding forehead, rounded bottom margins of the eye sockets, inflated and concave cheek bones, a thick palate, and a robust and deep jawbone. [1] Synonymising Paranthropus with Australopithecus was first suggested by anthropologists Sherwood Washburn and Bruce D. Patterson in 1951, who recommended limiting hominin genera to only Australopithecus and Homo. The species was originally named Zinjanthropus boisei by the Leakeys, apparently ignoring Dr. Robert Broom's original Paranthropus name, later assigned to the Australopithecus genus which was then split as described above. Cranial Capacity: 530 cc. ER 406 ER 406 was found by R. Leakey and H. Mutua in 1970 at Koobi Fora, Kenya. But these early humans were also able to crush and grind tough plant foods during difficult times. Cranial Capacity: 530 cc. [2] The remains were clearly australopithecine (not the genus Homo), and at the time, the only australopithecine genera described were Australopithecus by Raymond Dart and Paranthropus (the South African P. robustus) by Robert Broom, and there were arguments that Paranthropus was synonymous with Australopithecus. [47] However, when describing P. boisei 5 years earlier, he said, "There is no reason whatever, in this case, to believe that the skull [OH 5] represents the victim of a cannibalistic feast by some hypothetical more advanced type of man. This would leave the Ethiopian A. garhi as the ancestor of P. aethiopicus instead of A. africanus (assuming Paranthropus is monophyletic, and that P. aethiopicus evolved at a time in East Africa when only A. garhi existed there). It's possible that this species only ate hard or tough foods during times when its preferred resources were scarce, relying on them as fallback foods. Along with the strong muscles P. boisei had some of the thickest enamel seen in most pre-modern humans. Based on an approximation of 400 mm (1.3 ft) for the femur before it was broken and using modern humanlike proportions (which is probably an unsafe assumption), OH 80 was about 156.3 cm (5 ft 2 in) tall in life. This discovery cleared up a long time controversy and confirmed that more than one species of early humans lived in the same geographical area at the same time. In 1975, the P. boisei skull KNM-ER 406 was demonstrated to have been contemporaneous with the H. ergaster skull KNM ER 3733, which is generally taken to show that Paranthropus was a sister taxon to Homo, both developing from some Australopithecus species, which at the time only included A. africanus. [1] To explain why P. boisei was associated with Oldowan tools despite not being the tool maker, Louis Leakey and colleagues, when describing H. habilis in 1964, suggested that one possibility was P. boisei was killed by H. habilis,[46] perhaps as food. [38] Like modern forest chimps and baboons, australopithecines likely foraged for food in the cooler morning and evening instead of in the heat of the day. P. boisei is the most robust of this group. It is debated if Paranthropus is a valid natural grouping (monophyletic) or an invalid grouping of similar-looking hominins (paraphyletic). 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. Compared to other robust species, P. boisei has a larger cranial capacity (500-550 cc), a more vertically set face, and a sagittal crest on the mid-brain case, as opposed to the posterior. Brain size was about 450–550 cc (27–34 cu in), similar to other australopithecines.

