  1. Devil of a Disease Case Study Slides 2012

  2. Goals for the Day • Put the ideas of the theory of Evolution by Natural selection to work. • Be able to write a testable hypothesis & experiment to go along with it. • Understand the importance of genetic variability

  3. Question of the Day What needs to be present in a population for evolution by natural selection to occur? Hint: We talked about ways we increase & decrease this

  4. Case Study:Devil of a Disease

  7. Immune System • Self vs. Non-self

  8. Goals for the Day • Be able to evaluate possible consequences of different conservation actions for species. • Put the ideas of the theory of Evolution by Natural selection to work. • Understand and be able to describe the importance of genetic variability

  9. Question of the Day If natural selection needs variation to act on, what is the problem with genetically similar individuals.

  10. Genetic Diversity • Genetic Drift – changes in the frequency of a gene in a population due not to mutation or natural selection, but due to chance. • Founder effect – small numbers of individuals are isolated from a larger population

  11. Genetic Diversity Population/Genetic Bottleneck • an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing, and the population is reduced by 50% or more, often by several orders of magnitude.

  12. Genetic Diversity Population/Genetic Bottleneck • Population bottlenecks increase genetic drift, due to reduction in population size. • They also increase inbreeding due to the reduced pool of possible mates

  13. Case Study:Devil of a Disease

  14. Part III Proposals • Genetic Engineering • Separate devils with tumors • Find a cure • Breed healthy or sick individuals in captivity • Semi-wild fenced off enclosures for populations • Kills devils with tumors

  15. Part III Proposals • Genetic Engineering Pros Cons

  16. Part III Proposals • Separate devils with tumors Pros Cons

  17. Part III Proposals 3. Find a cure Pros Cons

  18. Part III Proposals 4. Breed healthy or sick individuals in captivity Pros Cons

  19. Part III Proposals 5. Semi-wild fenced off enclosures for populations Pros Cons

  20. Part III Proposals 6. Kill devils with tumors Pros Cons

  21. You are the manager! Write a ½ page explanation of which strategy or combination of strategies you would employ and why. • Genetic Engineering • Separate devils with tumors • Find a cure • Breed healthy or sick individuals in captivity • Semi-wild fenced off enclosures for populations • Kills devils with tumors
