1. Evidence for Evolution Video

2. Warm up- Pop Quiz
Who is this man? Hint- he wrote The Origin of Species
What journey changed his life?
Where did he go?
What did he observe?
What is evolution? Why is it important

3. Warm up What is evidence for evolution? List four examples?
What is comparative anatomy?
How are genetics used to support evolution?

4. Species- group of organisms, two individuals can create fertile offspring

5. Hierarchy of Biological Organization

6. Vocabulary Evidence of evolution
Similar organisms share a common ancestor.
Evidence of evolution
Fossil record
Comparative anatomy- differences and similarities between living things
Anatomy- study of the structure of organisms and their parts
Embryology- study of how animals development before birth
Molecular Biology (DNA)- scientists compare DNA between animals to see how closely they are related
Geographic Distribution

7. Earliest placental mammal- 65 million years ago!
Common Ancestors
Earliest placental mammal- 65 million years ago!

9. Fossil Record Information about past life Structure of organisms
What they ate
What ate them
What environment they lived in
Time period they lived in

11. Comparative Anatomy
Humerus
Ulna/radius
Carpal
Metacarpal
Phalanges

12. Anatomical Structures
Homologous structure- same anatomy, different function
Analogous structure- different anatomy, same function
Vestigial structure- remnants from a common ancestor, no longer used

13. Homologous Structures

14. Analogous Structures

15. Vestigial Structures

16. Embryology
The early stages, or embryos, of many animals with backbones are very similar.

17. Genetics

18. Geographic Distribution
Shared a common ancestor, adapt to where they live
island species most closely resemble nearest mainland species
Population can show variation from one island to another

20. Gene Pool-  genes, or genetic information, in any population, usually of a particular species.

22. Genetic Drift

23. 4 Principals of Natural Selection/Evolution
Individuals in a population have VARIATIONS
Variations are INHERITED
Not all offspring produced can survive
Variations that increase reproductive success will have a greater chance of being passed on
