If two lava TIOws are separated bya short distance (say, less than a kilomeier), how could both lava flows come to be occupied by dark colored mice? (Select all correct answers) A. Dark mice could evolve on one lava flow, then migrate and colonize the other lava flow. B. Dark coloration could evolve independently on each lava flow. C. Genes for dark coloration could evolve on one lava flow, then move to the other lava flow through interbreeding of dark mice with light mice on the other lava flow. O D.A large population of dark mice could spontaneously be generated simultaneously on the dark lava flows.

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.
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.
Researchers have found fossils of Eocene horse species in Colorado. Deeper deposits contain smaller species, and more recent deposits contain larger species. How does this observation support the theory of evolution? A. It provides evidence that species change over time. B. It does not support the theory of evolution. C. It shows that all species are related to each other. D. It proves that environments have changed over time. E. It suggests that species are unchanging and of recent origin.

When dark-colored mice from two different populations living hundreds of miles apart were examined, the mice looked nearly identical. Their dark color was caused by two different genes. What does this tell you? (Note: More all correct answer) Group of answer choices A. Dark fur color evolved independently on each lava flow. B. there are at least two genes involved in creating dark-colored mouse fur. C. Dark-colored fur evolved only once in rock pocket mice. D. Under similar conditions, natural selection can favor similar adaptations. E. Different mutations in two different genes cannot generate the same phenotype.

EVOLUTION LINK Write short paragraphs explaining each of the following statements: (a) Natural selection chooses from among the individuals in a population those most suited to current environmental conditions. It does not guarantee survival under future conditions. (b) Individuals do not evolve, but populations do. (c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive. (d) At the molecular level, evolution can take place by the replacement of one nucleotide by another. (e) Evolution is said to have occurred within a population when measurable genetic changes are detected.
