  1. Welcome! The Topic For Today Is Evolution!

  2. Your Topic

  3. Theory of Evolution: 200 • Question: • The process whereby modern organisms have descended from ancient common ancestors • Answer • What is the Theory of Evolution? Back

  4. Theory of Evolution: 400 • Question: • He proposed that giraffes stretched their necks in order to reach higher foliage and so their children had longer necks too • Answer • Who is Lemark Back

  5. Theory of Evolution: 600 • Question: • Process by which individuals better suited to their environment can survive and reproduce most successfully. • Answer • What is Natural Selection or Survival of the Fittest Back

  6. Theory of Evolution: 800 • Question: • A process in which humans choose the most desirable traits of a population for breeding purposes • Answer • What is Artificial Selection Back

  7. Theory of Evolution: 1000 • Question: • Individual differences within a population • Answer • What is Variation? Back

  8. Evidence for Evolution: 200 • Question: • This was when Dino’s went extinct • Answer • 65 million years Back

  9. Evidence for Evolution: 400 • Question: • Structures that have similar embryological origin and structure but are adapted for different purposes • (ex: human arm and batwing) • Answer: • Homologous structures Back

  10. Evidence for Evolution: 600 • Question: Body parts that have become very reduced over time • Answer: • What are Vestigial structures Back

  11. Evidence for Evolution: 800 • Question: • The early stagesof development in organisms in which there are many similarities among different species. • Answer • What is Embryology? Back

  12. Evidence for Evolution: 1000 • Question: • These are four pieces of evidence for evolution • Answer • What are fossil record, embryology, homologies, biochemistry Back

  13. DNA and Mutation: 200 • Question: • This is what DNA stands for • Answer • What is deoxyribonucleic acid Back

  14. DNA and Mutation: 400 • Question: • DNA is made of these 3 components • Answer • What are deoxyribose/pentose sugar, phosphate group, nitrogen-containing base Back

  15. DNA and Mutation: 600 • Question: • These two nucleotides prefer each other’s company over any other • Answer • What are A=T /A=U or C=G Back

  16. DNA and Mutation: 800 • Question: • Mutations in DNA can be one of 3 things: • Answer • What are Neutral, Positive, Negative • Addition, Deletion, Inversion, Translocation, etc. • Missense, Nonsense, Neutral Back

  17. DNA and Mutation: 1000 • Question: • Small populations with small gene pools are likely to experience this leading to fixation of alleles • Answer • What is Genetic Drift Back

  18. Speciation: 200 • Question: • A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding • Answer • What is a species Back

  19. Speciation: 400 • Question: • The “profession” and habitat of an organism • Answer • What is a Niche? Back

  20. Speciation: 600 • Question: • The process whereby new species emerged from a primary species • Answer • What is speciation? Back

  21. Speciation: 800 • Question: • Mountain ranges or streams may lead to this type of speciation • Answer • What is allopatric or speciation by geographical isolation Back

  22. Speciation: 1000 • Question: • This occurs as new species evolve to fill novel ecological niches in new habitat • Answer • What is adaptive radiation? Back

  23. Potpourri: 200 • Question: • A phenomenon in which species suddenly vanish. • Answer • What is a Mass Extinction? Back

  24. Potpourri: 400 • Question: • This model of evolution suggests that there were rapid changes in organisms followed by periods of stasis • Answer • What is punctuated equilibrium Back

  25. Potpourri: 600 • Question: • RNA contains this nucleotide instead of Thymine • Answer • What is Uracil Back

  26. Potpourri: 800 • Question: • This was the ship Darwin sailed on • Answer • What is the HMS Beagle Back

  27. Potpourri: 1000 • Question: • Courtship dances and extravagant feathers may seem like poor adaptations but my be due to this • Answer • What is sexual selection? Back

  28. Final Jeopardy • Question: • This contemporary of Darwin had a similar idea to the Theory of Evolution and his impending publication spurred Darwin to publish “On The Origin of Species” • Answer • Who is Alfred Russel Wallace Back
