Felfedezése[ szerkesztés ] Paranthropus-leletek Afrikában a P. Abban az időben az australopithecusoknak két neme volt ismert, a Raymond Dart által felfedezett Australopithecus és a Paranthropus, amelynek akkor egyetlen képviselőjét, a P. Louis Leakey Mary férje úgy vélte, hogy a koponya mindkét nem jellegzetességeit magán hordozza, de 20 különbséget is feljegyzett és ezért Ezt követően kövekkel körbevették a fosszíliát, hogy megvédjék az időjárás viszontagságaitól, mert a feltárással meg akarták várni a fotóst.

A házaspár a Dear Boy Drága Fiú nevet adta a leletnek. Zinj a kelet-afrikai partvidék arab neve, a görög anthroposz embert jelent, Charles Watson Boise pedig óta finanszírozta Leakey ásatásait; vagyis a faj neve "Boise kelet-afrikai embere" lett.

A National Geographic szeptemberi számába is írt egy cikket a Zinjanthropusról, amelynek korát ezer évre becsülte. Leakey nem fogadte el az álláspontjukat és a huzavona még éveken át folytatódott; ezt egyes kollégáival való viszonya is megsínylette.

Leakey eredetileg úgy vélte, hogy a P. Ezt az álláspontját azonban revideálta, amikor két évvel később a felesége a nagyobb agyú Homo habilis csontjait tárta fel a közelben. Korábban a csontváz részeit csak bizonytalan besorolású állkapocstöredékekkel azonosítani, mint a KNM-ER esetében.

Az OH 80 mellett olduvai kőeszközöket is találtak. A fajok közös, monofiletikus származása azonban vitatott, egyes kutatók szerint csak hasonló testalkatú, de más eredetű fajokat raktak össze egy mesterséges, parafiletikus csoportba.

A csonzvázleletek kis száma miatt az egymás közötti és más australopithecusokkal való részletes összehasonlítás nehézségekbe ütközik.

A közös eredet legfőbb bizonyítéka a masszív állkapocs; ennek szerkezete azonban erősen függ a faj étrendjétől és környezetétől és nem zárható ki, hogy egymástól függetlenül fejlődött ilyenre a P. A monofiletikus eredet hívei szerint a P. A parafiletikusok mindhárom fajt áthelyeznék az Australopithecus nembe. Ekkor még csak az A. For example, if the South African A.

This would leave the Ethiopian A. The terms P. This is generally interpreted as having allowed P. This is typically considered to be evidence of a high bite force.

In contrast, the cheek teeth of both sexes are enormous postcanine megadontiawhich would have increased the pressure applied to food. The premolars resemble molars are molarisedwhich may indicate P. The enamel on the cheek teeth are among the thickest of any known ape, which would help resist high stresses while biting.

However, it is difficult to predict with accuracy the true dimensions of living males and females due to the lack of definitive P. Based on an approximation of Sablon:Cvt for the femur before it was broken and using modern humanlike proportions which is probably an unsafe assumptionOH 80 was about Sablon:Cvt tall in life.

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.

Unlike P. This could either indicate that P. In contrast, the P. Nonetheless, despite lacking a particularly forceful precision grip like Homo, the hand was still dextrous enough to handle and manufacture simple tools. Because of this, the predominant model of Paranthropus extinction for the latter half of the 20th century was that it was subacute thyroiditis and nodules to adapt to the volatile climate of the Pleistoceneunlike the much more adaptable Homo.

Carbon isotope analyses report a diet of predominantly C4 plants, such as low quality and abrasive grasses and sedges. A similar scheme may have been in use by P. Inbiological 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.

This could potentially indicate P. Boaz noticed that the relative proportions between large mammal families at the Shungura Formation are quite similar to the proportion in modern-day across sub-Saharan Africa.

Boaz believed that hominins would have had about the same population density as other large mammals, which would equate to 0.

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 subacute thyroiditis and nodules of 0. Martin considered population models based on the number of known specimens to be flimsy.

InMartin applied equations formulated by ecologists Alton S. Harestad and Fred L. Bunnel in to estimate the home range and population density of large mammals based on weight and diet, and, using a weight of Sablon:Cvthe got: Sablon:Cvt and 0.

Further, the size of the sagittal crest and the gluteus muscles in male western lowland gorillas has been correlated with reproductive success.

They extended their interpretation of the crest to the males of Paranthropus species, with the crest and resultantly larger head at least in P. This contrasts with other primates which flash the typically engorged canines in agonistic display the canines of Paranthropus are comparatively small. However, it is also possible that male gorillas and orangutans require larger temporalis muscles to achieve a wider gape to better display the canines.

Broadly speaking, the emergence of the first permanent molar in early hominins has been variously estimated anywhere from 2.

The tips of the mesial cusps of the 1st molar on the side closest to the premolar of KNM-ER were at about the same level as the cervix where the enamel meets the cementum of its non-permanent 2nd premolar. In baboons, this stage occurs when the 1st molar is about to erupt from the gums.

The subacute thyroiditis and nodules root is about Sablon:Cvtwhich is similar to most other hominins at this stage. In contrast, the root of the P. The specimen's 1st molar may have erupted 2—3 months before death, so possibly at 2.

In modern apes including humansdental 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. More expansive river valleys—namely the Omo River Valley—may have served as important refuges for forest-dwelling creatures.

Being cut off from the forests of Central Africa by a savanna corridor, these East African forests would have promoted high rates of endemismespecially during times of climatic volatility. This would mean that, like chimps, they often inhabited areas with an average diurnal temperature of Sablon:Cvtdropping to Sablon:Cvt at night.
