1. D ARWIN : T HE M AN B EHIND THE T HEORY OF E VOLUTION 7 th Grade Life Science Mr. P

2. C HARLES D ARWIN : T HE Y OUTH He was born Feb. 12 1809 in England. He was the son of a well-known physician. Darwin was kicked out of school because of his bad grades Darwin’s mother died while he was 8 years old

3. C HARLES D ARWIN : T HE M AN He dropped out of medical school because he could not stand the sight of blood He then pursued a life in the Church, but did not find it interesting He became interested in studying beetles and reading scientific findings

4. C HARLES D ARWIN : T HE SCIENTIST Charles Darwin sailed aboard the HMS Beagle. He was the naturalist aboard the ship, which sailed around the world. He was horribly sea sick the entire trip He stopped anywhere he could and made amazing discoveries

5. C HARLES D ARWIN : T HE S CIENTIST He kept careful notebooks of the voyage and his findings

6. C HARLES D ARWIN : T HE S CIENTIST

7. C HARLES D ARWIN : H IS V OYAGE He made several stops, but he is most famous for his findings from an island off the coast of Ecuador named the Galapagos islands.

8. G ALAPAGOS

11. C HARLES D ARWIN : T HE S CIENTIST On the Galapagos, he found diverse organisms, such as finches, which had different beak sizes for the different types of food they eat.

13. F INCHES ….C OMMON A NCESTOR ?

14. C HARLES D ARWIN : T HE S CIENTIST He also found different species of Tortoises, which had different neck sizes to reach different food sources.

15. C HARLES D ARWIN : T HE S CIENTIST Once home, he looked at the data he collected and came up with his theory of Natural Selection in his famous book Origin of Species.

16. C HARLES D ARWIN : T HE S CIENTIST Darwin also looked at pigeon breeding, which is a form of Selective Breeding and is the basis for how we breed dogs.

17. S ELECTIVE B REEDING : D OGS

18. C HARLES D ARWIN : T HE L EGACY Darwin’s theory of natural selection is the basis for modern biology and is the foundation of how we study nature. REMEMBER : Evolution is CHANGE OVER TIME

19. T HE INSPIRATION While in the Galapagos, Darwin saw that the tortoises showed variation of characteristics.

20. T HE INSPIRATION Darwin saw that animals adapted to their environment in the Galapagos.

21. T HE T HEORY Natural Selection is the process for which individuals with traits that are better suited for the environment are more likely to survive longer and reproduce more successfully than those individuals without these traits

22. N ATURAL S ELECTION Adaptations are the inherited traits that increase an organism’s chance of surviving and reproducing in a particular environment.

23. T HE MAIN OUTCOME …. The outcome of natural selection is diversity of life
