BIOLOGY STORY BOARD

Storyboard Text

  • CHARLES DARWIN PROPOSED THE IDEA THAT IT IS POSSIBLE THAT SIMPLE LIFE FORMS COULD IN FACT COME FROM NON LIVING FORMS.
  • MAYBE LIVING FORMS COME FROM NON LIVING FORMS
  • STANLEY MILLER, A STUDENT AT UNIVERSITY OF CHICAGO, DECIDED TO SIMULATE EALY EARTH CONDITIONS IN A LAB. HE WITH HIS PROFFESOR, HAROLD UREY, OBSERVED THAT LIFE FORMS HAD INDEED GROWN FROM NON LIVING FORMS.
  • I WILL PREFORM AN EXPIRIMENT!
  • ACCORDING TO THE RNA WORLD HYPOTHESIS, RNA WAS THE FIRST THING ON EARTH. RNA THEN WOULD EVOLVE, UNTIL THEY BUILT LIVING ORGANISMS, WHICH WERE SIMILAR TO HOMES OR SHELTERS FOR THEM.
  • RNA EVOLVES THROUGH COPYING. THEY DO THIS BY CONNECTING TO OTHER FORMS OF RNA, AND THEN SPLITTING. THE CHAIN THAT CONNECTED TO THEM WILL THEN CREATE A COPY OF THE ORIGINAL BY CONNECTING TO OTHER PIECES OF RNA, AND FORMING THEM INTO THE SAME AS THE FIRST. MUTATIONS CAUSE RNA TO CHANGE, AND EVOLVE.
  • ACCORDING TO THE ENDOSYMBIOTIC THEORY, EUKARYOTIC CELLS EVOLVED FROM PROKARYOTIC CELLS.
  • SOME LARGER PROKARYOTIC CELLS ENGULFED SMALLER PROKARYOTES. INSTEAD OF GETTING DIGESTED, SOME OF THEM REMAINED IN TACT, AND CONTINUED TO LIVE. THESE ARE BELIEVED TO BE THE ANCESTOR EUKARYOTIC CELLS.
