1) Which of the following constraints on adaptation tends to affect small, genetically isolated populations and can ultimately lead to the loss of variation over time? a. external factors b. correlated characters c. local vs. global optima d. genetic drift 2) Designating Medium Ground Finches and Large Ground Finches as separate species because, while individuals from each species can mate with each other, these hybrid offspring are typically selected against in nature is based on which of the following ideas? a. reasoning by analogy b. the biological species concept c. the ecological species concept d. parapatric speciation

1.) When a population is split by a physical barrier such as a mountain range, interrupting gene flow: a) they can accumulate genetic differences while separated. b) they will evolve wings to fly over the mountains. c) they will become new species. d) they can evolve into new species over time. 2.) In allopatric speciation: a) populations do not exchange genetic information. b) populations can become reproductively isolated. c) populations are separated by some physical barrier. d) new species arise from within a population with no physical barriers to gene flow.

There are two closely related populations of squirrels living in the Grand Canyon area—one lives on the north rim, the other lives on the south rim. Speciation in these squirrels BEST fits which model? a. dispersive allopatric speciation b. dispersive sympatric speciation c. vicariant allopatric speciation d. vicariant sympatric speciation 2. Factors such as behavioral, temporal, or ecological isolation mechanisms that prevent two closely related sympatric populations from interbreeding can be grouped together and classified as ______________. a. prezygotic isolating mechanism b. postzygotic isolating mechanism c. polyploidy hybrid speciation d. adaptive radiation

Which of the following best characterizes an adaptive radiation? a. Speciation occurs extremely rapidly, and descendant populations occupy a large geographic area. b. A single lineage diversifies rapidly, and descendant populations occupy many habitats and ecological roles. c. Natural selection is particularly intense, because disruptive selection occurs. d. Species recover after a mass extinction.
