1. Evidence of Evolution

2. Evolution  The process by which life has changed over time.  Macroevolution  Microevolution

3. Evolution

4. What are species?  Species literally means ‘kinds’.  We recognize most species by their appearance.

5. Evolution  Taxonomy( systematics) – branch of biology that names and classifies species Carl Linnaeus  Will cover more in Unit 16 (1707–1778), a Swedish botanist, invented the modern system of binomial nomenclature.

6. Evolution  Example  Panthera pardus

7. Population  All the members of a species living in a particular area new variations arise new variations arise these individuals tend to survive these individuals tend to survive This is where evolution This is where evolution occurs ( not indivual)

8. Adaptations  Adaptations are special features that allow a plant or animal to live in a particular place or habitat.  structures, physiology

9. Adaptations  Explain why life is so diverse

10. Evolution  While, evolution is an explanation for the unity of life.  All organisms share the same characteristics of life because they can trace ancestry to the first cell or cells.

11. Evolution  Example: Humans and monkeys share a common ancestor which separated into 2 separate lineages 40 million years ago New world South America migration Old world

12. Today’s Lab  We will look at 2 types of data that supports the hypothesis of common ancestors:  1 ) the fossil record  2) comparative anatomy

13. Don’t forget….quiz next week over evolution
