Energy in Plants and Animals

5. An area that Darwin explored and developed his theory of evolution
6. Darwin’s observation of animals that no longer exist but look similar to current animals. This made him wonder if things have been changing slowly over time
7. A trait that helps the organism survive and reproduce
13. Traveled the world on the Beagle and developed the theory of evolution
14. We look the same in the womb because we came from a common ancestor
16. Members of the same species fight for the same resources (directly or indirectly)
17. More offspring produced than can survive

1. Show that organisms in the past were slightly different from organisms today.
2. A slight change in DNA (beneficial or detrimental)
3. Anatomical structures that look similar due to a shared ancestor
4. These similarities show how our heart and arms look like hearts and arms of other species.
8. Darwin’s observation of slight differences in animals, like the beaks of the finches. It made him wonder if they were related or if they had a common ancestry
9. The theory that species make small changes over time
10. The process by which individuals that are better adapted to their environment are more likely to survive and reproduce
11. Species change over many generations to become better adapted to their environment
12. Similarities with these structures indicate how we are genetically similar to other species.
15. Different variations are advantageous in different environments
