Ocala Demands
From Wikipedia, the free encyclopedia
Jump to: navigation, search
The Ocala Demands was a platform for economic and political reform that was later adopted by the People's Party.
In December, 1890, the National Farmers' Alliance and Industrial Union, more commonly known as the Southern Farmers' Alliance, its affiliate the Colored Farmers' Alliance, and the Farmers' Mutual Benefit Association met jointly in the Marion Opera House in Ocala, Florida, where they adopted the Ocala Demands.

Context in the Farmers' Movement[edit]
The Ocala convention was part of a trend in the Farmers' movement of moving from its fraternal and mutual benefit roots towards an increasingly political and radical position. Earlier in the year the Farmers' Alliance had successfully backed a number of candidates for state and Federal office, and the convention delegates hoped that future political gains would lead to major economic and political reforms.
Content[edit]
The "Demands" adopted by the Ocala convention called for the abolition of national banks; the establishment of sub-treasuries or depositories in every state, which would make low interest direct loans to farmers and property owners; the increase of money in circulation to not less than $50 per capita; the abolishment of futures of all agricultural and mechanical productions; the introduction of free silver; the prohibition of alien ownership of land, the reclamation of all lands held by railroads and other corporations in excess of what was actually used and needed by them, held for actual settlers only; legislation to ensure that one industry was not be built up at the expense of another; removal of the tariff tax on necessities of life; a graduated income tax; the limitation of all national and state revenues to the necessary expenses of the government economically and honestly administered; strict regulation or ownership of the means of public communication and transportation; and an amendment of the United States Constitution providing for the direct election of United States Senators.
Result[edit]
In 1892 the Farmers' Alliance founded the People's (or Populist) Party, and the Ocala Demands were incorporated in the party's Omaha Platform. As the focus of the Farmers' Movement shifted into politics, the Farmer's Alliance faded away.
Text[edit]
1: We demand the abolition of national banks.
2: We demand that the government shall establish sub-treasuries or depositories in the several states, which shall loan money direct to the people at a low rate of interest, not to exceed two per cent per annum, on non-perishable farm products, and also upon real estate, with proper limitations upon the quantity of land and amount of money.
3: We demand that the amount of the circulating medium be speedily increased to not less than $50 per capita.
4: We demand that Congress shall pass such laws as will effectually prevent the dealing in futures of all agricultural and mechanical productions; providing a stringent system of procedure in trials that will secure the prompt conviction, and imposing such penalties as shall secure the most perfect compliance with the law.
5: We condemn the silver bill recently passed by Congress, and demand in lieu thereof the free and unlimited coinage of silver.
6: We demand the passage of laws prohibiting alien ownership of land, and that Congress take prompt action to devise some plan to obtain all lands now owned by aliens and foreign syndicates; and that all lands now held by railroads and other corporations in excess of such as is actually used and needed by them be reclaimed by the government and held for actual settlers only.
7: Believing in the doctrine of equal rights to all and special privileges to none, we demand—a: That our national legislation shall be so framed in the future as not to build up one industry at the expense of another.
b: We further demand a removal of the existing heavy tariff tax from the necessities of life, that the poor of our land must
c: We further demand a just and equitable system of graduated tax on incomes.
d: We believe that the money of the county should be kept as much as possible in the hands of the people, and hence we demand that all national and state revenues shall be limited to the necessary expenses of the government economically and honestly administered.
e: We demand the most rigid, honest and just state and national government control and supervision of the means of public communication and transportation, and if this control and supervision does not remove the abuse now existing, we demand the government ownership of such means of communication and transportation.
f: We demand that the Congress of the United States submit an amendment to the Constitution providing for the election of United States Senators by direct vote of the people of each state.

