Charles Darwin

Slides describes the journey of great naturalist and scientist Charles Darwin and his research at Galapagos islands.Darwin visited Galapagos islands during 18th century on his famous voyage. The main aim of the voyage was to study zoology and different animal species in each continent. While his stay at Galapagos Darwin observed species of Giant tortoises and the Finches( also called as Darwin Finches in honor of his work). He found that there was difference in the appearance in animals of the same species relative to their habitat. This research helped Darwin to deliver the famous Theory Of Evolution. Ecuador Government established Charles Darwin Research Center at Galapagos Islands in honor of his work

  1. Charles Darwin & The Galapagos Islands

  2. 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.

  4. 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 Darwin’s Research Station at Galapagos. • The place is famous for Darwin’s name and the Giant Tortoise and the natural beauty.
