A small number of animals moves away from a large ancestral population on the continental mainland and colonizes an island. Which of the following is likely to occur? A. Genetic diversity will decrease on the mainland, because of a population bottleneck. B. Alleles that were more rare on the mainland are likely to become more common on the island, because of the founder effect. C. Genetic diversity will be lower on the island than the mainland, because of the founder effect. D. Mutations rates will increase on the island, in response to selection pressures in the new environment.

Scientists are studying two populations of the same species of sea turtle. One population is quite small, with only 18 individuals, and the other is much larger, with 147 individuals. If a genetic factor such as a mutation were introduced to both populations at the same time, what could scientists predict about the impact?
The three beetle species live in the same ecosystem, and they likely evolved from the ancestral species that colonized the region. Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B. The ancestral species randomly diverged into three species before colonization and then colonized the regions that best suited their new adaptations. C. After colonization, small groups separated from the rest of the ancestral species and developed different adaptations that helped them survive and reproduce. D. After colonization, the large group interbred until they developed enough neutral genetic mutations for speciation to occur.
Species that are more vulnerable to certain risk factors are more likely than others to become extinct. For example, species with a unique lineage, such as the giant panda, are likely to be at severe risk of extinction.a. Should our limited resources for species protection be focused on species that are at the highest risk of extinction?b. Do you support the idea that high-risk species may be less successful products of evolution and should not receive extraordinary protection?
One way to prevent a small population of a plant or animal species from going extinct is to deliberately introduce some individuals from a large population of the same species into the smaller population. In terms of the evolutionary mechanisms discussed in this chapter, what are the potential beneﬁts and drawbacks of transferring individuals from one population to another? Do you think biologists and concerned citizens should take such actions?
Why are humans so genetically similar within our species? A. Because humans evolved in multiple locations around the world at different times. B. Because humans evolved in one location (Africa) and we have existed as a species for very long time. C. Because humans evolved in one location (Africa) and we haven't existed as a species for very long. D. Humans are not very genetically similar to one another.
Black-footed ferrets are an endangered weasel found in the Great Plains. If fire swept through the plains and only a few members of a population survive (lowering the gene pool) , what did they experience? a.Bottleneck Effect B.Founder Effect C.Mutation D.Natural Selection

What is Sympatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate them
Adaptive radiations can be a direct consequence of three of the following four factors. Select the factor that is NOT a direct consequence of adaptive radiation. Select one: a. Genetic drift b. Vacant ecological niches (niches are environment "space" where a particular organism has resources required to survive and reproduce) c. New evolutionary innovations d. Colonization of a new region that contains suitable habitat and few competitor species
Biologists sometimes say that “natural selection depends on the specific environment where a species lives.” What does this statement mean? A) A) If populations of a species are in different environments, traits that individuals need to meet their needs in each environment will appear. B) Traits can be helpful or harmful. If populations of a species are in different environments, some traits that are helpful in one environment might be harmful in another environment. C) Traits are always either helpful or harmful, and the environment of a population doesn’t matter. If populations of a species are in different environments, the same traits will always be helpful. D) Species were formed to perfectly match their environment. The traits of individuals in a species depend on the specific environment in which they were created.
What does the term evolution mean? A. The characteristics of species become more complex over time. B. The strongest individuals produce the most offspring. C. The characteristics of an individual change through the course of its life, in response to natural selection. D. The characteristics of populations change through time.
What is Macroevolution? A) The change of a population over several generations B) The history of a species from its origin C) The history of all populations and their descendants