The Battle of Issus occurred in southern Anatolia, on November 5, 333 BC between the Hellenic League led by Alexander the Great and the Achaemenid Empire, led by Darius III, in the second great battle of Alexander's conquest of Asia. The invading Macedonian troops defeated Persia. After the Hellenic League soundly defeated the Persian satraps of Asia Minor (led by Greek mercenary Memnon of Rhodes) at the Battle of the Granicus, Darius took personal command of his army. He gathered reinforcements and led his men in a surprise march behind the Hellenic advance to cut their line of supply. This forced Alexander to countermarch, setting the stage for the battle near the mouth of the Pinarus River and the town of Issus.

Location
The battle of Issus by Jan Brueghel the Elder in the Louvre
The battle took place south of the ancient town Issus, which is close to the present-day Turkish town of Iskenderun (the Turkish equivalent of "Alexandria", founded by Alexander to commemorate his victory), on either side of a small river called Pinarus. At that location, the distance from the Gulf of Issus to the surrounding mountains is only 2.6 km (2 mi), a place where Darius could not take advantage of his superiority in numbers. Speculation on the location of the Pinarus has taken place for over 80 years. Older historians believed it to be the Deli Tchai river, but historians N.G.L. Hammond and A. M. Devine claim that the Pinarus is actually the Payas River, the latter using his own examination of the course of the river, which he considered would not have drastically changed since antiquity. Their evidence is based on Callisthenes' accounts of the measurements of the battlefield and distances marched by both sides' armies in the prelude to the battle and distance given by Diodorus after the battle.
Background
Movements to the battlefield. Red indicates Persian forces, and blue indicates Macedonian forces.
Alexander set out into Asia in 334 BC and defeated the local Persian satraps at the Battle of the Granicus. He then proceeded to occupy all of Asia Minor, with the idea of capturing all coastal settlements so as to negate the power of the vastly superior Persian fleet. He captured several important settlements such as Miletus in 334 BC and Halicarnassus, a siege lasting four months, starting in late December the same year. While Alexander was in Tarsus, he heard of Darius massing a great army in Babylon. If Darius were to reach the Gulf of Issus, he could use the support from the Persian fleet under Pharnabazus still operating in the Mediterranean Sea, thus easing his supply and possibly landing troops behind the enemy. Alexander kept his main army at Tarsus but sent Parmenion ahead to occupy the coast around Issus. In November, Alexander received reports that the great Persian army had advanced into Syria to a town named Sochoi. Alexander decided to mass his scattered army and advance south from Issus through the Pass of Jonah.
Darius knew that Parmenion held the Pass of Jonah and thus chose a northern route of advance. The Persians captured Issus without opposition and cut off the hands of all the sick and wounded that Alexander had left behind. Now Darius found out he had placed his army behind the Hellenic League and had cut their supply lines. He then advanced to the south and got no further than the river Pinarus before his scouts spotted Alexander marching north. Darius had to set up camp on this narrow coastal plain.
Motives
Initial dispositions of Persian and Macedonian forces
There is much debate as to the motives of Alexander and Darius preceding Issus. One modern perspective, based on Curtius, is that Darius was forced to move camp to terrain that favored Alexander because Alexander was fighting defensively due to a recommendation by his war council and Parmenion.[citation needed] Darius' large army could not be supported in the field during winter and his cities in Phoenicia were already in unrest at the arrival of Alexander. Darius was forced to move his large army to a small battlefield, greatly to the advantage of Alexander's smaller force.
Alexander was waiting for Darius to come south around the Amanus Mountain range because the pass Darius would have used, the Belen Pass, was much closer to Sochi and offered the quickest access to the area Alexander defended. Alexander was waiting 15 km (9.3 mi) to the west of the Belen Pass at Myriandrus to spring a trap on Darius as he crossed through the Belen Pass or through the Pillar of Jonah if he moved north, where Darius' army would be disorganized and disjointed in the narrow crossing. Darius instead moved north from Sochi and around the mountains, emerging behind Alexander's position and on his supply and communication lines. Thus Alexander was forced to march to Darius, who had caught him off guard in a large flanking maneuver. This gives the illusion that Darius was the one acting defensively, since Alexander was forced to march to him.
