Charles Darwin traveled to the Galapagos Islands in 1831 aboard the HMS Beagle, which led to the formulation of his revolutionary theory of evolution thirty years later. His observations of species, especially finches with varying beak sizes and tortoises with differing shell shapes, highlighted adaptation and competition for resources among living organisms. The Galapagos Islands are now home to a research station established by the Ecuador government, commemorating Darwin's contributions and the unique biodiversity of the region.

1. The Galapagos Islands

2. • 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. • 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.

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

7. • 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. • 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. • 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.
