How to Watch Today's Solar Eclipse Live, No Cable Required. It’s finally here.

The total solar eclipse that hasn’t happened in the US since 1. But if you can’t see it in person, don’t sweat it. Gizmodo has got you covered. The total solar eclipse starts around 1. Pacific time and ends on the east coast around 3pm, with a partial eclipse on either end of that. The eclipse itself will last less than 3 minutes from any vantage point, but even if you’re not one of the millions of people expected to flock to the path of totality to view it in person, you can still watch online thanks to this glorious invention called the internet.

Bipedalism - Wikipedia. Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped, meaning "two feet" (from the Latinbis for "double" and pes for "foot").

Types of bipedal movement include walking, running, or hopping. Few modern species are habitual bipeds whose normal method of locomotion is two- legged. Within mammals, habitual bipedalism has evolved multiple times, with the macropods, kangaroo rats and mice, springhare,[4]hopping mice, pangolins and homininan apes, as well as various other extinct groups evolving the trait independently. In the Triassic period some groups of archosaurs (a group that includes the ancestors of crocodiles) developed bipedalism; among their descendants the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds; the birds descended from one group of exclusively bipedal dinosaurs.

A larger number of modern species intermittently or briefly use a bipedal gait. Several non- archosaurian lizard species move bipedally when running, usually to escape from threats. Many primate and bear species will adopt a bipedal gait in order to reach food or explore their environment. Several arboreal primate species, such as gibbons and indriids, exclusively walk on two legs during the brief periods they spend on the ground.

Many animals rear up on their hind legs whilst fighting or copulating. Some animals commonly stand on their hind legs, in order to reach food, to keep watch, to threaten a competitor or predator, or to pose in courtship, but do not move bipedally. Definition[edit]The word is derived from the Latin words bi(s) 'two' and ped- 'foot', as contrasted with quadruped 'four feet'. Advantages[edit]Limited and exclusive bipedalism can offer a species several advantages. Bipedalism raises the head; this allows a greater field of vision with improved detection of distant dangers or resources, access to deeper water for wading animals and allows the animals to reach higher food sources with their mouths.

While upright, non- locomotory limbs become free for other uses, including manipulation (in primates and rodents), flight (in birds), digging (in giant pangolin), combat (in bears, great apes and the large monitor lizard) or camouflage (in certain species of octopus). The maximum bipedal speed appears less fast than the maximum speed of quadrupedal movement with a flexible backbone – both the ostrich and the red kangaroo can reach speeds of 7. Even though bipedalism is slower at first, over long distances, it has allowed humans to outrun most other animals according to the endurance running hypothesis.[7] Bipedality in kangaroo rats has been hypothesized to improve locomotor performance, [clarification needed] which could aid in escaping from predators.[8][9]Facultative and obligate bipedalism[edit]Zoologists often label behaviors, including bipedalism, as "facultative" (i. Even this distinction is not completely clear- cut — for example, humans other than infants normally walk and run in biped fashion, but almost all can crawl on hands and knees when necessary. There are even reports of humans who normally walk on all fours with their feet but not their knees on the ground, but these cases are a result of conditions such as Uner Tan syndrome — very rare genetic neurological disorders rather than normal behavior.[1.

Even if one ignores exceptions caused by some kind of injury or illness, there are many unclear cases, including the fact that "normal" humans can crawl on hands and knees. This article therefore avoids the terms "facultative" and "obligate", and focuses on the range of styles of locomotion normally used by various groups of animals. Movement[edit]There are a number of states of movement commonly associated with bipedalism. Standing. Staying still on both legs.

In most bipeds this is an active process, requiring constant adjustment of balance. Walking. One foot in front of another, with at least one foot on the ground at any time. Running. One foot in front of another, with periods where both feet are off the ground. Jumping/hopping. Moving by a series of jumps with both feet moving together. Bipedal animals[edit]The great majority of living terrestrial vertebrates are quadrupeds, with bipedalism exhibited by only a handful of living groups. Humans, gibbons and large birds walk by raising one foot at a time.

On the other hand, most macropods, smaller birds, lemurs and bipedal rodents move by hopping on both legs simultaneously. Tree kangaroos are able to walk or hop, most commonly alternating feet when moving arboreally and hopping on both feet simultaneously when on the ground. Amphibians[edit]There are no known living or fossil bipedal amphibians.

Extant reptiles[edit]Many species of lizards become bipedal during high- speed, sprint locomotion, including the world's fastest lizard, the spiny- tailed iguana (genus Ctenosaura). Early reptiles and lizards[edit]The first known biped is the bolosaurid. Eudibamus whose fossils date from 2. Its long hindlegs, short forelegs, and distinctive joints all suggest bipedalism. The species became extinct in the early Permian. Archosaurs (include birds, crocodiles, and dinosaurs)[edit]All birds are bipeds when on the ground, a feature inherited from their dinosaur ancestors.

Other archosaurs[edit]Bipedalism evolved more than once in archosaurs, the group that includes both dinosaurs and crocodilians.[1. All dinosaurs are thought to be descended from a fully bipedal ancestor, perhaps similar to Eoraptor. Bipedal movement also re- evolved in a number of other dinosaur lineages such as the iguanodons. Some extinct members of the crocodilian line, a sister group to the dinosaurs and birds, also evolved bipedal forms - a crocodile relative from the triassic, Effigia okeeffeae, is thought to be bipedal.[1. Pterosaurs were previously thought to have been bipedal, but recent trackways have all shown quadrupedal locomotion.

Bipedalism also evolved independently among the dinosaurs. Dinosaurs diverged from their archosaur ancestors approximately 2. Watch Far Cry Torent Free. Middle to Late Triassic period, roughly 2.

Permian- Triassic extinction event wiped out an estimated 9. Earth.[1. 5][1. 6]Radiometric dating of fossils from the early dinosaur genus. Eoraptor establishes its presence in the fossil record at this time. Paleontologists suspect Eoraptor resembles the common ancestor of all dinosaurs; [1.

The discovery of primitive, dinosaur- like ornithodirans such as Marasuchus and Lagerpeton in Argentinian. Middle Triassic strata supports this view; analysis of recovered fossils suggests that these animals were indeed small, bipedal predators. Mammals[edit]A number of groups of extant mammals have independently evolved bipedalism as their main form of locomotion - for example humans, giant pangolins, the extinct giant ground sloths, numerous species of jumping rodents and macropods.

Humans, as their bipedalism has been extensively studied, are documented in the next section. Macropods are believed to have evolved bipedal hopping only once in their evolution, at some time no later than 4. Bipedal movement is less common among mammals, most of which are quadrupedal. All primates possess some bipedal ability, though most species primarily use quadrupedal locomotion on land. Primates aside, the macropods (kangaroos, wallabies and their relatives), kangaroo rats and mice, hopping mice and springhare move bipedally by hopping. Very few mammals other than primates commonly move bipedally by an alternating gait rather than hopping. Exceptions are the ground pangolin and in some circumstances the tree kangaroo.[2.

One black bear, Pedals, became famous locally and on the internet for having a frequent bipedal gait, although this is attributed to injuries on the bear's front paws. Primates[edit]Most bipedal animals move with their backs close to horizontal, using a long tail to balance the weight of their bodies.
