<P> 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 . </P> <P> 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 . 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 . 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 . </P> <P> 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 . 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 . 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 . 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 . </P> <P> 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 . </P>