Combatants
Persian army
Some ancient sources (Arrian and Plutarch), who based their accounts on earlier Greek sources, estimated 600,000[2] Persian soldiers in total, while Diodorus and Justin estimated 400,000, and Curtius Rufus estimated 250,000.
Modern historians find Arrian's count of 600,000 men highly unlikely. They argue that the logistics of fielding more than 100,000 soldiers in battle was extremely difficult at the time. Hans Delbrück gives an estimate as small as 25,000, although most (including Engels and Green) estimate the total size of Darius' army to be no larger than 100,000 at Issus,[4] including 11,000 cavalry,[2] 10,000 Persian Immortals, and 10,000 Greek mercenaries.[5] Warry estimates 108,000 in total.
Macedonian army
The size of the Hellenic army may not have exceeded 40,000 men, including their other allies, led by Alexander. Alexander's army may have consisted of about 22,000 phalangites and hoplites, 13,000 peltasts, and 5,850 cavalry.[2]
Battle
The Greeks advanced through the Pillar of Jonah. Alexander led his Companion cavalry on the right flank and he set his Thessalian allied cavalry on the left of the phalanx with Parmenion in command.
Darius formed his line with his heavy cavalry concentrated next to the coast on his right, followed by the Greek mercenary phalanx (historian A. M. Devine places them at a strength of 12,000, comparable to Alexander's Greek phalanx). Next to the Greek phalanx Darius spread his Persian infantry, the Cardaces, along the river and into the foothills, where they wrapped around to the other bank and threatened Alexander's right flank (the formation resembled gamma, Γ). Arrian gives an inflated figure of 20,000 to these troops. Darius positioned himself in the centre with his best infantry, the Greek mercenaries, and his royal cavalry guard. According to some historians, like P. Stratikis, he was trying to replicate the Hellenic battle formation of the Battle of the Granicus.
Alexander's decisive attack
The Persian cavalry first charged Parmenion and the allied cavalry, crossing the river to open battle. Alexander's right wing became the crux of the battle, as at Gaugamela two years later, where Parmenion held the left wing long enough against superior Persian numbers for Alexander to make his calculated cavalry strike against Darius and break the Persian army.[7] The infantry of the Greek left flank was commanded by the general Craterus, in a promotion from his position commanding a single brigade of pezhetairoi infantry at the Granicus.[8]
Things did not go well for the Macedonians in the beginning. Their center phalanx, having to advance across a river and up a fortified bank, suffered severely against the Greek mercenaries waiting for them on the other side. Arrian noted that a hundred and twenty Macedonians “of note” (probably meaning officers) were slain here, and the Macedonians were forced to retreat across the river. In the left flank, the Thessalian struggled against the outnumbering mass of Persian heavy horse that faced them, delivering charges and retreating again to buy time.
Then the Hypaspists led by Alexander on foot delivered an assault on the Cardaces, and managed to punch a hole through the Persian line. The Agrianians too drove back a mass of Persian skirmishers menacing Alexander's far right, securing the flank of the Companions. Alexander then mounted a horse at the head of his Companions and led a direct assault against Darius and his bodyguards, causing them to flee from the battlefield. Alexander then saw his left flank and center in trouble, and allowing Darius to flee, he crashed into the rear of the Greek mercenaries. The Greek mercenaries broke up and started retreating from the battlefield as well. The Persians saw that their Great King had gone and that the battle was being lost, and they abandoned their positions and fled in full rout. The Hellenic cavalry pursued the fleeing Persians for as long as there was light. As with most ancient battles, significant carnage occurred after the battle as the pursuing Greeks slaughtered their crowded, disorganized foe. Arrian notes Ptolemy mentioning that while pursuing Darius, Alexander and his bodyguards came upon a ravine which they easily crossed on the piled up bodies of dead Persians. It was a decisive victory for Alexander.
