1. Study Guide Review!!!!
Also use the Vocabulary Review PPT to help understand these important evolution concepts.

2. Charles Darwin
Naturalist who traveled the HMS Beagle to the Galapagos Islands and discovered finches…
The finches all had similarities but different beaks due to the different types of foods they ate.
The finches changed because of speciation.

3. Evolution Inherited changes in a population over time.
Evidence that supports evolution:
Similar skeletal structures
DNA
Embryonic structures

4. Adaptations!
Structures and behaviors that help an organism find food, protection, and move from place to place.
Examples:

6. Theory of Evolution? NATURAL SELECTION! Over production
Genetic Variation – organisms are genetically diverse because of mutations!
Struggle to Survive
Successful Reproduction

7. Natural Selection
Who blends in? Who stands out?

8. Speciation Reasons for a population to separate…
Mountain range forming
Canyons forming
Lake forming
Islands separating or forming

9. Selective Breeding
Organisms with favorable traits being bred for those specific traits.

10. Selective Breeding vs. Natural Selection
Natural selection occurs when population members with advantageous traits are able to survive and reproduce. They pass on their advantageous traits to their offspring. Selective breeding occurs when humans breed individuals with desirable traits in order to create offspring with the same desirable traits.

11. Steps of Natural Selection
Overproduction
Genetic Variation
Struggle to Survive
Successful Reproduction
