Final Jeopardy

2. Theory of Evolution - $100 Who developed the theory of evolution?
Charles Darwin

3. Theory of Evolution - $200 What is evolution?
Cumulative changes in groups of organisms through time

4. Theory of Evolution - $300 What is natural selection?
Some organisms are more adapted to survive in an environment than others. Survival of the fittest.

5. Theory of Evolution - $400 What is artificial selection?
The process of directed breeding to produce offspring with desired traits, also known as selective breeding

6. Theory of Evolution - $500
What are the four principles of natural selection?
Variation, Heritability, Overproduction, Reproductive Advantage

7. Evidence of Evolution - $100
How do fossils show evidence of evolution?
They can show how ancient species are similar to current species

8. Evidence of Evolution - $200
What are homologous, analogous, and vestigial structures?
Homologous – visually similar, different functions
Analogous – visually different, same functions
Vestigial – Reduced form of functional structures in other organisms

9. Evidence of Evolution - $300
What is the difference between derived and ancestral traits?
Derived – newly evolved features
Ancestral – more primitive features that do appear in ancestral forms

10. Evidence of Evolution - $400
How do embryos show evidence of evolution?
They are visually similar in early states. Vertebrae exhibit homologous structures during select phases of development.

11. Evidence of Evolution - $500
List all three types (in book) of adaptations
Camouflage
Mimicry
Antimicrobial resistance

12. Mechanisms of Evolution - $100
What is genetic drift?
Any change in the allele frequency of a population that results from chance

13. Mechanisms of Evolution - $200
What is the difference between the founder effect and the bottleneck effect?
Founder – a small sample of the population is separated from the rest of the population
Bottleneck – a population declines to a very low number then rebounds

14. Mechanisms of Evolution - $300
What is the difference between stabilizing, directional, disruptive, and sexual selection?
Stabilizing – eliminates extreme versions of a trait
Directional – increases the extreme versions
Disruptive – splits a population into two groups, both with extreme versions of the trait
Sexual – based on the ability to attract a mate

15. Mechanisms of Evolution - $400
What is the effect of a mutation on a population?
It would cause a change in allele frequency, and violates genetic equilibrium. Could be beneficial or harmful

16. Mechanisms of Evolution - $500
What are the five conditions required for a population to be in genetic equilibrium (Hardy-Weinberg Principle)?
Large population
No immigration or emigration
Random mating
No mutations
No natural selection

17. Patterns of Evolution - $100
What pattern of evolution did the finches show on the Galapagos islands?
Adaptive radiation

18. Patterns of Evolution - $200
What is coevolution?
When many species evolve in close relationships with other species

19. Patterns of Evolution - $300
What is it called when unrelated species evolve similarly?
Convergent evolution

20. Patterns of Evolution - $400
What is gradualism?
The theory that evolution occurs in small steps.

21. Patterns of Evolution - $500
What is it called when rapid spurts of genetic change cause species to diverge quickly?
Punctuated Equilibrium

22. Speciation and Reproductive Isolation - $100
What is speciation?
The formation of new and distinct species in the course of evolution

23. Speciation and Reproductive Isolation - $200
What kind of speciation occurs when a physical barrier divides a population into two or more populations?
Allopatric speciation

24. Speciation and Reproductive Isolation - $300
What is sympatric speciation?
When a species evolves into a new species without a physical barrier

25. Speciation and Reproductive Isolation - $400
What is the difference between prezygotic and postzygotic isolation mechanisms?
Prezygotic – occurs before fertilization
Postzygotic – occurs after fertilization

26. Speciation and Reproductive Isolation - $500
What are the five ways reproductive isolating mechanisms occur?
Geographically, habitat, behaviorally, gametically, temporally

27. Final Jeopardy
What is a measure of the relative contribution that an individual trait makes to the next generation?
Fitness