Aftermath
The family of Darius in front of Alexander, by Justus Sustermans and displayed in the Biblioteca Museu Víctor Balaguer
The Battle of Issus was a decisive Hellenic victory and it marked the beginning of the end of Persian power. It was the first time the Persian army had been defeated with the King (Darius III at the time) present. After the battle, the Hellenes captured Darius' wife, Stateira I, his daughters, Stateira II and Drypetis, and his mother, Sisygambis, all of whom had accompanied Darius on his campaign. Alexander, who later married Stateira II, treated the captured women with great respect.
Depictions of the battle
Altdorfer's The Battle of Alexander at Issus
German Renaissance painter and printmaker Albrecht Altdorfer (c. 1480–1538) dramatically depicted the battle in his 1529 painting The Battle of Alexander at Issus.
The Battle of Issus (c. 1599–1600) by Jan Brueghel the Elder (1568–1625) hangs in the Louvre.
American Abstract Expressionist painter Cy Twombly diagrammed the battle in his 1968 painting Synopsis of a Battle.[9]
The 2004 Oliver Stone film Alexander was expected to depict the battle, instead, it put elements of the Battle of the Granicus, Issus, and Gaugamela all together. It was labeled as the Battle of Gaugamela but held distinctive elements of all three battles. The Battle of the Hydaspes River was also featured.
Contemporary fine-artist Rossi d'Providence has created an oil painting of the Battle at Issus for the Classics Department at Brown University in Providence, Rhode Island.[10]

Map of Pangaea with modern continental outlines
Pangaea or Pangea ( /pænˈdʒiːə/[1]) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras.[2][3] It assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago.[4] In contrast to the present Earth and its distribution of continental mass, much of Pangaea was in the southern hemisphere and surrounded by a superocean, Panthalassa. Pangaea was the most recent supercontinent to have existed and the first to be reconstructed by geologists.

The name "Pangaea/Pangea" is derived from Ancient Greek pan (πᾶν, "all, entire, whole") and Gaia (Γαῖα, "Mother Earth, land").[5][10] The concept that the continents once formed a continuous land mass was first proposed by Alfred Wegener, the originator of the scientific theory of continental drift, in his 1912 publication The Origin of Continents (Die Entstehung der Kontinente).[11] He expanded upon his hypothesis in his 1915 book The Origin of Continents and Oceans (Die Entstehung der Kontinente und Ozeane), in which he postulated that, before breaking up and drifting to their present locations, all the continents had formed a single supercontinent that he called the "Urkontinent".
The name "Pangea" occurs in the 1920 edition of Die Entstehung der Kontinente und Ozeane, but only once, when Wegener refers to the ancient supercontinent as "the Pangaea of the Carboniferous".[12] Wegener used the Germanized form "Pangäa", but the name entered German and English scientific literature (in 1922[13] and 1926, respectively) in the Latinized form "Pangaea" (of the Greek "Pangaia"), especially due to a symposium of the American Association of Petroleum Geologists in November 1926.[14]
Formation
Appalachian orogeny
The forming of supercontinents and their breaking up appears to have been cyclical through Earth's history. There may have been many others before Pangaea. The fourth-last supercontinent, called Columbia or Nuna, appears to have assembled in the period 2.0–1.8 Ga.[15][16] Columbia/Nuna broke up and the next supercontinent, Rodinia, formed from the accretion and assembly of its fragments. Rodinia lasted from about 1.1 billion years ago (Ga) until about 750 million years ago, but its exact configuration and geodynamic history are not nearly as well understood as those of the later supercontinents, Pannotia and Pangaea.
