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