Transcript of "Module 12 Lesson 1"

  1. 2. Theory Of Spontaneous Generation or Abiogenesis <ul><li>This is an incorrect theory that was believed for many centuries. </li></ul><ul><li>It stated that living things come from nonliving things. </li></ul><ul><li>Aristotle said that it explained how life got here. </li></ul><ul><li>A variety of experiments were performed to disprove it. </li></ul>Redi proved that maggots come from flies, not meat. http://www.slic2.wsu.edu:82/hurlbert/micro101/images/maggots.gif
  2. 3. Biogenesis <ul><li>After many years it was concluded that life comes from life. Pasteur’s experiment helped to disprove spontaneous generation. facstaff.gpc.edu/.../Microbial%20World.htm </li></ul>
  3. 4. Oparin’s Organic ( Primordial)Soup Theory <ul><li>He believed that Earth’s early atmosphere had the chemical elements necessary to create organic compounds. These elements combined due to static electricity and sunlight and made the first organic compounds. He hypothesized that these organic compounds were the building blocks of the first life forms. </li></ul><ul><li>His theory was tested out by Stanley Miller in a lab where he was capable of creating amino acids. </li></ul>
  4. 5. Microevoultion <ul><li>Small Changes in a population over time. </li></ul><ul><li>http://blog.nature.org/wp-content/uploads/2009/02/darwins_finches_by_gould.jpg </li></ul>
  5. 6. Macroevolution <ul><li>Large changes over time. </li></ul><ul><li>Bacteria  Man </li></ul><ul><li>The first organisms were probably </li></ul><ul><ul><li>Prokaryotic ( without a nucleus) </li></ul></ul><ul><ul><li>Unicellular ( one celled) </li></ul></ul><ul><ul><li>Anaerobic( They don’t need oxygen) </li></ul></ul><ul><ul><li>And they probably lived in the ocean. </li></ul></ul>
