Nathan Chua Evolution

4. organisms that evolved similar structures due to environment, not ancestry
6. the study of prehistoric life
8. the idea that species change over time and will be different from their ancestors
10. the process of biological change that makes descendants different from their ancestors
20. similar characteristics resulting from common ancestry
24. the extinction of a species at a slow rate (climate change)
25. the forming of a new species by evolution from pre-existing species
26. the study of the structure of organisms
27. the study of prehistoric life
28. non-random mating

1. a group of individuals of the same species within a community
2. when unrelated species evolve similar traits b/c they live in similar environments
3. the preserved remains of plants and animals
5. a feature that allows an organism to better survive its environment
7. all of the genes present in a reproducing population
9. any movement of individuals and/or genetic material they carry, from one population to another (migration)
11. the process through which populations of living organisms change due to fitness and environment
12. where living things are located
13. bursts of change followed by periods of stability
14. a group of organisms that can reproduce with one another
15. two organisms changing in response to each other forming a specialized relationship
16. the study of the chemical processes in organisms (DNA and Amino Acids)
17. the study of the embryonic development of organisms
18. where species sharing a common ancestry become more distinct due to speciation
19. slow changes in a species over a long period of time
21. a random change in the DNA of a cell
22. structures with little or no function to the organism
23. the extinction of an organism(s) due to a catastrophic event that changes the environment suddenly
