Evolution

3. Harmless species resembles a harmful one.
6. Believed in "divine institution".
7. Small, graduated steps over time
8. How many pairs of chromosomes are in humans?
9. Embryos of many animals with backbones that are similar.
10. Occurs when a new population is established by a very small number of individuals from a larger population.
12. Proposed that natural selection was the mechanism by which evolution was taking place.
14. Appendix in humans is an example of what structure?
15. Random mating and large populations are examples of this principle.
19. Accumulation of differences between groups which can lead to the formation of new species.
20. Can be harmful, helpful, or neutral.
22. Individuals at both of the extremes of a trait are both more fit and are favored over the average individuals in the population.
23. Individuals at one end of the curve have higher fitness and are favored more than individuals in the middle or at the other end.
24. Average individuals in the population have higher fitness and are favored.

1. Believed in the use and disuse of particular organs.
2. A walking stick bug is an example of this type of adaptation.
4. Provides a record of early life and evolutionary history
5. Abrupt changes causing diversion quickly
11. Unrelated species evolve similar traits in environments that are geographically far apart, but have similar ecology and climate.
13. This is often measured as the number of reproductively viable offspring that an organism produces in the next generation.
16. What is a trait shaped by natural selection called?
17. Founder Effect and Bottleneck are examples of this mechanism of Evolution.
18. The heredity changes in groups of living organisms over time driven by genetic diversity.
21. Structural features that can be similar in arrangement in function, or in both.
25. Result of this is a small population with decreased genetic variability inbreeding with itself.
