Title: Charles Darwin and The Galapagos Islands


1
Charles Darwin
  • The Galapagos Islands

Charles Darwin
  • Charles Darwin the famous naturalist sailed to
    the Galapagos Islands in the HMS Beagle in 1831.
  • Thirty years later he published his Theory of
    Evolution, one of the most revolutionary ideas
    science has ever known.

3
  • On December 27, 1831, the HMS Beagle launched its
    voyage from U.K. with Darwin in tow.
  • Darwin had the unique opportunity to closely
    observe principles of botany, geology and
    zoology.

Research on tortoise at Galapagos
  • Adaptation in the carapace as per habitat.
  • Species living in habitat with food(grass) at low
    level had round carapace and short neck.
  • Those living in area with food(grass) at height
    had long neck and backed carapace.

5
  • Research on Finches

6
  • Darwin discovered that Galapagos finches have
    thirteen different kinds of beaks.
  • The size and shape of the finches beaks was due
    to their adaptation to a particular environmental
    niche.
  • Stated two theories from the observations.

7
The Theory of Evolution
  •  A species is a population of organisms that
    interbreeds and has fertile offspring.
  • Living organisms have descended with
    modifications from species that lived before
    them.

8
Darwin and Natural Selection
  • More organisms are produced than can survive
    because of limited resources.
  • Organisms struggle for the necessities of life
    there is competition for resources.

9
  • Individuals within a population vary in their
    traits some of these traits are heritable.
  • The advantageous trait is being carried to next
    generation.

10
  • More about Galapagos Island
  • Ecuador Government established Charles Darwins
    Research Station at Galapagos.