Also known as Australopithecus boisei Sites: East Africa: Rift Valley sites such as Turkana and Olduvai Gorge Age: 2.3 to 1.0 mya Type specimen: Zinjanthropus (Olduvai Gorge) Specimens: ER 1470, 1813, 1500, Omo L 323, OH5, Omo L. 7a-125 Cranial capacity: 510 cm3 Cranial architecture: Flared zygomatic arches to accommodate large temporal and massester muscles. The terms P. boisei sensu lato ("in the broad sense") and P. boisei sensu stricto ("in the strict sense") can be used to respectively include and exclude P. aethiopicus from P. boisei when discussing the lineage as a whole. A strong sagittal crest on the midline of the top of the skull anchored the temporalis muscles (large chewing muscles) from the top and side of the braincase to the lower jaw, and thus moved the massive jaw up and down. [6]:107[7][8] Especially from 1966 to 1975, several more specimens revealing facial elements were reported from the Shungura Formation, Ethiopia; Koobi Fora and Chesowanja, Kenya; and Omo and Konso, Ethiopia. Genus Paranthropus is subdivided further into Paranthropus aethiopicus, Paranthropus robustus and Paranthropus boisei.The remains of Paranthropus were found in Omo river valley in Southern Ethiopia and western shore of Lake Turkana in Northern Kenya.Paranthropus lived in both southern and eastern Africa was associated with stone tool making. [1] Because OH 5 was associated with the tools and processed animal bones, they presumed it to have been the toolmaker. 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. Some skulls are markedly smaller than others, which is taken as evidence of sexual dimorphism where females are much smaller than males, though body size is difficult to estimate given only one specimen, OH 80, definitely provides any bodily elements. Adult male with an estimated cranial capacity of 510 cc, from Koobi Fora, Kenya, Omo, Ethiopia (note that this valuable facsimile includes the mandible, which is not present on other facsimiles of this particular find, shown further down this page. Flaring cheekbones gave P. boisei a very wide and dish-shaped face, creating a larger opening for bigger jaw muscles to pass through and support massive cheek teeth four times the size of a modern human’s. [1] In 1960, American anthropologist John Talbot Robinson pointed out that the supposed differences are due to OH 5 being slightly larger than P. robustus, and so recommended the species be reclassified as P. boisei. Paleoanthropologists are constantly in the field, excavating new areas, using groundbreaking technology, and continually filling in some of the gaps about our understanding of human evolution. In 1981, Martin applied equations formulated by ecologists Alton S. Harestad and Fred L. Bunnel in 1979 to estimate the home range and population density of large mammals based on weight and diet, and, using a weight of 52.4 kg (116 lb), he got: 130 ha (320 acres) and 0.769 individuals per square kilometre if herbivorous; 1,295 ha (3,200 acres) and 0.077 individuals if omnivorous; and 287,819 ha (711,220 acres) and 0.0004 individuals if carnivorous. What characteristics define the genus Homo? Molar characteristics from the more recent material from the Drimolen site are thought to be intermediate between the Swartkrans and Kromdraai molars, and most researchers now … Proponents of paraphyly allocate these three species to the genus Australopithecus as A. boisei, A. aethiopicus, and A. [23] The brain volume of australopithecines generally ranged from 400–500 cc (24–31 cu in), and for contemporary Homo 500–900 cc (31–55 cu in). 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. Fossil material attributed to this hominid — one of the robust australopithecines — range from about 2.4 to 2.7 million years in age. In 1938, Robert Broom discovered the first Paranthropus robustus material at the site of Swartkrans, South Africa. This species lived in environments that were dominated by grasslands but also included more closed, wet habitats associated with rivers and lakes. [16] The youngest record of P. boisei comes Olduvai Gorge (OH 80) about 1.34 mya;[10] however, due a large gap in the hominin fossil record, P. boisei may have persisted until 1 mya. They 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. [10] The ambiguously attributed, presumed female femur KNM-ER 1500 is estimated to have been of an individual about 124 cm (4 ft 1 in) tall[29] which would be consistent with the argument of sexual dimorphism,[10] but if the specimen does indeed belong to P. boisei, it would show a limb anatomy quite similar to that of the contemporary H. Most notable is the forward placed root of the zygomatic arch, resulting in a wide flat face. More expansive river valleys–namely the Omo River Valley–may have served as important refuges for forest-dwelling creatures. [15], Because P. boisei and P. aethiopicus are both known from East Africa and P. aethiopicus is only confidently identified from the skull KNM WT 17000 and a few jaws and isolated teeth, it is debated if P. aethiopicus should be subsumed under P. boisei or if the differences stemming from archaicness justifies species distinction. This species had even larger cheek teeth than P. robustus, a flatter, bigger-brained skull than P. aethiopicus, and the thickest dental enamel of any known early human. Nonetheless, the intertrochanteric line is much more defined in OH 80, the gluteal tuberosity is more towards the midline of the femur, and the mid-shaft in side-view is straighter, which likely reflect some difference in load-bearing capabilities of the leg. The enamel on the cheek teeth are among the thickest of any known ape, which would help resist high stresses while biting.