When Rodinia broke up, it split into three pieces: the supercontinent of Proto-Laurasia, the supercontinent of Proto-Gondwana, and the smaller Congo craton. Proto-Laurasia and Proto-Gondwana were separated by the Proto-Tethys Ocean. Next Proto-Laurasia itself split apart to form the continents of Laurentia, Siberia and Baltica. Baltica moved to the east of Laurentia, and Siberia moved northeast of Laurentia. The splitting also created two new oceans, the Iapetus Ocean and Paleoasian Ocean. Most of the above masses coalesced again to form the relatively short-lived supercontinent of Pannotia. This supercontinent included large amounts of land near the poles and, near the equator, only a relatively small strip connecting the polar masses. Pannotia lasted until 540 Ma, near the beginning of the Cambrian period and then broke up, giving rise to the continents of Laurentia, Baltica, and the southern supercontinent of Gondwana.
In the Cambrian period, the continent of Laurentia, which would later become North America, sat on the equator, with three bordering oceans: the Panthalassic Ocean to the north and west, the Iapetus Ocean to the south and the Khanty Ocean to the east. In the Earliest Ordovician, around 480 Ma, the microcontinent of Avalonia – a landmass incorporating fragments of what would become eastern Newfoundland, the southern British Isles, and parts of Belgium, northern France, Nova Scotia, New England, South Iberia and northwest Africa – broke free from Gondwana and began its journey to Laurentia.[17] Baltica, Laurentia, and Avalonia all came together by the end of the Ordovician to form a minor supercontinent called Euramerica or Laurussia, closing the Iapetus Ocean. The collision also resulted in the formation of the northern Appalachians. Siberia sat near Euramerica, with the Khanty Ocean between the two continents. While all this was happening, Gondwana drifted slowly towards the South Pole. This was the first step of the formation of Pangaea.[18]
The second step in the formation of Pangaea was the collision of Gondwana with Euramerica. By Silurian time, 440 Ma, Baltica had already collided with Laurentia, forming Euramerica. Avalonia had not yet collided with Laurentia, but as Avalonia inched towards Laurentia, the seaway between them, a remnant of the Iapetus Ocean, was slowly shrinking. Meanwhile, southern Europe broke off from Gondwana and began to move towards Euramerica across the newly formed Rheic Ocean. It collided with southern Baltica in the Devonian, though this microcontinent was an underwater plate. The Iapetus Ocean's sister ocean, the Khanty Ocean, shrank as an island arc from Siberia collided with eastern Baltica (now part of Euramerica). Behind this island arc was a new ocean, the Ural Ocean.
By late Silurian time, North and South China split from Gondwana and started to head northward, shrinking the Proto-Tethys Ocean in their path and opening the new Paleo-Tethys Ocean to their south. In the Devonian Period, Gondwana itself headed towards Euramerica, causing the Rheic Ocean to shrink. In the Early Carboniferous, northwest Africa had touched the southeastern coast of Euramerica, creating the southern portion of the Appalachian Mountains, the Meseta Mountains and the Mauritanide Mountains. South America moved northward to southern Euramerica, while the eastern portion of Gondwana (India, Antarctica and Australia) headed toward the South Pole from the equator. North and South China were on independent continents. The Kazakhstania microcontinent had collided with Siberia. (Siberia had been a separate continent for millions of years since the deformation of the supercontinent Pannotia in the Middle Carboniferous.)
Western Kazakhstania collided with Baltica in the Late Carboniferous, closing the Ural Ocean between them and the western Proto-Tethys in them (Uralian orogeny), causing the formation of not only the Ural Mountains but also the supercontinent of Laurasia. This was the last step of the formation of Pangaea. Meanwhile, South America had collided with southern Laurentia, closing the Rheic Ocean and forming the southernmost part of the Appalachians and Ouachita Mountains. By this time, Gondwana was positioned near the South Pole and glaciers were forming in Antarctica, India, Australia, southern Africa and South America. The North China block collided with Siberia by Late Carboniferous time, completely closing the Proto-Tethys Ocean.
