  1. the Permian extinction is the largest of a known mass
  2. extinction, wiping out pretty much everything everywhere.
  3. The living organisms during the Permian period was very diverse,
  4. especially marine life in the shallow oceans that a large
  5. race and large amounts of life.
  6. Although the most common were emanates and branch earbuds.
  7. Terrestrial vertebrates such as a sign ups and syrup odds
  8. dominated the land during the Permian.
  9. This great dying was going to have wiped out nearly
  10. 96% of all marine species and 70% of terrestrial vertebrates.
  11. This extinction sent trailer by its blast roids and many
  12. more marine species extinct.
  13. Killing over 95% of branch applauds, emanates and many more.
  14. The extent of this extinction had a large effect on
  15. the earth.
  16. The Permian occurred over 15 million years from 299 million
  17. years ago to 251 million years ago.
  18. The conditions of the end Permian became unsuitable for most
  19. life. In that year, the Permian illuminated majority of the
  20. marine and terrestrial left, giving this period the nickname the
  21. great Dying.
  22. This set life back over 300 million years.
  23. Throughout research over the years, there are many theories reported
  24. about the cause of this event, I'll be discussing two
  25. of many alongside the evidence of them.
  26. Mass volcanic eruptions is one of the proposed theories that
  27. triggered the end Permian and strongly influenced this mass extinction.
  28. The Siberian traps in northeastern Siberia erupted over 250 million
  29. years ago, contributing as much as three million kilometers cube
  30. of ash high into the atmosphere.
  31. The secondary effect of the volcano set off train effects
  32. into the atmosphere, sending ariz holes and ash clouds that
  33. blocked out the sun black, darkening the skies and lowering
  34. the temperature.
  35. These temperatures and newbie impacted the cause of the terrestrial
  36. life, making it vulnerable to harmful amounts of radiation.
  37. The results of the darkening of the planet.
  38. We would have caused a significant drop in the temperature.
  39. Also present preventing the process of photosynthesize ing.
  40. After the cool period of the Permian, there was lots
  41. off UV exposure causing trapped aerosols, strangers temperature by up
  42. to 11 degrees.
  43. There are theirry option of this volcano.
  44. Released gas is having a strong contribution toe asked to
  45. drain that would have polluted many bodies of water, raising
  46. the acidity, making the oceans in hospital tow left.
  47. Another theory for this extinction is the formation of Panja.
  48. The collection of small continents to create a super continent
  49. of Pangea was one of many theories proposed to explain
  50. this mass extinction.
  51. This assembly was completed by the mid parrot Permian, with
  52. the scattered continents gathering having an area nearly 200 million
  53. square kilometers.
  54. This resulted in a single continent having one ocean around
  55. it, known as pants.
  56. Lamia. Having such a large landmass would have made a
  57. big change in circulation off the earth's oceans, resulting in
  58. major climate change in the sea level to rise and
  59. fall. The rows of fossil and dating is to keep
  60. us up to date with the diverse history of our
  61. planet. Since the Permian, as since the Permian Earth has
  62. changed dramatically, continents have moved far distances the oceans have
  63. worn and froze in mountains have been formed.
  64. During these changes, many species have evolved and become extinct,
  65. leaving behind many fossils.
  66. After the Permian extinction, there was a large amount of
  67. fossils and traces of fossils.
  68. These fossils are the most of the organisms that have
  69. existed and created the fossil.
  70. This is evidence of the existence of these life forms
  71. during the time period.
  72. Brussels Allow us to put into context what geological area
  73. this event or species was present.
  74. They can help geo a geo.
  75. Geologists and paleontologists get a better understanding of what happened
  76. or why it happened by studying the mold of the
  77. fossils. It shows us what the object looks like and
  78. what what may have caused its extinction.
  79. Although this is helpful, the age of the relatives fossils
  80. must be present, so we are able to compare and
  81. analyze the new discoveries.
  82. Without the Permian event, Earth would not be how it
  83. is today, but this mass extinction wiping out 96% of
  84. marine life and over 70% of terrestrial life.
  85. It's set back us over 300 billion years.
  86. The small percentage of species that were around before the
  87. explosion continued to involve.
  88. Although this extinction was the beginning of new species, allowing
  89. them to develop and dominate because earth was set back
  90. so far, the evolution of Earth was slowed, having to
  91. grow all from the beginning, making all species have to
  92. adapt to new environmental conditions.
  93. Whilst the Permian extinction ended, it was the beginning of
  94. the Triassic period and the Jurassic extinction.
  95. Without the permission, the life we have on Earth today
  96. would be very different and we would not be evolved.
  97. How we are they
