The scientists say the way its teeth were organised in the jaw meant it could focus its bite into a small area - the fang tip - with the incredible pressure of nearly 150 million Pascals (22,000lbs per sq inch). (bbc.co.uk)
in fact, even fossil hominins with the largest teeth and jaws probably shared this genetic change with us. (johnhawks.net)
In the last sentence of their discussion, Stedman and colleagues advanced a provocative hypothesis: Not only did Homo have smaller jaws and teeth, but reducing the jaw muscles may have enabled the evolution of larger brain size. (johnhawks.net)

Canis2
The highest values of bite force belonged to Canis lupus (830.51 Pa), L. pictus (719.03 Pa) and Ca. rufus (530.52 Pa) and the smallest values belong to Urocyon littoralis (98.14 Pa), Vulpes macrotis (92.53 Pa) and V. zerda (72.6 Pa). (researchgate.net)
According to a 2005 review of biting mammals , the gray wolf ( Canis lupus ) has the strongest bite of any canine, at 593 Newtons. (yahoo.com)
Muscles9
Other primates express this gene in their jaw muscles, where it strengthens the bite force. (johnhawks.net)
The change in jaw muscles happened long before our genus arose. (johnhawks.net)
In most vertebrates this protein is expressed in muscles that develop from the first pharyngeal arch, including temporalis , which in mammals is the largest muscle of the jaw. (johnhawks.net)
Comparison of hominin crania in superior view, to show the extent of jaw muscles. (johnhawks.net)
Australopithecus and Paranthropus have larger jaw muscles than early Homo species like H. habilis and H. erectus . (johnhawks.net)
To these researchers, the estimate held meaning because of its correspondence with early evidence of fossil Homo, which had smaller jaw muscles than earlier hominins. (johnhawks.net)
Some animals are too rare or dangerous for this type of invasive testing, so scientists have come up with another method: computerized models of an animal's skull and jaw muscles that estimate its bite force. (yahoo.com)
Hartstone-Rose explained that "the strength of the jaguar's bite is due to the arrangement of its jaw muscles, which, relative to weight, are slightly stronger than those of other cats. (yahoo.com)
The chewing muscles are not strong enough to transfer a strong enough force to the tip of the mandibles to generate a strong bite force. (whatsthatbug.com)
Newtons3
An increase in applied bite force causes a decrease in electronic resistance, which is correlated with bite force in Newtons. (allenpress.com)
The extinct creature, Dunkleosteus terrelli , could bring its jaws together with a remarkable force of 5,000 Newtons (1,100lbs-force). (bbc.co.uk)
but a modern spotted hyena, by comparison, exerts a force of only 2,000 Newtons (500lbs-force) when it cracks bones in its mouth. (bbc.co.uk)
Bite force is the pressure an animal exerts when it bites down, and the SI unit for bite force is the Newton, or kilogram-meters per second squared. (yahoo.com)
Spotted hyena1
The spotted hyena ( Crocuta crocuta ) has a bite force of 773 N - more powerful than a bear, according to this review of mammal bites . (yahoo.com)
Humans2
These insects have extremely long jaws, but surprisingly, they can barely cause any damage to humans through their bites. (whatsthatbug.com)
The female has shorter mandibles and can hurt humans by biting. (whatsthatbug.com)
Shorter1
In addition - also relative to weight - its jaws are slightly shorter, which increases the leverage for biting. (yahoo.com)
Smaller2
Although the lion ( Panthera leo ) is slightly smaller than the tiger, it has a stronger bite (1768 N), according to a 2005 review . (yahoo.com)
The female dobsonflies have smaller jaws and can generate enough biting force to break past the human skin and trigger pain. (whatsthatbug.com)
Species2
The species with biggest values of bite force quotient (BFQ) were Speothos venaticus (162.25), Cuon alpinus (129.24) and Lycaon pictus (124.41) due to several adaptations acquired along with hypercarnivory. (researchgate.net)
A 2012 study published in The Anatomical Record compared nine species of big cats to find that, while the tiger had the strongest bite force, the jaguar ( Panthera onca ) had the biggest bite for its size. (yahoo.com)
Diagnostic1
We describe a cost-effective device that uses an off-the-shelf force transducer to measure patient bite force as a diagnostic aid in determining dental implant size, number of implants, and prosthetic design for restoring partial edentulism. (allenpress.com)
Size4
In this scenario, mechanical forces on the skull once held back the evolution of brain size in early hominins. (johnhawks.net)
When those forces were relaxed by reducing the jaw musculature, brain size was free to increase. (johnhawks.net)
While the jaguar may have the strongest bite for its stature, the tiger proves size does matter (when it comes to bite strength). (yahoo.com)
If we exclude the size of the jaws, an adult dobsonfly can easily range from 2-4 inches in length . (whatsthatbug.com)
Prey3
Even more surprising is the fact that Dunkleosteus could also open its mouth very quickly - in just one fiftieth of a second - which created a strong suction force, pulling fast prey into its mouth. (bbc.co.uk)
Dunkleosteus was surrounded by possible prey that all required really high bite force," said Anderson, who works out of the University of Chicago. (bbc.co.uk)
Though hyenas are relatively small compared to other animals on this list, their hefty bite allows them to easily chow down on prey such as the giraffe in the background. (yahoo.com)
Show2
Male adult dobsonflies might look fearsome with their enormous mandibles, but these jaws are just for show. (whatsthatbug.com)
Yes, the bites from the female can be a little too painful to handle, but they won't show any long-term fatal effects on your body. (whatsthatbug.com)
Huge2
Although brown bears ( Ursus arctos ) primarily eat salmon and berries, they have some pretty huge jaws - and a bite to match. (yahoo.com)
Huge pincer-like jaws on a giant insect are a clear indicator of how dangerous it is, right? (whatsthatbug.com)
Human1
For context, a 2014 study found the average human bite force is 149-354 N, depending on age and sex. (yahoo.com)
Brain3
The main goal of this study is to test and explore the possible correlation between bite force and brain volume in canids. (researchgate.net)
For that, we calculated the bite force based on the beam theory, and the brain volume based on three cranial measurements. (researchgate.net)
Bite force and brain volume estimates are much higher in the group hunting hypercarnivores (Lycaon, Cuon and Speothos) and only these showed correlation between BFQ and BVQ. (researchgate.net)
Evolution2
The ways in which the taxonomic differences in morphology, behavior or life history relate to each other have been used regularly to test ideas about the selective forces involved in their evolution. (researchgate.net)

Device1
The truth is, most bite force data is simply an estimate, whether it comes from a computer model or from wild animals biting down on a device. (yahoo.com)

There is a linear increase in conductance and an increase in applied bite force. (allenpress.com)