By early Permian time, the Cimmerian plate split from Gondwana and headed towards Laurasia, thus closing the Paleo-Tethys Ocean, but forming a new ocean, the Tethys Ocean, in its southern end. Most of the landmasses were all in one. By the Triassic Period, Pangaea rotated a little and the Cimmerian plate was still travelling across the shrinking Paleo-Tethys, until the Middle Jurassic time. The Paleo-Tethys had closed from west to east, creating the Cimmerian Orogeny. Pangaea, which looked like a C, with the new Tethys Ocean inside the C, had rifted by the Middle Jurassic, and its deformation is explained below.
Evidence of existence
The distribution of fossils across the continents is one line of evidence pointing to the existence of Pangaea.
Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. For example, fossils of the therapsid Lystrosaurus have been found in South Africa, India and Antarctica, alongside members of the Glossopteris flora, whose distribution would have ranged from the polar circle to the equator if the continents had been in their present position; similarly, the freshwater reptile Mesosaurus has been found in only localized regions of the coasts of Brazil and West Africa.[19]
Additional evidence for Pangaea is found in the geology of adjacent continents, including matching geological trends between the eastern coast of South America and the western coast of Africa. The polar ice cap of the Carboniferous Period covered the southern end of Pangaea. Glacial deposits, specifically till, of the same age and structure are found on many separate continents which would have been together in the continent of Pangaea.[20]
Paleomagnetic study of apparent polar wandering paths also support the theory of a supercontinent. Geologists can determine the movement of continental plates by examining the orientation of magnetic minerals in rocks; when rocks are formed, they take on the magnetic properties of the Earth and indicate in which direction the poles lie relative to the rock. Since the magnetic poles drift about the rotational pole with a period of only a few thousand years, measurements from numerous lavas spanning several thousand years are averaged to give an apparent mean polar position. Samples of sedimentary rock and intrusive igneous rock have magnetic orientations that are typically an average of the "secular variation" in the orientation of magnetic north because their remanent magnetizations are not acquired instantaneously. Magnetic differences between sample groups whose age varies by millions of years is due to a combination of true polar wander and the drifting of continents. The true polar wander component is identical for all samples, and can be removed, leaving geologists with the portion of this motion that shows continental drift and can be used to help reconstruct earlier continental positions.[21]
The continuity of mountain chains provides further evidence for Pangaea. One example of this is the Appalachian Mountains chain which extends from the southeastern United States to the Caledonides of Ireland, Britain, Greenland, and Scandinavia.[22]
Rifting and break-up
Animation of the rifting of Pangaea
There were three major phases in the break-up of Pangaea. The first phase began in the Early-Middle Jurassic (about 175 Ma), when Pangaea began to rift from the Tethys Ocean in the east to the Pacific in the west. The rifting that took place between North America and Africa produced multiple failed rifts. One rift resulted in a new ocean, the North Atlantic Ocean.[22]
The Atlantic Ocean did not open uniformly; rifting began in the north-central Atlantic. The South Atlantic did not open until the Cretaceous when Laurasia started to rotate clockwise and moved northward with North America to the north, and Eurasia to the south. The clockwise motion of Laurasia led much later to the closing of the Tethys Ocean and the widening of the "Sinus Borealis", which later became the Arctic Ocean. Meanwhile, on the other side of Africa and along the adjacent margins of east Africa, Antarctica and Madagascar, new rifts were forming that would lead to the formation of the southwestern Indian Ocean that would open up in the Cretaceous.
The second major phase in the break-up of Pangaea began in the Early Cretaceous (150–140 Ma), when the minor supercontinent of Gondwana separated into multiple continents (Africa, South America, India, Antarctica, and Australia). The subduction at Tethyan Trench probably caused Africa, India and Australia to move northward, causing the opening of a "South Indian Ocean". In the Early Cretaceous, Atlantica, today's South America and Africa, finally separated from eastern Gondwana (Antarctica, India and Australia). Then in the Middle Cretaceous, Gondwana fragmented to open up the South Atlantic Ocean as South America started to move westward away from Africa. The South Atlantic did not develop uniformly; rather, it rifted from south to north.
