Across
- 2. non-fuctional genes
- 7. group of organisms that can successfully interbreed and produce viable, fertile offspring
- 8. the process of biological change in populations over time
- 9. species that exist only in one geographic region
- 10. study of prehistoric life through the fossil recorded
- 12. a feature that allows an organism to better survive in its environment
- 15. study of chemical processes in living things
- 17. organisms with the best traits will live longer and reproduce more than others, causing changes in the population over time by acting on traits that are heritable
- 18. a measure of how well you can survive in the environment
- 19. study of embryo development
- 20. the combined alleles of all individuals in a population
- 21. preserved remains of organisms
Down
- 1. the selection of traits isn't necessarily good for the survival of fitness, but without them, you can't pass on your genes at all because you cannot reproduce
- 3. movement of genes into/out of a population
- 4. random change in the frequency of alleles in a population over time
- 5. the study of the geographic distribution of plants and animals
- 6. evolution on a large scale affects changes in species across populations
- 11. when there are no changes in allele frequencies in a population over time
- 13. a type of divergent evolution occurring on a small scale over a shorter period of time
- 14. evolution on a small scale affecting a single population
- 16. the study of the form of living things
