  1. POP QUIZ! I. What are the 5 conditions that must remain constant for a population to be in evolutionary equilibrium? (try to name at least 4 of them)

  2. In this species, yellow (120) is dominant to blue (80).

  3. Using this population of butterflies and the Hardy- Weinberg law: • Calculate p and q for this population. • 2. What do p and q represent? • 3. Describe the probable genotypic ratios of this population. (what are the frequencies of each of the following genotypes: BB, Bb and bb.) • How many of the yellow butterflies are most likely BB and how many are Bb? • 5. Why is this information important to evolutionary biologists? In this species, yellow is dominant to blue. 120 yellow, 80 blue

  4. 6. If a scientist returns to this population each year and observes that the population continually has the same frequencies of p & q, what is most likely occurring (or not occurring) in this population? • 7. Why?

  5. (Ch22) Homologous & Analogous structures

  6. Analogous structures are common structures adapted to common environments, but not evolutionarily (genetically) related. • This is _________ evolution.

  7. Analogous structures are common structures adapted to common environments, but not evolutionarily (genetically) related. • This is convergent evolution.

  8. “It is the population, not the individual, that evolves.” • What is biological “fitness”?

  9. Some examples of the results of Sexual selection

  10. What is the biological definition of a species?

  11. Fig 24.04

  12. Is this allopatric or sympatric speciation?

  13. Is this allopatric or sympatric?

  14. What is MACRO-EVOLUTION? • And what are some ways in which it can occur?

  15. Which terms belong together? (make two groups) 1. Homologous structures 2. Analogous structuresdivergent evolution adaptive radiation convergent evolution • Which terms belong together? (make two groups) gene flow genetic drift bottleneck immigration emigration founder effect

  16. What is evolutionary ‘fitness’? • If it is determined that an allele reduces fitness, what does that mean?And • How is it determined that fitness is reduced?

  17. What is the complete scientific classification of humans? AnimaliaChordataMammaliaPrimateHominidaeHomo sapiens

  18. Kingdom • Phylum • Class • Order • Family • Genus • Species • Homo sapiens • Escherichia coli

  19. Phylogeny&Cladistics

  20. Phylogeny

  21. Did dogs evolve from cats? • OR • Did cats evolve from dogs? • OR • Neither?