Also, at the same time, Madagascar and India began to separate from Antarctica and moved northward, opening up the Indian Ocean. Madagascar and India separated from each other 100–90 Ma in the Late Cretaceous. India continued to move northward toward Eurasia at 15 centimeters (6 in) a year (a plate tectonic record), closing the eastern Tethys Ocean, while Madagascar stopped and became locked to the African Plate. New Zealand, New Caledonia and the rest of Zealandia began to separate from Australia, moving eastward toward the Pacific and opening the Coral Sea and Tasman Sea.
The third major and final phase of the break-up of Pangaea occurred in the early Cenozoic (Paleocene to Oligocene). Laurasia split when North America/Greenland (also called Laurentia) broke free from Eurasia, opening the Norwegian Sea about 60–55 Ma. The Atlantic and Indian Oceans continued to expand, closing the Tethys Ocean.
Meanwhile, Australia split from Antarctica and moved quickly northward, just as India had done more than 40 million years before. Australia is currently on a collision course with eastern Asia. Both Australia and India are currently moving northeast at 5–6 centimeters (2–3 in) a year. Antarctica has been near or at the South Pole since the formation of Pangaea about 280 Ma. India started to collide with Asia beginning about 35 Ma, forming the Himalayan orogeny, and also finally closing the Tethys Seaway; this collision continues today. The African Plate started to change directions, from west to northwest toward Europe, and South America began to move in a northward direction, separating it from Antarctica and allowing complete oceanic circulation around Antarctica for the first time. This motion, together with decreasing atmospheric carbon dioxide concentrations, caused a rapid cooling of Antarctica and allowed glaciers to form. This glaciation eventually coalesced into the kilometers-thick ice sheets seen today.[23] Other major events took place during the Cenozoic, including the opening of the Gulf of California, the uplift of the Alps, and the opening of the Sea of Japan. The break-up of Pangaea continues today in the Red Sea Rift and East African Rift.
Tectonic plate shift
The breakup of Pangaea over time
Pangaea's formation is now commonly explained in terms of plate tectonics. The involvement of plate tectonics in Pangaea's[24] separation helps to show how it did not separate all at once, but at different times, in sequences. Additionally, after these separations, it has also been discovered that the separated land masses may have also continued to break apart multiple times. The formation of each environment and climate on Pangaea is due to plate tectonics, and thus, it is as a result of these shifts and changes different climatic pressures were placed on the life on Pangaea. Although plate tectonics was paramount in the formation of later land masses, it was also essential in the placement, climate, environments, habitats, and overall structure of Pangaea.[25]
What can also be observed in relation to tectonic plates and Pangaea, is the formations to such plates. Mountains and valleys form due to tectonic collisions as well as earthquakes and chasms. Consequentially, this shaped Pangaea and animal adaptations. Furthermore, plate tectonics can contribute to volcanic activity,[26] which is responsible for extinctions and adaptations which have evidently affected life over time, and without doubt on Pangaea.
Life
Example of an ammonite
For the approximately 160 million years Pangaea existed, many species had fruitful times whereas others struggled. The Traversodontidae[27] is an example of such prospering animals, eating a diet of only plants. Plants dependent on spore reproduction had been taken out of the ecosystems, and replaced by the gymnosperm plant, which reproduces through the use of seeds instead. Later on, insects (beetles, dragonflies, mosquitos) also thrived during the Permian period 299 to 252 million years ago.[28] However, the Permian extinction at 252 Mya greatly impacted these insects in mass extinction, being the only mass extinction to affect insects. When the Triassic Period came, many reptiles were able to also thrive, including Archosaurs, which were an ancestor to modern-day crocodiles and birds.
