- 2. One of the first scientists to disprove spontaneous generation by showing that flies come from other flies and are not created from meat
- 4. type of evolution in which the development of similar structures in different ancestral lines due to environmental pressures; unrelated species acquire similar traits
- 6. structures in different species that have similar functions but the internal structures are different; gives evidence of convergent evolution
- 8. Any physical characteristic or behavior that helps an organism to better survive
- 9. type of structure in different species that have internal structures even though they may have different functions ; gives evidence of divergent evolution
- 10. Diagram that shows relationships among organisms based on evolved adaptations or characteristics
- 12. Creating more offspring than can be supported by the environment
- 14. Existing with oxygen
- 15. Existing without oxygen
- 16. type of evolution in which accumulation of differences that results in the formation of different species from a common ancestor; related species acquire different traits
Down
- 1. “The father of evolution” who believed that a process called natural selection explains how organisms evolved over time
- 3. Theory that explains the origin of mitochondria and chloroplasts in eukaryotic cells
- 5. Theory that states that organisms have changed gradually over time to form new kinds of organisms (or new species)
- 7. A scientific law that states that living organisms come only from other living organisms
- 11. The idea that organisms have adaptations that allow them to be best suited for the environment where they will survive to reproduce
- 13. Structures that have no useful purpose
