1. Evolution
By David Caldwell

2. Lesson Objective
I chose this topic because I’ve always been interested in why there is such a gap between what we know about evolution and what people believe.

3. Lesson Objective
Only 40% of people accept the science of evolution, when we have more evidence to support it than we have evidence that the Roman Empire existed

4. Lesson Objective
After completing this lesson students will understand three things
What evolution is and what it is not
What a theory is
Examine the evidence of evolution.

5. Background
Asked how and why are there so many species of animals/plants and discovered common ancestry.
The theory of evolution has passed every conceivable for 150yrs

6. Background
Today Evolution is the foundation of modern biology and the best explanation we have for the diversity of life.

7. What Evolution is Not... It does not say how life began
It does not say how the universe started.
It says nothing about whether or not there is a god or gods.

8. Evolution explains change in species over time...
What is Evolution?
Evolution explains change in species over time...
Common Ancestry

9. Did Humans come from monkeys?
NO!
We evolved from a common ancestor...like cousins

10. Just a theory?
If someone says: “evolution is just a theory:..they are not using the word (theory) as it is used in science.

11. What is a scientific theory?
A scientific theory is a well substantiated explanation for a set of solid facts.
Theories explain facts and include Laws.
EX: the theory of gravity explains the facts of the laws of attraction.

12. Other Scientific Theories
Theory of Gravity
Germ Theory of Disease
Atomic Theory
Big Bang Theory

13. Why is Evolution so important?
Evolution is the foundation of all modern biology and medicine.
Understanding evolution has led to to breakthroughs in medicine as well as inform our knowledge of our past.

14. Basics of the Scientific theory of Evolution
Species change over time. This is evolution.
All species have a common ancestor
Natural selection is the mechanism for change

15. Is Evolution True
More evidence supports evolution than any scientific theory.
If we made a comparison to history, we have more evidence for evolution than we do that the Roman Empire existed.

16. Evidence for Evolution...

17. Evidence for Evolution

18. Evolution...the fossil record
Similar Structures

19. Evidence-Fossils
Changes over time

20. Evidence-DNA

21. Evidence-Predictions
building strong theories in science is about evidence and making testable predictions. (we can predict what we should find before we find it)

22. Testable Predictions...
Based on what we now know, scientist can predict what type of fossil they will find in a location, dig for it and find it. this is how strong the evidence is and the ability to predict.