Little is known about marine life during the existence of Pangaea. Scientists are unable to find substantial evidence or fossilized remains in order to assist them in answering such questions. However, a couple of marine animals have been determined to have existed at the time- the Ammonites and Brachiopods. Additionally, evidence pointing towards massive reefs with varied ecosystems, especially in the species of sponges and coral, have also been discovered.[citation needed]
Climate change after Pangaea
Pangaea has tremendously affected the setup of the world now. In the post Pangaea time period, the reconfiguration of continents and oceans has changed the climate of many areas. There is scientific evidence that proves that climate was drastically altered. When the continents separated and reformed themselves, it changed the flow of the oceanic currents and winds. The scientific reasoning behind all of the changes is Continental Drift. The theory of Continental Drift, created by Alfred Wegener, explained how the continents shifted Earth’s surface and how that affected many aspects such as climate, rock formations found on different continents and plant and animal fossils.[29] Wegener studied plant fossils from the frigid Arctic of Svalbard, Norway. He determined that such plants were not meant to adapt to a glacial climate. The fossils he found were from tropical plants that were meant to adapt and thrive in warmer and tropical climate.[30] Because we would not assume that the plant fossils were capable of traveling to a different place we suspect that Svalbard possibly had a warmer, less frigid climate in the past.[31]
When Pangaea separated, the reorganization of the continents changed the function of the oceans and seaways. The restructuring of the continents, changed and altered the distribution of warmth and coolness of the oceans. When North America and South America connected, it stopped equatorial currents from passing from the Atlantic Ocean to the Pacific Ocean.[32] Researchers have found evidence by using computer hydrological models to show that this strengthened the Gulf Stream by diverting more warm currents towards Europe. Warm waters at high latitudes led to an increased evaporation and eventually atmospheric moisture. Increased evaporation and atmospheric moisture resulted in increased precipitation. Evidence of increased precipitation is the development of snow and ice that covers Greenland, which led to an accumulation of the icecap. Greenland’s growing ice cap led to further global cooling.[32] Scientists also found evidence of global cooling through the separation of Australia and Antarctica and the formation of the Antarctic Ocean. Ocean currents in the newly formed Antarctic or Southern Ocean created a circumpolar current.[32] The creation of the new ocean that caused a circumpolar current eventually led to atmospheric currents that rotated from west to east. Atmospheric and oceanic currents stopped the transfer of warm, tropical air and water to the higher latitudes. As a result of the warm air and currents moving northward, Antarctica cooled down so much that it became frigid.
Although many of Alfred Wegener’s theories and conclusions were valid, scientists are constantly coming up with new innovative ideas or reasoning behind why certain things happen. Wegener’s theory of Continental Drift was later replaced by the theory of tectonic plates.[33]
Implications of extinction
There is evidence to suggest that the deterioration of northern Pangaea contributed to the Permian Extinction, one of Earth’s five major mass extinction events, which resulted in the loss of over 90% of marine and 70% of terrestrial species. There were three main sources of environmental deterioration which are believed to have had a hand in the extinction event.
The first of these sources is a loss of oxygen concentration in the ocean which caused deep water regions called the lysocline to grow shallower. With the lysocline shrinking, there were fewer places for calcite to dissolve in the ocean, considering calcite only dissolves at deep ocean depths. This led to the extinction of carbonate producers such as brachiopods and corals that relied on dissolved calcite to survive. The second source is the eruption of the Siberian Traps, a large volcanic event which is argued to be the result of Pangaean tectonic movement.[34] This had several negative repercussions on the environment, including metal loading and excess atmospheric carbon. Metal loading, the release of toxic metals from volcanic eruptions into the environment, led to acid rain and general stress on the environment. These toxic metals are known to infringe on vascular plants’ ability to photosynthesize, which may have resulted in the loss of Permian-era flora. Excess carbon dioxide in the atmosphere is believed to be the main cause of the shrinking of lysocline areas.
The third cause of this extinction event that can be attributed to northern Pangaea is the beginnings of anoxic ocean environments, or oceans with very low oxygen concentrations. The mix of anoxic oceans and ocean acidification due to metal loading led to increasingly acidic oceans,[35] which ultimately led to the extinction of Benthos.[36]
