Darwins expedition
  • By Diamond
  • Brown

3
Darwins observations
  • Darwin observed the diversity of living things.
  • the remains of ancient organisms.
  • And the characteristics of organisms living on
    the Galapagos islands.

4
Diversity
  • He was amazed by the diversity of all the
    different animals
  • There were many of the same species of animals
    with diff. characteristics than the other
    organism that are the same species but have diff.
    characteristics.
  • Species- a group of similar organisms that can
    mate with each other produce offspring
  • He found many diff. species of animals in the
    Galapagos islands

5
Fossils
  • Fossils- the preserved remains or traces of an
    organism that lived in the past

6
Evolution
  • By Gabby Lucarelli Raelyn Dawson

7
Evolution
  • The gradual change in species overtime is called
    evolution.

8
Darwin's reasoning
  • Darwin really wanted to understand the different
    variation and life styles of organisms on the
    Galapagos islands.
  • Darwin's reasoned that plants or animals that
    arrived on the Galapagos islands faced conditions
    that were different from the conditions faced on
    the main lands.

9
Darwins Theory
  • Darwins ideas are often referred to as the
    theory of evolution.
  • A scientific theory is a well-tested concept that
    explains a wide range of observatons.

10
Galapagos Organisms
  • By Eric Rudary, Tyler Castro, Leny Bykov, Leo
    Held, Alexis Bearss

11
  • Darwin found that many of the birds on the
    Galapagos Islands resembled those on the mainland.

12
  • Darwin hypothesized that a small number of
    different plant and animal species had come to
    the Galapagos Islands from the mainland.

13
  • Darwin noticed many differences among organisms
    as he traveled from one Galapagos Island to the
    next.

14
  • The beak shapes of the different finches on the
    Galapagos Islands are an example of an adaptation
    (a trait that helps an organism survive and
    reproduce).

15
Natural Selection
  • By
  • Angela Faranda
  • Ariana Ehasz

16
Natural selection is the process by which
individuals that are better adapted to their
environment are more likely to survive

17
Overproduction

When too much offspring are produced there is not
enough resources food, water, and living space-
for them all. If newly hatched insects survived,
they would soon crowd out all the other plants
and animals.
18
Variations
  • A difference between two individuals of the same
    spices.

19
Competition
  • Where animals compete for food, space, or water
    to survive. Its mostly indirect than violent.

20
Selection
  • Selection is the process were animals with an
    adaptation reproduce a lot more and over the time
    of many different generations.

21
Environmental Change
  • Environment Change is when the environment
    changes and can kill off many members of a
    species. Then only the animals with a special
    adaptation survive and live on to reproduce more
    of the animal. The offspring then gets the
    adaptation.

22
Genes And Natural Selection
  • Variation in the genes is what causes natural
    selection. The animal with the gene is more
    likely to have offspring which will in turn get
    the special gene.
