Critical thinking questions 1. what is the difference between weather and climate in terms of temporal variation? 2. how could spatial heterogeneity be perceived by an organism as temporal heterogeneity? 3. why do we have to consider the mean fitness across all environments when evaluating whether evolving a phenotypically plastic genotype will be favored over a non-plastic genotype? 4. how would the presence of unreliable environmental cues affect the evolution of phenotypically plastic responses to environmental variation? 5. would the frequency of experiencing predator versus no-predator environments affect the evolution of phenotypically plastic traits? 6. if predators reduce prey abundance to very low levels, how might variable predator environments affect the evolution of flexible mating strategies? 7. if a plant can improve its ability to obtain water by growing more roots, why shouldn't the plant always grow more roots? 8. how could you experimentally determine whether migrating birds use day length or temperature as an environmental cue for migration? 9. what is the relationship between correlation and causation? 10. when determining whether to feed on small, medium, or large prey, why should predators evaluate both the energy obtained from each prey item, the abundance of each prey item, and the handling time of each prey item? 7

If you could drill a hole straight to the center of the earth, and keep track of what the hole is going through, youwould find: a) you would go through one sort of material, and then a different, denser material, and then a still-different, still-denser material, because the planet is made of concentric layers, sort of like an onion.b) you would go through one sort of material all the way to the center, because the planet is all mixed up.c) if your hole started at the north pole, you would go through different layers of different materials, but ifyour hole started at the equator, you would go through one sort of material all the way to the center.d) if your hole started at the equator, you would go through different layers of different materials, but if yourhole started at the north pole, you would go through one sort of material all the way to the center.e) you would strike diet pepsi when you got to the center.
