How did he come up with his theory? 7. What did his travels reveal? 8. What did he observe? 9. Why was his voyage important?

4. What is Biological Diversity? Earth has millions of organisms of every imaginable shape, size, and habitat. The variety and abundance of species that make up a biological community is called biodiversity..

5. The Big Question is … How did all these different organisms arise? How are they related How are they related?

6. What is “evolution”? Evolution means change over time. What causes this change? What causes this change?  Mutations - a permanent change in the DNA sequence of a gene

7. What is “evolution”? Evolution means change over time. What is an adaptation? What is an adaptation?  An adaptation is a feature that is common in a population because it provides some improved function  An adaptation is a feature that is common in a population because it provides some improved function.

8. What is the Theory of Evolution”? Change in the gene pool of a population from generation to generation by such processes as mutation, artificial/natural selection, and genetic drift.

9. 1785 James Hutton postulated that the earth was formed by an ancient progression of natural events, including erosion, disruption, and uplift. Early 1800’s George Cuvier suggested that the earth was 6,000 years old- based on his calculations. 1830 Charles Lyell published evidence pushing the age of earth back several million years. 1838 Charles Darwin starts to theorize on evolution. 1858 Alfred Russell Wallace publishes similar theory of evolution. Timeline of Theory

10. Charles Darwin Who is considered the Father of Evolution? The first person to explain the cause of biological diversity

11. How did Darwin come up with his Theory of Evolution?

12. 1.Charles Darwin (1809-1882) Sailed around the world 1831-1836 Darwin went on an around-the-world trip on the HMS Beagle and traveled to the Galapagos Islands.

13. H.M.S Beagle Route

14. What did Darwin’s Travels reveal? The diversity of living species was far greater than anyone had previously known! Species of different origins had similar structures These observations led him to develop the theory of evolution!!
