1. Sponge
How are these items similar?
How are they different?
Answer: All are clothing, but
They all perform a different function.
Darwin noticed the same thing with the
Galapagos finches.

2. Sponge Describe the difference between Selective Breeding
And Natural Selection.

3. How Does Evolution Happen?

4. In 1831, Charles Darwin, a 21 year-old naturalist, boarded a
British naval ship, HMS Beagle, and began a voyage
Around the world.
Darwin observed that the animals and plants on the
Galapagos Island were similar but not identical
to plants and animals on the nearby South American
mainland.
Example: he noticed the finches on the mainland
Ecuador differed slightly from the finches on the
Galapagos Islands.

6. Darwin thought about how farmers would selectively
Produce farm animals with certain traits
(selective breeding).
He thought wild animals and plants could change in a
Similar way but that the process would take much
Longer because variations would be due to chance
(Natural Selection).

7. I. Four steps of Natural Selection
a. overproduction
b. Genetic Variation
c. Struggle to Survive
d. Successful Reproduction

8. II. Formation of a New Species
a. Separation
b. Adaptation
c. Division

9. Vocabulary 1. Selective Breeding- Breeding of organisms that have a
Certain desired trait.
2. Trait-
Distinguishing qualities that can be passed
From one generation to another.
3. Natural selection-
The process by which organisms
With favorable traits survive and
Reproduce at a higher rate than
Organisms without the favorable
Trait.

10. Sponge
Describe a situation where natural selection is
Observed.
