The animals desalrollaron la galopidad de galopar hace 472 millones de anos, alrededor de 260 millones de anos antes de emerger a la tierra, afirma un nuevo estudio.
Researchers have analyzed the existing literature on the 308 specimen walkie-talkies, not only mammoths, but also tambourines, reptiles and fish.
The ability to realize “asymmetric passages”, like galloping, has lost and won over many millions of years of evolution, so many more than the first animals in the land of 210 million years, experiencing experience.
The gallop is defined as a lot of things that are different in different moments and special deviations, according to academic people.
In addition to the gallop, it is associated with the caballos, the camels, leones, cocodrilos and giraffes, also used in the day of the distinctive fashion and the medica that augmentan la velocidad.
The ability to realize “asymmetric passages”, like galloping, is lost and won by the millionth year of evolution. Here, from B to E, there are examples of different asymmetrical modes: patear (B), move the mules (C), saltar (D) and gallop (E). Show a symmetrical throttle. The graphics on the deck of the image sequence represent the patrons of the associations associated with the shape of the andar. RH, right posterior right; RF, right anterior right; LF, left anterior membrane; LH, posterior outer area
The new studio was realized by Eric McElroy of the College of Charleston in Carolina del Sur and Michael Granatosky of the Institute of Technology of New York.
“From a neuromuscular perspective, any motor program that implies cyclical movements asynchronous to extremity pairs is an asymmetric mode,” he said.
“Our comparative analysis suggests that the asymmetric modes of experience will present the present in the most gnathostomas. [jawed vertebrates].
“Elaz hallazgo se suma al creciente cuerpo de trabajo que muestra que los primeros gnatóstomos et tetrapodos pueden haber usado una diversidad de formas de andar, incluido un patrón asimetrico de cyclismo de las extremidades».
The gallop is a form of movement of a selection of connoisseurs like ‘asymmetrical marches’, in which the type of caid of the pie is distributed in a designated manner.
Other samples of asymmetric markets include “salts” realized por conejos, muletas (cuando los peces anfibios se arrastran con sus aletas por la tierra) y bateas (cuando los peces se empujan a lo largo del mar o el lecho del río con sus sus aletas pélvicas).
In addition to the gallop, it is associated with the caballos, the distinctive tambourine is the key to the camels, leons, cocodrilos and giraffes in the middle that enhances the speed.
Previously, the scientists suggested that the ability to salt and gallop alone surpasses what the mammoths said by example in the planet about 210 million years ago.
But it is not possible to be at home, and the cocodrils can also gallop in their high-speed bicycles, generally escaping, showing that the tortures have the ability to salt as cones.
For the new studio, McElroy and Granatosky reviewed the scientific literature on the form of animals.
A genealogical tree is constructed from mammoths, marsupials, monotremas, reptiles, rans, sapos and peco conocidos by usar “ashes of dogs” asymmetrics when impulsed to the largo de la superficies con sus pies y aletas.
“We totally see 308 specimens,” said McElroy. “I can solve all the problems in the analysis.”
The team assigned a punctuation of 0 to the specs that only use walkways, tracks and tracks in regular times, and a punctuation of 1 to the specimens that most of the people have a signal of moving asymmetrically, shuffling, using mules, patendoo o galo.
On the other hand, the duo realized a series of simulations to prove that it is probable that the asymmetrical modes of apparatuses are equipped before the development of the evolutionary tree.
According to the hallasgos, the most probable ones are the examples of ancestors of all the modern animals, including the fish, there are 472 million of the years to be able to move with some kind of proto-asymmetric path.
No se sabe si pateaban, usaban muletas o saltaban a lo largo del lecho marino, pero los animales eran capaces de coordinar asimétricamente sus extremidades para impulsarse hacia adelante.
The researchers constructed a genealogical tree of the mammals, marsupials, monotremas, reptiles, rans, sapos and peco conocidos by using the “ashes of dogs” asymmetries when impulsed to the largo of the superficies with their feet and wings.
Curiously, some creatures, like lagartijas, salamanders, ranas and elephants included, he lost the ability to salt and gallop, to weigh those who were killed in the genealogical tree that he was able to do.
In the history of Tierra, the ability to salt and gallop is not limited to the mammoths: all the animals that live with you in the days of antiapasados that are able to move asymmetrically.
Muchos perdieron the ability to move asymmetrically probablely through the perdieron los nerves necesarios to coordinate est maniobras o porque se volvieron demasiado grandes o demasiado lentos para volar.
The authors conclude that the mammoths are not the only group selected with the ability to coordinate asymmetric movements.
It is possible that human beings inherit the ability of some people to take care of what is impulse to be at the margin of lecho marino with their aletas much more than any other kind of pussy and pie o una aleta en tierra firme.
The studio has been published in the Experimental Biology Review.
LOS DINOSAURIOS DE KUELLO LARGO TENÍAN UN ANDAR SIMILAR A UN HIPOPÓTAMO, ENCUENTRA UN ESTUDIO
The dinosaurs of the lark, including the diplodocus, have a different fashion and live different than any living animal, but more like a hippopotamus, a master of a recent studio.
Researchers study the huellas of the sauropods to learn more about the form of andar, the form that comes with a walk, the Formation of the Queen of Cretácico Inferior, Arkansas.
Al igual que los hippopotamos, lo sauropods caminaban con una ‘marcha diagonal’, en la que cada paso de una pata delantera va en conjunto con la pata trasera del lado opuesto o muy de cerca.
Usando la marcha diagonal habría permitió que los dinosaurios mantuvieran sus marcos anchos en equilibrio, encontraron los investigadores.
Al igual que los hippopotamos, lo sauropods caminaban con una ‘marcha diagonal’, en la que cada paso de una pata delantera va en conjunto con la pata trasera del lado opuesto o muy de cerca. The elephants have the right to take a “lateral” fashion, because of the extremities of the middle of the body of the body, the movers will be able to move on.
In comparison, the elephants use a llamado marcha “lateral” in which the extremities of the middle of the body of the body tend to move to the other side.
Entonces, la pata delantera derecha da un paso, seguida por la pata trasera derecha dando un paso, luego la pata delantera izquierda, luego la pata trasera izquierda, y así sucesivamente.
“The sauropods eligieron un modo de andar que maximizaba la estabilidad pero que aún permitía caminar de manera eficiente”, dijo el autor del estudio, el Dr. Jens Lallensack, of the John Moores University of Liverpool.
