Across
- 3. mechansism of evolution caused by changes in DNA
- 5. mechanism of evolution associated with migration into or out of a population into another population
- 7. form of genetic drift;random change dut to chance;usually caused by natural disasters
- 9. the process by which new species are created through evolution
- 10. measure of the ability of a species to survive and reproduce
- 14. mechansism of evolution caused by crossing over and sexual reproduction
- 15. structures that are similar is appearance;suggest common ancestry
Down
- 1. structures that are present but no longer used by modern organisms;suggest common ancestry
- 2. mechanism of evolution associated with differential reproductive success
- 4. a change in a population's gene pool over time
- 6. form of genetic drift;occurs when a small population of a species establishes a new population
- 8. inherited trait that allows an organism to survive and reproduce
- 11. differences found in individuals
- 12. the set of genes in a population;can change over time
- 13. evolution of new species by slow small genetic changes over time
